Howto setup Folding@Home

[moz_21]

That P4 you have is a hot runner anyhow. Keep the fan clean and you'll be just fine. It should throttle or shut down if it ever gets waaayy to hot but that would probably only happen if the fan dies.

[jpkotta]

mahiyar, all of your questions are answered on our wiki: https://help.ubuntu.com/community/FoldingAtHome.

The HT question has it's own section. Yes, you can run two clients and get your CPU meter to 100%, but since you're already worried about thermal issues, it's probably not a good idea. There is a program that limits the CPU usage of a given program if you're still worried about temperature (link in the wiki).

Hello everyone,

Great info on setting up the folding client. However, i have 2 issues. I have a machine running windows vista and one running Kubuntu edgy behind an ipcop firewall. The first problem i'm having is that in Kubuntu, i've had the client running for about 2 days now and still no unitinfo.txt file. sudo updatedb and locate turn up nothing. I've verified the client is properly running with top and ksysguard. The other issue i'm having is that my windows machine is failing to send work units back, i get "could not connect work server (results)". I've port-forwarded port 8080, and made sure the windows firewall wasn't interfereing, but still get the same error. Any ideas anyone? I'd really like to donate!

Thanks in advance!

EDIT: I finally have a unitinfo.txt file, and i found that IE7 was the problem. I have no idea what took so long, but I'm happily crunching and hopefully sending units in now.

Excellent! I didn't waste my time reading the Debian docs (they were interesting anyway).

I've been running fah for a couple of months now, and it is working.

I'm not sure I have it configured correctly though for my AMD 64 X2 processor. When Fah is running, it never reaches more than 50% utilization, which is fine. However, my understanding is that it should scale down as more processor is needed. I never see fah go below 45% utilization, even when another process is dragging the system to its knees.

Is this normal behavior for fah? Its running with nice set at 19.

[jpkotta]

muguwmp67:

It sounds like you're only running one core. You may want to try the SMP client or if you used fah_install from the first post in this thread, then you should set it to run 2 clients. You want to run one UP client per processor, or one SMP client for all processors.

I have decided to build a machine as soon as Intel chips drop in price, which should be around April 22. Then I will be able to test my scripts with SMP clients and add an option for installing them. Right now, you can probably just change the name of the executable in install.sh. Has anyone tried this?

It is. You've set it up to use one core. Anything that isn't multi-threaded will show as 50% usage when it's going full bore. Since the majority of applications are still single-threaded you are able to run FAH at maximum usage on one core and just the OS and apps on the other.

That sounds exactly right. If you were running a single core (or if you run a multi-threaded application) it would scale back. FAH is very unobtrusive on every computer I've had it on. The big thing is ram. If you are running big-packets or the beta SMP client I recommend 1GB of ram (unless it's a dedicated folder; you can get away with half of that if you don't need to load a GUI).

I was thinking the same thing about the script but I don't have an x86-64 capable dually running Linux. If/when the 32bit linux SMP client comes out, I'll give it a try but until then I can't say I'm much help.

[muguwmp67]

Thanks for the explanation. I haven't noticed any performance problems while running fah, but was curious as to why it didn't look like it was giving away cycles to other apps. This also explains why the super_pi script comes up with roughly the same result whether fah is running or not.

[chewearn]

hi everyone
I started running F@H a few weeks ago; installed it using the fah_install script. Everything was running smoothly (after a few minor tweaks). Recently I started having problem uploading a couple of WUs, but found out it was server problem at Stanford side; so that should be resolved once the data server is fixed.

Anyway, on to the reason I am posting here. While investigating the problem above, I found out that I was running FAH502-Linux.exe. I recalled during the installation process this application was automatically downloaded by the fah_install script. However, I also noticed the latest version at F@H website is FAH504-Linux.exe.

Questions:
1. Is it ok to continue running version 502?
2. How do I go about updating to version 504?
3. If I update, will my existing completed WU be retained (or should I wait until successful upload before updating to version 504)?

Thanks for all help/feedback. :D

[ruudiculus]

Maybe the best thing you can do if you want to update is to copy the whole 5.02 folder and replace the 5.02 executable with a 5.04 executable. This way you can easily test if 5.04 continues working with your 5.02 WU's. If not (and your WU's are destroyed or something) )you still have the GOOD directory with a 5.02 executable and the original WU's. My quess is that 5.04 will continue working on the WU's fine, but this is a way to try.

Hey, thanks. Sound like a good workaround. I followed it, and it looks like the my finished WUs are still ok.

The only minor issue I noticed is that executable filename is coded inside the fah_install script, and i don't know enough about the script to be able to change it to "FAH504-Linux.exe". Instead I have renamed the filename "FAH504-Linux.exe" to "FAH502-Linux.exe".

[ruudiculus]

Haha, great workaround as well :D

If you want some sort of monitoring applet for your folding process, there's one on my website.

I recently have a conversation with you in the applet thread; reported a problem getting the applet added to the gnome panel. :D Haven't got around to investigation more about it. Instead, I have worked out another way to monitor using conky.

[l1oyd]

I think it should be set up but I don't think it is running

when I enter "start" in /opt/foldingathome/ I get error msg

start: missing job name
Try `start --help' for more information.


So how do I get a "job name"

Also I'm running the script from the wiki (https://wiki.ubuntu.com/FoldingAtHomeTeamUbuntu) after uninstalling the script in this thread

[Spartan.II.117]

i used the fah_install script and it worked great, then i had to re-install Ubuntu and so i used it again and copied my old directory but now it runs and works for a while i come back and it's no longer running. anyone else having similar issues?
P.S i'm running fiesty

[jpkotta]

I've had trouble in the past using restored backups. It's not guaranteed to work. The fact that it runs for a while suggests you did everything correctly, and the client is having trouble in spite of it.

[Spartan.II.117]

do you have any suggestions on how to fix it? uninstall/reinstall, remove work folder etc?

[jpkotta]

Maybe I'm forgetting something. Can you say whether or not this command returns anything?
grep foldingathome /etc/passwd
If it doesn't return anything, then it isn't installed completely, and you should keep your backup, uninstall, reinstall, then replace the installation with the backup (the installer does more than simply copy files).

[Spartan.II.117]

foldingathome:x:1001:1001::/opt/foldingathome:/bin/false

Like i said, it runs for awhile (15 min?) then quits. possibly when trying to write to the log.
(just realised that it's possibly related to a problem i've been having with gedit... investigating now... will post my findings within the half-Hr)

[Spartan.II.117]

well it's been nearly an HR and still nothing (it's still working) but it hasnt moved a percent yet, so i assume it's running properly.

[Spartan.II.117]

nope, it quit later, i ran it from the terminal today and it's gotten through about 6-7 percent, so once it finishes i'm going to un/re-install

[jpkotta]

I was thinking that maybe it didn't have the special f@h user created, but it does. Your plan is what I would do.

[Spartan.II.117]

yep, it finished so i re-installed and i caught it at the right time because the work server was down. so it now works fine!

Hi, Sorry if this is the worng place, I can't find an answer on the Forum.

How do I move a WU at 23% from one computer to another. An old P450 box is working on a big WU and and has crashed a few times. I want to put it on a faster cumputer so it will finish before the deadline.

I copied the Folding folder and all it sub folder to the faster box but it does not restart the old WU from the saved piont. It fails the run any WUs. With new FAH504 download and install it retrieves a new WU.

I must be missing a setting in the -config after changing computers.

I a new to Ubuntu and Folding@Home.

Thanks

Is the slow computer a Windows machine? You need to jump through some hoops to move from Windows to Linux. Look at the Sneakernetting link on the F@H wiki page (see my sig). That will tell you 90% of what you need to do to move WUs from Windows to Linux (the other 10% is installing Wine).

Anything you set with -config is stored in client.cfg, so all settings should be copied.

[pjc330]

Both the old and new computers are setup with Ubuntu 7.04.

I looked again at the Sneaker netting page. I think I did what the page said about moving WUs between computers with the same OS. I know nothing about a Ubuntu Registry (or if it has one). Do I need to copy some thing else to the new computer to get it to recognize the old WU? I did move the entire FOLDING directory/folder to the new computer.

I want to move the old WU to a different computer and continue folding that WU on the new computer that is network and internet connected.

I just can’t get the faster computer to work the old computers WU. It is folding a different WU as we speak without any problems.

The old computers WU is: p4308_dpdp-ii I think it’s a Beta WU, that may have something to do with the problem.

I will keep trying.

Thanks

[jpkotta]

There is no Ubuntu registry (thank goodness). You would have used the Wine registry if the slow computer was running Windows.

All I can say is that F@H was not designed to move WUs around, so there is probably some hidden undocumented thing that is causing the move to fail. Maybe check out the semi-official F@H forums http://forum.folding-community.org/. I have moved WUs between Windows and Linux, but it was not easy, and the computers I was using were very similar hardware-wise.

Ugh. You probably got this from the forum thread. I hate the fact that only one person can edit a post. Wikis are better for this kind of thing. I'll talk to an admin about removing the old version of the script.

I installed Folding@Home earlier today and have some questions:

-If I close the terminal window, does that close f@h, or will f@h run in the background? Is there a specific command for exiting f@h? (I shut my computer down at night, and I don't want to screw up f@h by exiting the program incorrectly)

-If closing the terminal window does close f@h, is there anyway to prevent this? (should I run f@h in the background? As you can probably guess, I'm a linux newbie.) I'd rather not have to keep a terminal window minimized all the time.

-Why doesn't my username show up on the stat list on the website? (I can't check now because their server is down, but earlier it wasn't listed.) Is it because I haven't finished folding my first protein yet?

-I'd like to join Team Ubuntu. I do this by going into config and setting my team to 45104, right? Can I do this while F@H is already running?

Thanks.

that depends on what command you use to start the fah client...

-If closing the terminal window does close f@h, is there anyway to prevent this? (should I run f@h in the background? As you can probably guess, I'm a linux newbie.) I'd rather not have to keep a terminal window minimized all the time.

if you add ' &' to the start command, that will put it in the background, and you can safely close the terminal. if you want to later kill the process, just find it in the process list (in system monitor), and kill it.

-Why doesn't my username show up on the stat list on the website? (I can't check now because their server is down, but earlier it wasn't listed.) Is it because I haven't finished folding my first protein yet?

yes, your username won't show up until you submit your first completed work unit (and there will be some delay after that, since that list isn't updated real time.


-I'd like to join Team Ubuntu. I do this by going into config and setting my team to 45104, right? Can I do this while F@H is already running?

Thanks.

you have to restart the fah client in order for the changes to take effect.

i think that takes care of all your questions. ;)

[GreenGirl]

Thanks. One more question: when I close the program, it saves the progress it's made so far, right? I'm not going to lose the data because it didn't finish folding the protein?

[nanotube]

Thanks. One more question: when I close the program, it saves the progress it's made so far, right? I'm not going to lose the data because it didn't finish folding the protein?

yes, it saves progress periodically, and fairly frequently. so you won't lose anything to speak of. :)

[GreenGirl]

I tried running it in the background, closing the terminal window, opening a new terminal window and typing "ps", but the only processes listed were bash and ps. So I tried running it regularly, opening a new window (while it was running in the other window) and typing "ps", and it still wasn't listed.:confused: Any idea what I'm doing wrong?

[freebeer]

try:


ps -e


The -e parameter tell ps to show every process. Without it, you only see processes related to your logged-in account. (Folding runs as a root process, I believe.)

[glotz]

Depends how you installed it. I used the script provided with sudo and then it's running on it's on 'foldingathome' account.

[GreenGirl]

ok, it shows up if I use ps -e, but if I close the terminal window it disappears from ps -e, even though I was running it as ./FAH504-Linux.exe&

[Swab]

ok, it shows up if I use ps -e, but if I close the terminal window it disappears from ps -e, even though I was running it as ./FAH504-Linux.exe&

Closing the terminal will stop the process. The wiki has an script to setup FAH as a service which resolves this issue.

[GreenGirl]

ok, thanks. :)

[GreenGirl]

I installed finstall and rebooted my computer. It looks like fah now starts automatically. :) ps -e is saying:

5286 ? 00:00:00 FaH
5301 ? 00:00:00 FaH
5303 ? 00:00:05 FAH504-Linux.ex
5304 ? 00:00:05 FAH504-Linux.ex

Is FaH supposed to have 4 processes?

Only problems I'm having is that qd (which was supposed to install with finstall) doesn't seem to exist, and fpd is saying I'm Anonymous and Team[0], even though I entered my username and the ubuntu team number when I configured FaH.

[jpkotta]

For the curious, you must do more than background a process to detach it from a terminal.
(exec some_command) &
The '()' forks the shell into a new one (one that isn't attached to the terminal), and "exec" replaces the new shell process with the some_command process, which a) means you don't have an extra shell running, and b) starts a bit faster. I have in my ~/.bashrc a "daemon" function that will do this.
# super stealth background launch
# disconnects from launching shell, keeps running until killed
function daemon
{
(exec "$@" >&/dev/null &)
}
daemon some_command

Now, back on topic, F@H has several processes. The FahCore_....exe processes are threads (I think) of the core, which is actually doing the work. There is also the client, which starts and stops cores and uploads results, etc. But it looks like you (GreenGirl) have two clients running, which may or may not be OK, depending on what finstall does. If you have 2 CPUs and you are not running the SMP client, you'll want one client (plus its associated cores) for each CPU.

[GreenGirl]

Ugh, I'm sorry I'm being such a pain about this but does anyone know how to uninstall finstall? I want to be able to see my progress (fpd isn't working now for some reason) and now that I know how to get it running in the background without a terminal window (thanks, jpkotta) I think it would probably be better to just manually run it in the background and move it to the foreground whenever I want to see the progress, rather than have finstall handle everything.

There is a text file you can check for progress... unitinfo.txt if I recall correctly. Sorry I'm not folding at the moment!

Yes it is, I wondered the very same thing and found the answer at folding@home forums.

[SuperAndy]

After following the howto here (https://help.ubuntu.com/community/FoldingAtHome), specifically this bit:

"For me this was all I needed as it automatically created the init scripts I needed to start after reboot. However the init scripts don't seem to work for everyone, so if you need to do it manually:

1.

Make a file called foldingathome in the /etc/init.d directory:

gksudo gedit /etc/init.d/foldingathome

2.

Paste this in:

#!/bin/sh
# /etc/init.d/foldingathome for Ubuntu
# Start the F@H service.

pushd /home/YOUR_USERNAME_HERE/foldingathome/
su YOUR_USERNAME_HERE -c "screen -d -m ./folding start"
popd

3.

Save and exit
4.

Make a symlink into the /etc/rc2.d directory:

sudo ln -s /etc/init.d/foldingathome /etc/rc2.d/S99fah

Now, when i start, the booting freezes about 4/5th of the way through.

If i stick it in recovery mode, i get to the andy@andy_desktop promt, and then it freezes, and i get a:

SOFT LOCKUP DETECTED ON CPU#0!

The exclamation mark really takes the ****... I am pretty sure it was that init.d stuff. I have tried deleting the /etc/init.d/foldingathome entry, but it makes no difference (i am using a livecd to get in there to edit the stuff).

Anyone got any ideas over this?

[jpkotta]

If you deleted the f@h stuff, it shouldn't affect the system at all. It sounds like a hardware problem. I couldn't tell you much more than that. Maybe try a different kernel?

[SuperAndy]

i have tried the two kernels i have in grub. the thing is, its the only thing i changed to my system, nothing else. there's nothing it could be. i will have another bash though...

[sad_iq]

Ok...here goes...the first time I read this howto...installed it...works great(the install part)...but when I try to run it it prints this: sudo /etc/init.d/foldingathome start

Yes. Yes they should. I've emailed the admins twice. I've tried to contact the original poster. This is why forums suck for information that has any sort of permanence. Wikis are much better for documentation. I must say that the script got much more exposure in the forums, but the howto really should have been something more like "Here's a link to the wiki page, where the real howto is. Post your problems here.". Anyway, if the admins ever get back to me, I'll redo it properly.

[otchster]

I need to know a few things....


First off, I have this set up on an old PC running Ubuntu.. I have it set up with no monitor, so I have tap in remotely.. I have installed and successfully can run F@H...

My question is.. If puTTY (the program I use to connect to the machine) looses its connection, will F@H still run???

Could I actually close puTTy after I starte F@H, that way I don't always have to have a connection terminal running on my other computer ??

If I do get disconnected, will F@H save its current progress for the next time, or does it start over???


Thanks all :-)

Thanks all :-)

about your first question: easiest thing is to try it and see. connect, start fah, disconnect, connect again, then see if cpu is still being eaten by the fah process or not. :)

if the fah process is killed by disconnect, you could try starting the process with & at the end, which would put the process in the background... but i'm not sure if that will keep it alive.

a surefire way is to use a neat little program called "screen", which lets you run a bunch of virtual "terminals" in your shell session, and which you can connect and disconnect from between logins, so that should let you run fah even when you're not connected.

you could also run fah at boottime in an init script, which would leave it running without you having to do anything at all. :)

as to progress saving- fah periodically writes its progress to disk, so you don't lose all your work if something crashes. so no worries there.

[jpkotta]

My question is.. If puTTY (the program I use to connect to the machine) looses its connection, will F@H still run???


If you start it correctly, yes. Use one of the scripts from the wiki (fah_install or finstall); they are written for this purpose. If you are curious, read this post: http://ubuntuforums.org/showpost.php?p=2985303&postcount=295.

screen is good too, but in this case I'd say use the scripts because they will also start it at boot time, which is almost certainly what you want.


If I do get disconnected, will F@H save its current progress for the next time, or does it start over???

It saves every 15 min by default. You can set this during the initial config or by running it with the -config (or -configonly) option.

[legatek]

I would like to report a bug with the latest version of the install script on the Wiki page.

I have been happily folding on my home computer (Edgy) for a couple of days so I decided to also load F@H on my work computer (Feisty). Currently there are two scripts on the Wiki page, one dated 20061219 and the other still in beta dated 20070702. I downloaded and installed the beta script to install F@H. Since I connect through a proxy at work I had to download the client manually and move it into /opt/foldingathome/config. The problem is the beta script will not recognize if a client exists at this location unless it installs the client there itself. The client version doesn't matter, nor does it matter if the client has user or root permissions. It is not recognized. However, the earlier script works fine, so now I have two computers contributing to Team Ubuntu world domination.

In case it matters, I should mention that I first had to create the foldingathome and config directories manually, since the install script didn't do it before trying (unsuccessfully) to connect to the Stanford site.

[jpkotta]

Thanks for the report. Can you download the client by hand and put it in the same directory as the install script? That was the intention for manual downloads. I will update the docs to reflect this when I get a chance.

[legatek]

OK, that works fine. The problem was that the install script directed me to save the client to /opt/foldingathome/config myself. Thanks.

[freebeer]

I used the script from the wiki to set it up on my dual Core machine. The install seems to have gone well, except that the script didn't correctly identify that I have two CPUs. So, as directed, I told the script that I had two. It dutifully installed the two setups, but the second one failed to launch (so I'm only running one instance right now). I manually edited the .cfg file in /opt/foldingathome/2 to change the machineid to 2 thinking that might help (it was set as "1" like the one that's working) but that didn't seem to have the desired effect. Where'd I mess up?

I'm new to the dual-core thing and I thought it was interesting to note how the one instance would flip between cores in htop. One cpu would be reporting 100% usage for a bit, then the second cpu would be at 100% while the other one dropped to near zero. Is this normal "load balancing" that I'm seeing? Just curious.

[Spartan.II.117]

yes, it's load balancing, when you have two cores running F@H it wont happen anymore. as for the install, i had a similar issue when i installed it on a dual processor server i had to run etc/init.d/foldingathome start each time i started the computer.

[freebeer]

Thanks for the confirmation on the load balancing.

Had to start it manually, eh? Bummer. I don't do much in the way of rebooting... I just let 'em run. I guess I'll have to play around a bit more to see how to get that second one configured and running. I like the idea of it just running at start-up (otherwise I'll forget to restart them, or won't be here post-power interuption to get them going again).

[Spartan.II.117]

i never did any research into it myself, it was a server and it ran 24/7, so it was not a big deal/

[brandonlw]

Hey folks, I am new to the whole Ubuntu/Linux world. My brother wants me to learn more about it so I threw it on a spare machine here at work. I wanted to get into the FAH stuff because I have extra machines sitting around, so I figured why not. Sure I could go the easy route and leave Windows on them but I hate not being able to figure something out.

Followed the posted instructions and was simple enough until I got the LOG at the bottom. (NOTE ... I originally joined the Ubuntu team but after trying it 10 different times I stopped entering it in :) )

We are behind a firewall here at work but I know that isnt the problem because we have Windows machines running FAH, unless I am just blind to something obvious. So .. where should I start troubleshooting? I found one related topic on google but it did not help me at all

Have you re-tried recently? Sometimes their servers are down for maintenance. (The 403 error indicates another issue from what I've read about it, but I'm guessing it's just a maintenance thingy.)

[glotz]

In about one month time (http://folding.extremeoverclocking.com/team_overtake.php?s=&t=45104)(?) we will enter top 100 folding@home teams. I want that on ubuntuforums.org frontpage when it happens. It would also be nice on ubuntu.com.

I'm no people person and I cannot make it happen however. Are you and can you? That's the challenge and your time frame is approx. 1 month.

Make it happen!

[brandonlw]

Yep ... at least 4 or 5 times a day. And it retries 11 times on its own with a minute or so intervals. I have 2 other computers and my laptop (2 XP and 1 98 ) all on the same switch running FAH just fine. So I'm trying to figure out if there is some setting in Ubuntu that would need to be changed (Which wouldn't make sense).

[Spartan.II.117]

brandon, how did you install f@h? if you did'nt already, i would recommend FAH_install from the wiki

[Phalse]

I just noticed that there is a version 6 of the SMP-x64 client. I am having a problem getting this to run. I have tried following the wiki but I still can't get it to go. Could this be because I'm trying to run this from the live CD?

I'm trying to learn how to work with Ubuntu while doing this so this is the first time that I'm jumping into Linux. I figured Ubuntu would be a great start :)

[OfficeLinebacker]

I think you have to pass a new switch to the client, -smp. So for example if the CLIENT OPTS used to be '-forceasm -verbosity 9' they would become '-foceasm -verbosity 9 -smp'

Seemed to work for me after a few go rounds.

I think you have to finnish one unit for the file to appear. Here's how to setup any windoze box http://folding.stanford.edu/So, how do i verify that it is running at all?

[glotz]

:) Thats a good question! Just wait a few days and the file should be there. Maybe someone else knows better.

[chewearn]

Actually, I don't think that is correct. unitinfo.txt should appear as soon as your unit is downloaded and started folding.

For example, here is the unitinfo.txt currently on my system:
Current Work Unit
-----------------
Name: p2566_BBA5_ext
Download time: October 6 15:19:46
Due time: December 27 15:19:46
Progress: 3% [__________]
To check if it is running, look also for the file FAHlog.txt (in the same directory), which is a log of the folding progress and various messages. Also, check your CPU usage; you should have process FahCore_xx.exe (xx depends on the unit being worked on; e.g. FahCore_79.exe) taking up almost 100% CPU.

[glotz]

AstalaVista is that your first unit ever? That's what I meant.

[chewearn]

Alright, that's not my first unit.
But I have set-up F@H in a couple of machines, and unitinfo.txt always appeared as soon as folding started.

[chewearn]

Crap it isn't running then. I wonder what I'm doing (did) wrong!

You didn't say how you set-up your F@H. If you give more info, maybe we can help.

Actually, I now prefer the simplest method; simply put the FAH504-Linux.exe into a subdirectory of home; e.g. ~/FAH/
Then run FAH504-Linux.exe from terminal.

On one machine, I have a dual core; then I simply have two subdirectories, FAH1 and FAH2; and again, run FAH504-Linux.exe directly in each subdirectories.

This method can also be applied to running F@H in Windows. The only downside, you cannot close the terminal window.

[jpkotta]

You do not need to keep the term open!

I'm adding this to the wiki.

[jpkotta]

I've updated my fah_install script. Get it in the wiki (https://help.ubuntu.com/community/FoldingAtHome). It adds the 6.00(beta1) client. You should be able to update everything by running the following commands:

sudo /etc/init.d/foldingathome stop
sudo tar zcvf fahbck.tar.gz /opt/foldingathome
sudo ./install.sh install
sudo /etc/init.d/foldingathome start

You will want to make sure you allow the installer to update the /etc/default/foldingathome file, since the 6.00(beta1) client needs an extra option for SMP work units.

[ant2ne]

You didn't say how you set-up your F@H. If you give more info, maybe we can help.I used the install script mentioned on the first page of this thread. sudo ./folding_install.sh install

[Spartan.II.117]

you might want to try the script that jpcotta was talking about , it's very good. (ps thanks for updating it, my install quit about a week ago and i couldn't figure out why for awhile.)

[evets]

I've been folding for 2 years, come next month. I fold on 3 different teams.

So, first of all, thank you for your contributions, and this neato tut on setting up FAH on Ubuntu!

Secondly, I was hoping there would be a team Ubuntu, and now that I know there is, I'll be folding for "Humanity" pretty soon, as well. I am just waiting on some parts to finish rebuilding my wife's winbox, then I can take my old Dapper box back, and load up FAH using your tut.

Thanks again!

[Swmmrman]

Been having a frustrating issue. After a computer crash(Very literal variety), I had to reinstall ubuntu. then i tried to reinstall my folding at home. However, It seems to install just fine. But it never creates the FAHlog.txt file. And never seems to run. when i run and sudo /etc/init.d/foldingathome status. Says the client is running And the FAHlog.txt isnt there. However, upon checks(After reading this entire post) The processes are not running. And it can easily uninstalled as if its not running. I get no increase in processor usage. Issuing the start command results in it saying the client started. But nothing changes.

I have noticed during install it claims the foldingathome group and user were created. However after several checks threw groups and users. No such group exists. When uninstalling it says it cant delete the user/group cause it doesnt exists. I have even gone to the lenghts of created the user and grp prior to install and no go.

Im running Ubuntu 7.10 Gutsy. Trying to install the SMP client. Have got the libs needed. Installed Via Wiki instructions. Using sudo. Not sure if any of this will affect anything. I have webmin installed. And also have installed a postfix server as well as a webserver.(and many other things Wow rocks on ubuntu) I keep the firewall set to allow all.

Sorry for the long post. Just wanted to get all the information I have at once. Any help would be appreciated.

On my last install attempt i checked the logs. It did infact successfully create and delete the user/group foldingathome. I also confirmed via webmin that while it was installed, The group was there and so was the user. However same fail message. An interesting note. on another computer with a fresh install of ubuntu(I borked it). It is doing the exact same thing.

On a bright note. It is installing and runing under wine.. Albeit slowly.(2 frames per min vrs 30 sec) At least i can still fold.

Btw have any of you had experince with fully setup compiz(The settings manager installed and cube going) And multi monitors(Somehow my settings borked it other computer badly)
When i got the second monitor connected. It locked and killed tfter reboot i could log in however i could not get ful xserver. All i had was a tan background(no background set) even under other sesions.

All of your files look OK; it looks like the client hasn't been run except for the configuration mode, but we knew that. Try running the client manually, and post the output:

sudo su --shell /bin/sh --command "cd /opt/foldingathome/1/ ; ./fah6 -smp" -- foldingathome

This is off topic here. If you want to discuss further, you should make a new thread.

I will say that I got it working on dual monitors in Xfce. I got the dual screen set up through nvidia-settings (twinview). Then I got compiz working, and I don't remember anything special I had to do to make it work with 2 screens. Followed this guide: http://ubuntuforums.org/showthread.php?t=623752.

ok intersting thing, Says the cleint only supports 64bit systems.... I know for a fact that this is 64 bit...
Note: Please read the license agreement (fah6 -license). Further
use of this software requires that you have read and accepted this agreement.

This client only supports 64-bit linux machines. Your machine was detected as ''.

My good man i must thank you for helping me find my error. I had grabed my 32 bit ubuntu CD instead of the 64 bit. I will label them to prevent further issues.(Though i will still try to find interesting ones)

I installed F@H using the installation script folding.sh as directed on this howto (https://help.ubuntu.com/community/FoldingAtHome/Install).

However after I try to add my own user name and team name the MyFolding.html still shows Anonymous and None? I tried to change to my name/team using this...
sudo ./folding.sh --rename

The client.cfg file DOES show my new user name and team, but it doesn't seem to be taking. I have this running fine on 3 other machines.

By they way, how can we contact Christer Edwards? It looks like the wiki I listed above needs updating... It doesn't have the folding.sh script. Or am I doing it wrong.

Thanks.

[glotz]

The point of wikies is anybody can edit them. Feel free to.

I used the link in my signature to install F@H. Maybe give it a try.

[kpictjl]

After looking a little closer.

In this folder.../var/lib/folding/foldingathome/CPU1.
FAHlog.txt says F@H recognizes my User Name and Team number.
[04:01:44] - User name: kpictjl1 (Team 68208)
client.cfg has my User Name and Team Number.
[settings]
username=kpictjl1
team=68208

however, MyFolding.html, still shows Anonymous.
Your information
User name: Anonymous
Team number: 0

mmm...so why doesn't MyFolding.html get updated? Mostly I'm not confident that this machines "work" will be reported correctly.

[kpictjl]

I filed my above issue as a bug here (https://bugs.launchpad.net/folding/+bug/175460).

Christer will fix it in the next release, but my workaround is to delete Myfolding.htlm and then restart the service.

[Swmmrman]

Where can i find the protien think gui? I thiought i found it in this thread, But have had no luck locating it
Edit: NVM found it

[Swmmrman]

Ok found and installed protien think. However.. All info is blank. I know for a fact. that i have a unitinfo .txt anyone know why it would be blank.

[jpkotta]

The wiki pages were getting really cluttered with all the different install methods, so I made dedicate pages for each method and just links in the main page.

i dont know what methods it uses to extract the core, but that seems to be the problem as far as i can tell. did this just start(after having used F@H for awhile)? if not (new user/install), try re-installing

[war59312]

OK deleted the .exe files and killed the process using system monitor and then started back up via sudo /etc/init.d/foldingathome start and what do you know, now its working fine. Really strange.

Yeah was a new install, newbie here... thanks anyhow... learning quick hehe...

[Swmmrman]

I had one of mine start doing that after fetching completing a unit. Did that about 10 times. (Same core name too) Then deleted the core and moved on by itself. My guess was it was a server with a bad work packet.

Got it working on my laptop, now here a odd request, but is there a way to put in a script that stop it when the laptop is running on batteries?

Not odd at all. See the second bullet of the first post of this thread. It will tell you to go here: https://help.ubuntu.com/community/FoldingAtHome#head-353ddb49ec5a97223b3e0f1be7d8a7acfab7f59e

Is there a way to run protein_think aside from putting "python fahmain.py" in the terminal?

It's my 1st time running Linux, but I've been folding for almost a year. I just switched my 2 PS3s running 24/7 to Team Ubuntu:) They cut through WUs like a hot knife through butter

Thanks in advance

[Spartan.II.117]

jpcotta:
could FAH install be updated for 6.00 beta 2?
also i believe you could create a deb if you could configure your script into a makefile. these would be awesome.

Spartan

[jpkotta]

I updated it a couple of days after the previous beta expired.

I didn't want to use a Makefile, because then people would need to install make, which AFAIK is not installed by default. I believe you only need a tarball and a few scripts for a deb, but I've never gone into the details. In any event, I like Christer Edwards's script, which just uses finstall. It just doesn't do the SMPs right yet. As soon as it does (and I haven't tried since the beta expired), I'll probably just use that.

[Spartan.II.117]

it isn't working properly for me, i had to get the new beta off the site and run it manually. also the make script was for creating a .deb, i should have specified, but a channel from stanford with auto-updatable .debs would have been awesome.

I just retested it and it works for me. What exactly goes wrong? BTW, you need to uninstall and reinstall, I don't think update will do it for you. Perhaps "update" is poorly named; it doesn't update everything, it only updates the scripts that I wrote. This is because if you update the client, I just assumed that the WUs would not be compatible, and you'd have to start over anyway.

[Spartan.II.117]

i figured it out: the scripts did update, and i got the client from stanford but forgot to change the user on it. everything works now.i just wish i could get all the SPARC's around campus working on it.

[jpkotta]

A new beta client is out, which means the old one is expiring soon.

https://help.ubuntu.com/community/FoldingAtHome

[Spartan.II.117]

I tried installing with the new script, but when i go to start it it shows failed and my processor usage does nothing.

[jpkotta]

You mean that the installation appeared to be successful, but when you run sudo /etc/init.d/foldingathome start it fails?

Try replacing /etc/init.d/foldingathome with the attached script. It should print out some error messages.

[Spartan.II.117]

well, the new script starts it fine. and based on the noise of my computer last night, i think it was succeeding but reporting failure.

[jpkotta]

Good. All that's different is that I removed the --quiet option from start-stop-daemon. The client always takes a few seconds to actually get up and running, up to several minutes if it has to up/download work units.

[jpkotta]

I just updated to Hardy on some of my machines. It seems like the Linux process scheduler is really weird. F@H is niced to 19, yet it seems like the scheduler is giving it more time than other processes. This, in turn, screws up frequency scaling. I'm still looking into this problem; I haven't seen any good workarounds.

[Spartan.II.117]

is this 64bit or 32 bit or both? i have noticed no such issues on my 64bit system.

[jpkotta]

It's both, but was more noticable on my 32-bit machine because it's a laptop (cpufreq scaling) and it is a single core. Anyway, I found the problem: the new CFS process scheduler in the kernel. The scheduler tries to give groups of processes their "fair share" of cpu time. Apparently, the way of grouping processes is by UID. Since I run F@H as it's own user (I really think this is the correct thing to do), it was basically getting half the CPU time, and my processes were getting the other half. There is a mechanism for tuning the share of CPU time each UID gets, in /sys/kernel/uids/$UID/cpu_share. Apparently the default is for everyone to get 1024 "units", I set foldingathome to get 16 and it works much better.

<rant>
I'm questioning the wisdom of adding the CFS to a desktop distribution, or at least this particular policy. When I'm on a desktop computer, I'm the one who's running programs; background jobs should have a low priority. CFS is probably great for servers, but I'm not convinced of its utility for desktops.
</rant>

Edit: Apparently, this is already getting fixed: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/188226

The fix is to add
deb http://mirror.cs.umn.edu/ubuntu/ hardy-proposed main restricted

(use your favorite mirror or us.archive.ubuntu.com instead of umn) and install the correctly configured kernel with sudo aptitude update && sudo aptitude upgrade && sudo aptitude install linux-generic

[KAdams4458]

Well, I'm a little baffled. I've been tinkering with getting the client installed and running through out the day, and I'm hitting a wall. Maybe one of you could point me in the right direction, because I'm stumped.

My system is single-core 64-bit. I can successfully install everything, apparently, but nothing ever shows up in the system monitor. Hmmm. Look at this:

To start folding right now, run `sudo /etc/init.d/foldingathome start`.


user@Vera:~/fah_install$ sudo /etc/init.d/foldingathome start
* Starting Folding@Home client 1 [ OK ]

Looks normal, right? After seeing nothing happening, I decide to try this:

user@Vera:~/fah_install$ sudo /etc/init.d/foldingathome stop
[sudo] password for user:
* Stopping Folding@Home client 1 [fail]
user@Vera:~/fah_install$


Okay, so now I'm confused. It says it starts, but never really does, since it never appears in the system moniotor, and stopping it fails. For that matter, everything fails except the start command. After dinking around with this and getting no where for the better part of a day, I decided I better ask around, since someone else may all ready know exactly what to do. I've lost enough hair today, and I'd rather keep the rest of it for as long as I can. :)

[freebeer]

I don't really know... I'm not familiar with system monitor. I wonder if it only monitors non-root processes? *shrug*

It looks to me that it's running. Have a look at your unitinfo.txt file... you said you let it run for a while? If it's running for a while, you should see some progress. Also, after you run the start command, can you check the processes with top or htop? You should see it there.

It doesn't show up in top, either. I just checked the unitinfo.txt, and after supposedly running for over 24 hours, it still has not been created. Something is definitely not right, and I can't seem to figure out what that something could be.

[freebeer]

hmm... I'm not sure. With top and no progress on unitinfo.txt, I'd have to conclude that it's definitely not running.

Have a look at your FAHlog.txt file. Maybe there's a clue as to what the problem might be.

[frbe0101]

I been able to make turn on and turn off buttons for folding@home, how do I tell it (in terminal) to run on just one core instead of two cores?

[jpkotta]

How did you install it? Do you want to make this configurable or just permanently disable one of the cores?

If you're using the SMP client (64-bit) you can't make it use only 1 core.

[DeaconBlues]

Is there a way to get Folding@Home using your GPU instead of CPU?

It says in the following link that only Windows is supported at the moment:

http://folding.stanford.edu/English/FAQ-NVIDIA#ntoc8

I read somewhere you get much faster calculations using the GPU.

http://folding.stanford.edu/English/FAQ-NVIDIA#ntoc8

I read somewhere you get much faster calculations using the GPU.

That's the official FAQ, and if it says Windows only, then you need Windows. I doubt any virtualization solution will work either, since that would still use the Linux driver. It sucks because GPUs do indeed calculate faster (there is a trade off: the things they can calculate are limited), and it appears that the effort to make a Linux version isn't worth it to F@H.

[mptpro]

Anyone think they'll release a simple installer (I do miss that days of Windows .exe).

Or least put it in the repositories (or the add/remove), and have it show up inthe "Applications" menu, AND have a grpahical client.

I installed F@H on two ubunut boxes and four winxp machines. The first time I did it with ubunut took me over and over, the second machine took about 10 minutes.

Windows took about 3 minutes.

And the windows has a graphical interface so I can see that it is working.

I know I can do all these things with command line, but to firgure it out the first time is a pain.

sorry for the rant.

[glotz]

It's a good rant but on wrong forum.

[jpkotta]

Christer Edwards is working on a .deb and getting it in the repos. https://help.ubuntu.com/community/FoldingAtHome/origami

As far as graphical client goes, try the Windows one in wine maybe? The console one is better anyway, because it runs all the time, even when no one is logged in (in both Windows and Linux).

I'm still new to ubuntu and still trying to get a the flow of things,
but I'm not giving up on it. It's on my main rig and I can get

But I haven't been able to get F@H on my main rig.
I keep messing up some where, So is there a place I can like
get spoon fed on how to do it.
A friend told me to get "Beginning Ubuntu Linux- From Novice

Which I did, just got it. But I like to fold while I'm reading
it.

So I've managed to to folding install... I have and Instal Core2 Duo, but it only detected one core. I'm looking for a way to install another single core client beside the one I already have, but with a differnet machine number (so it uses a differnet core). I tried running the install.sh, but it says a client is already installed and will only accept 'reinstall' and 'uninstall'.

So how do you pull off running two single core clients at the same time?

Thanks,

Josh

[jpkotta]

I assume you're using the script from https://help.ubuntu.com/community/FoldingAtHome/fah_install. In that case, it tells you how many cores it detected, but in case it's wrong, you can specify the actual number. You must uninstall and then install. "update" is not what you're looking for (see the wiki page above). Also, if you are running a 64-bit OS, you should only run one client.

[spudgunner]

Therein lies my problem... it never gave me an option as to how many cores I have, and I installed the 32-bit client, so it should have. I have no idea what to do.

[jpkotta]

spudgunner, try the new script in the wiki.

For anyone running Protein Think.
I just finished a new release of Protein Think (0.0.5-a) that addresses the couple of problems people were encountering. My ability to test the application is limited, however, so if you run into any problems with it, please let me know.

Get it here (http://sourceforge.net/project/showfiles.php?group_id=164311).

This release fixes:

- Difficulty reading new unitinfo.txt files
- Difficulty in which program would fail if certain data was not available. Now it will continue running, even without this non-critical data

Enjoy!

PS - If anyone happens to be folding on a multicore machine, you could help me by copying folders 1 and 2 and sending them to me. I want to upgrade PT to handle multiple cores, but don't have access to one. Thanks.

I'm trying to install F@H on 8.04 server and when I try to start fah, it says: "No such file or directory."

I'm currently using (or trying to use) the F@H Linux SMP 6.23 beta R1 client.

# ls
fah6 mpiexec
# ./fah6
bash: ./fah6: No such file or directory
#

Help? Please?

*edit*
n/m. Got it.

For Ubuntu 8.04 Server AMD64, you need to run


$ sudo apt-get install ia32-libs


in order for it to run properly.

[bbarcelo]

I have had F@H installed for the last several weeks or so and installed it using the finstall method listed in the Ubuntu wiki documentation. However, I found that even after several weeks, so statistics were being sent to the F@H site. This caused me to question whether any data was being sent. I decided to remove F@H and try re-installing using a different method.

I downloaded origami through aptitude and looked up the proper command to install it (sudo origami install etc..) but I receive the following error:

###############################################
# the root user shell must be /bin/bash #
###############################################

However, I'm 99% sure my shell is bash but to check I performed the following:
$sudo -i
#ps -p $$
which yields:
PID TTY TIME CMD
2129 pts/0 00:00:00 bash

I've tried everything I can find via Google and searching the Ubuntu forums for related issues didn't help much. I hope someone in this thread can help out. Thank you.

Heavy-handed is oft a word accompanied by trouble down the line. What makes this approach unfavorable? Is there any other approach that might solve the problem with a bit more.. finesse?

[jpkotta]

It really shouldn't cause any problems. Bash syntax is supposed to be a superset of Bourne shell syntax. A few releases ago, Ubuntu made Dash the default /bin/sh, which broke a lot of things that assumed that /bin/sh was actually Bash. The converse or this is false - anything that works for Dash should work for Bash.

The proper fix would be to either make root's shell bash (which it appears to be already), or to fix whatever is spitting out the warning.

To be sure that bash is actually root's shell, check
cat /etc/passwd | grep root

It should look something like this:
root:x:0:0:root:/root:/bin/bash

I would ask origami's author about it: https://bugs.launchpad.net/origami

I will ask the author as well, but could it be that if I change the line above the look like this:

..that I won't break anything and perhaps satisfy the origami installer?

edit #1:
I decided to go and test my theory and sudo -i works without any warning, so bash is being called correctly I assume (unless a system restart is required to institute the changes I made in /etc/passwd). Origami's installer finished but the startup script failed to start. This is an problem related to my processor though so I'll work on sorting that out next.

Yes. It should always be an absolute path anyway, for security reasons. I believe the proper way to do it is with
sudo usermod --shell /bin/bash root

Well, origami has apparently installed successfully but when I run sudo origami start, the following happens:

Starting up FAH client(s) on 1 processor(s):
Starting FAH client at CPU1...
FAH client #1 startup: OK


Starting of FAH client(s): FAILURE

I'd love to read the log file or something on this but I haven't found it ... yet. I'm starting to think maybe origami is more trouble than its worth and to just download the client off their site.

[paintandswim09]

(Sorry for the thread jack, I couldn't find a better place for this, and I didn't think it was worth its own thread)

I'm running F@H on a dual-core laptop that gets used by the whole family, and we typically log out when we're done, so there's a fair amount of time that the laptop spends sitting around, with only the screen turned off, with nobody logged in. Since F@H technically runs as a process of its own user (that _is_ right, correct?) is it still running when no humans are logged in?

BTW ranked #472 on TeamUbuntu, top 15% F@H wide

[jpkotta]

paintandswim09:

This is more or less the official F@H help thread for Ubuntu. You're not off topic.

It depends on how you installed it. If you used one of the scripts from the wiki, then it should be running when no one is logged in. You can check by running top or another process monitor and seeing how long the F@H processes have been running when you first log in.

Assuming the init script is called "foldingathome",
sudo update-rc.d -f foldingathome remove
You could also use something like sysvconfig.

Why all my FAHCORE_A2.exe processes are using least than 10% of CPU each one?

I am using the 6.24 SMP client in a Q6600 with 4gb of RAM and Jaunty 9.04.

Not really. Nothing looks weird in your logs. Although I don't think you need the -local option on Unix, and I'm not sure if -smp takes an arguement.

You could try the official forum http://foldingforum.org/. You could also try purging F@H from your system and reinstalling.

[swoody]

Hello everybody! I just wanted to throw out a reminder to everyone here, as well as anyone who may stumble upon this looking for help. The Ubuntu Folding@Home Team does have it's own IRC channel!! It's up and running strong again, and hopefully it can be a great resource for those looking for help getting F@H setup, or troubleshooting any issues you may be having. If nothing else, come hang out and we can shoot the breeze and talk about folding!

So come on by, and check us out on #ubuntu-folding on the FreeNode network! We look forward to seeing you guys there!!

Hi all,
looks like the wiki ( https://help.ubuntu.com/community/FoldingAtHome ) is not up-to-date (see ppa for origami for example... ), can someone update it please?

Which of the install methods you think is the easiest one for a "standard install": laptop with one CPU on Ubuntu 9.04, and i would like to have the possibility to start/stop F@H via a button or command line. If possible i would like also to control which % of the CPU is used by F@H.

thanks in advance for your answers!

Well, you're in luck...

I *just* got done updating quite a bit on the Origami Wiki page (https://help.ubuntu.com/community/FoldingAtHome/origami) so feel free to check it out. I haven't gotten to the main Folding@Home wiki page yet, but I'll work to get it caught up a bit.

As far as which method would be easiest to use, stable, and easy to monitor... that would of course have to be origami :) It's also what I run on my single-core, 9.04 laptop, so if you ever have any issues/questions I may be able to lend some advice.

It takes two commands to install, one command to check your progress, and can be stopped/started by a simple command as well. All of the info you could need is on the wiki page I linked. However, origami has it's own wiki if you'd like to check it out as well:
http://origami.zelut.org/doku.php

As far as having the F@H client only use a certain % of your CPU - I don't know of a way to do that currently. The way the client works is by using your 'spare' processing power. It has very low priority, so any programs, apps, etc. that you run will still receive all the CPU power that they want. Then, whatever power isn't being utilized will go to the F@H client. This way, you won't notice any system lag, lack of power, or any other ill-effects from the F@H client, but it also does as much folding as possible. Since it works this way, it will keep your CPU at 100% no matter what you're currently doing on your computer.

Welcome to the fold, YannBuntu ):P

[YannBuntu]

Thanks a lot, i will test it, and that will help me update the ubuntu-fr wiki too :)

Just a remark: here https://help.ubuntu.com/community/FoldingAtHome/origami#Ubuntu%20PPA%20(.deb) you should remove Dapper and Gutsy as ubuntu desktop is not supported any more for thoses versions. Also you could add Jaunty (and Karmic) if there are PPA..

[jpkotta]

...should remove Dapper and Gutsy as ubuntu desktop is not supported any more for thoses versions...

Dapper server is supported until June 1, 2011. I think Gutsy is completely unsupported.

@all: some questions:
- with origami, how can I start/stop the folding process? (i think it is possible with the "finstall" F@H installer (https://help.ubuntu.com/community/FoldingAtHome/finstall))
- how can I add/remove origami from the "applications that start at the beginning of my session"?
- is it possible to limit the CPU used by origami ? (i don't want my laptop fan to be too noisy)

I think these informations should be in the wiki...

other question: is the the "finstall" F@H installer (https://help.ubuntu.com/community/FoldingAtHome/finstall) still working on Ubuntu 9.04 ? (last update of the wiki was in June 2008...)

@jpkotta: you are right! :)

[swoody]

@all: some questions:
- with origami, how can I start/stop the folding process?
sudo origami stop
and
sudo origami start

- how can I add/remove origami from the "applications that start at the beginning of my session"?
Origami auto-starts by itself on bootup. However, there has been a conflict between the usplash used in Jaunty and several programs which auto-start by default (origami being one of them). This is still being tested with 9.10, but it appears that this will no longer be an issue. For the time being, you can either run:
sudo origami start
to start origami after bootup, or disable usplash. There have been users who have reported that by removing usplash several of their programs that are set to auto-start worked as they should.

- is it possible to limit the CPU used by origami ? (i don't want my laptop fan to be too noisy)
No, I don't believe there is. If there is something available to do this, it would be a third-party app, and I do not know of any offhand. If you have a multi-core CPU, you should be able to limit the program to only one core, and this would effectively reduce your CPU usage to 50% (on a dual-core).

I think these informations should be in the wiki...
You raise a very good point here. I will make a note to include more info on how to stop/start origami, as well as a section for FAQ.

other question: is the the "finstall" F@H installer (https://help.ubuntu.com/community/FoldingAtHome/finstall) still working on Ubuntu 9.04 ? (last update of the wiki was in June 2008...)
I believe it is still functional under Jaunty. I tried it out fairly recently, and I don't recall encountering any issues.

[jpkotta]

- is it possible to limit the CPU used by origami ? (i don't want my laptop fan to be too noisy)

Now that I think about it, there is a note in the wiki about this. https://help.ubuntu.com/community/FoldingAtHome#cpulimit

However, F@H should run at a low enough priority that it should not kick up the frequency of your CPU. In my experience, even at 100% CPU usage, the fan is not needed at the lowest frequency. You should verify that you have frequency scaling enabled, and that F@H is not kicking it up.

Thanks a lot for your quick answers! :KS
