Howto setup Folding@Home

[meander]

strange, i installed without sudo, and all went well until i tried to start it, which gives me:

~/fah_install$ start-stop-daemon: Unable to open pidfile `/var/tmp/FAH502-Linux.exe-1.pid' for writing: Permission denied (Permission denied)

Please post the results of the following command:

ls -ld /var/tmp

If that command doesn't work as a user, then run it with sudo.

Excellent Post told me exactly what i needed to do.

Thanx.

So what is the deal, is this going to clog up my system now? I thought this was just something that would use my cpu when the screensaver turned on?

Dare i ask if it would be possible to change the folder it installs to? I dual boot XP on here and would like the two OS's to have access to the same work files instead of doing their own thing.

I tried to figure things out on my own but this isn't exactly a simple batch file we have here. The other FAH install is on a mounted FAT32 drive. "/media/bigpart/fah"

You can't work cross platform in FAH. GO to the actual FAH forums if you want info on FAH on dual-boot systems. If you don't spend a significant amount of time on both OSs, you need to turn timeless WUs on at least the one you spend less time in.

FAH runs all the time, not just when the screensaver runs. It runs at a very low priority, so you should never feel an impact (other than memory usage, but you can control that).

I was going to add this to the wiki page, but for some reason I can't edit anything in the wiki.

The Windows console client works in Wine, so you can run cross platform.

If you use the installer script from the wiki, you can just install as usual, and after installation:

1. move /opt/foldingathome to whatever you want
2. change the line "fah_dir=/opt/foldingathome" in the script /etc/init.d/foldingathome to point to whereever you moved it
3. change the line that looks like "executable=FAH502-Linux.exe" to have the name of the windows client (or rename the windows client)
4. change any lines that look like "--exec $client_dir/$executable" to "--exec wine $client_dir/$executable"

Disclaimer: I have no idea if this will actually work, but it should be at least a step in the right direction. You can always write your own init script too.


Also, I'd bet that the Linux client runs in Cygwin.

Okay, in need of a little help. I was able to set this up before but for some reason cannot get it to work now. I go thru the steps and extract the folder to home/sleepy127/folding and in that file is the fah install folder. I get to step 4 and I get a command not found error. I try to double click the folding install file and choose run in terminal and terminal pops up and closes immediately. If I choose to run it it does nothing. I can not figure out what I am doing wrong.

This is the last command that I tried. I modified the original command thinking that maybe it was not specific to my install and I received the same command not found reply.
sudo ./folding/folding_install.sh install

The directory that gets created is fah_install, not folding. You can see what files (and directories) are in the current directory with the "ls" command (ls = LiSt). Look here for more than you ever wanted to know about the command line and Unix/Linux in general.
