How Do I Install Mprime?

[He's Dead Jim]

hi everyone..

i am trying to install mprime which is the linux version of the prime95 stress test, and i have no idea how...

i just completed my first successful installation of ubuntu and i need to run this test overnight..

i don't know anything about linux other than the installation, and although i downloaded the free pdf for the pocket guide, i need to set this up in the next half hour and i can't read that fast...lol..

any ideas??

thanks..

[Paqman]

Hmm, looks complicated. Do you actually need this particular app, or will any stress tester do?

[He's Dead Jim]

anything that will stress out the processor and possibly the memory would be great....

thanks...

:)

BOINC/Seti@home? It's in the repos, and you'd be doing something useful at the same time.

You could also run, for example, Gaussian elimination in linpack in some infinite loops http://en.wikipedia.org/wiki/LINPACK . But BOINC attached to some project must be the easiest way as everything's in the repos.

[He's Dead Jim]

thanks for the quick replies....

i downloaded the boinc program from berkely, but how do i get it to run??

thanks...

I am currently running Prime95 on a new set-up and installation is not required. Simply download the tarball from http://mersenneforum.org/gimps/mprime259.tar.gz

Extract the contents to a folder of your choice or create one specifically for Prime95. Navigate to this folder and open a terminal and execute this command "./mprime".
It should ask you a few questions as to how to torture test your computer and away you go.

wow, that was super easy...

thanks..

mprime is running nicely now...

what is the linux version of a batch file?

[MooPi]

Now that is a loaded question. Linux scripts or executable text files are a basic function of linux and this is how most of what I do on my computer functions. Learn your basic terminal commands and then read about #!/bin/bash scripting and the world of Linux will open up to you. If you look at the screenshot I provided you can see a broken script on the lower panel. It's the little red X on the lower right hand. Recently updated my Firefox browser and for some reason it broke my desktop script Icon. I will simply open the script with gedit and correct the icon change.

You cooould do it that way, but it's always better to get your software from the repos. Go to System > Admin > Synaptic and browse in wonder at the tens of thousands of packages available for immediate installation!

[He's Dead Jim]

thanks again you two....

looks like this is gonna be a fun ride....

i'm still used to win-doze double click stuff, but if i could quit smoking after 30 years, i can learn linux...

Go to the phoronix web site and gaze in wonder at the magnificent test suite... :)

http://www.phoronix.com/scan.php?page=article&item=pts_22_bardu&num=1

It is probably far more than you need.

Sorry Paqman, I couldn't resist... :)

[egalvan]

MooPi, where did that gorgeous back-ground come from?

good stuff...

i was originally given that link by a friend, but chose mprime because i just need to load down the cpu while i run a 8 or 10 hour latency test.....

thanks much though....

[MooPi]

Thats from the National Geographic. I actually don't like that one much. It just happened to be up when I was responding.
If your looking for a benchmark test that will bench your Mac , Windows and Linux computer try Geekbench from Primate Labs.. It's how I measure mine.

[Joel Barnes]

Does anyone know why this is happening? I haven't had a problem running any other executables, and I had plenty of practice trying to get the ******* lm-sensors working. I've rebooted since downloading it, and I've tried to run the executable in the gui as well - no error, no execution. The readme lists a lot of files not in that dir, but I've downloaded the .gz from a few targets and they are all the same file. And my file list looks like a screenshot someone else posted here. I'm stumped.

Joel, I'm a bit of a novice myself when it comes to Linux, but let me see if I can help.

First of all, the correct command in this case is would be one of the following:
./mprime
./mprime -t
The second example is used if you want to go straight to the torture test mode.

Second, the extra files that the readme talks about are temp files that mprime will create while it is running to save the work units in between shutdowns of mprime.

Third, are you sure you got the correct version for your machine? For example, this isn't a 64-bit executable on a 32-bit version of Ubuntu?

[Joel Barnes]

Yes, the problem was the executable version. I was trying to run the 32-bit on a 64-bit system.

Thanks,
Joel

I dunno why folks discourage people from learning anything about the terminal. The learning curve involved is pretty much what separates normal windows users from a typical linux poweruser.

Seriously, the terminal is the best thing in the world. It's so damned powerful. Having that much control over your software is intoxicating.

I like using the terminal so much (because it looks pimp to everyone watching you use your computer) that I installed DOSbox for kicks so I could learn new old windows commands (and play non-ported and old games).

edit: besides, mprime/prime95 is not available on synaptic, at least I couldn't find it

Install and autostart MPrime on Ubuntu 11.04 Natty (Desktop or Server)
with crontab autostart 'bootup script'

After some years I tried again to launch MPrime using the autostart bootup start-script by Gareth Randall, Sun, 12 Nov 2000, originally posted on a mailing list archive, here: http://www.mail-archive.com/mersenne.../msg05245.html (http://www.mail-archive.com/mersenne@base.com/msg05245.html) , as I did in former years.

Since I run Ubuntu Natty 11.04 on my AMD Fusion E-350 (http://en.wikipedia.org/wiki/AMD_Fusion) computer, Upstart (http://en.wikipedia.org/wiki/Upstart)(http://upstart.ubuntu.com/getting-started.html) has replaced the former /etc/init.d method. So I got the error message:

su: must be run from a terminalwhen using the startup script by Gareth Randall, see above.

Here's the steps I followed to achieve the installation and bootup / autostart of MPrime on my Ubuntu Natty 11.04 driven PC:
----------------------------------------------------------

0) On the terminal I created the folder /gimps:
master_and_commander@1stcomputer:~$ mkdir /home/master_and_commander/gimps
### Hints:
# path of mprime-binary in Ubuntu then is: /home/master_and_commander/gimps/
###1) Downloaded and extracted mprime266-linux64.tar.gz (or whatever the appropriate version is) from www.mersenne.org (http://www.mersenne.org/) to the ~/gimps folder.

1st the 64bit variant:

master_and_commander@1stcomputer:~$ cd ~/gimps
master_and_commander@1stcomputer:~/gimps$ wget ftp://mersenne.org/gimps/mprime266-linux64.tar.gz
...

whatsnew.txt
master_and_commander@1stcomputer:~/gimps$
2nd the 32bit variant:

master_and_commander@1stcomputer:~$ cd ~/gimps
master_and_commander@1stcomputer:~/gimps$ wget ftp://mersenne.org/gimps/mprime266.tar.gz
...

license.txt
mprime
readme.txt
stress.txt
undoc.txt
whatsnew.txt
master_and_commander@1stcomputer:~/gimps$
2) In the terminal changed to this directory and run the ./mprime -m from xterm to set up the preferences by the MPrime menu:
master_and_commander@1stcomputer:~$ cd ~/gimps
master_and_commander@1stcomputer:~/gimps$ ./mprime -m

Your choice: 3) Now I used cron to have MPrime autorun in the background at start up boottime. See
https://help.ubuntu.com/community/CronHowto

master_and_commander@1stcomputer:~$ cd gimps
master_and_commander@1stcomputer:~/gimps$ crontab -e

Select an editor. To change later, run 'select-editor'.
1. /bin/ed
2. /bin/nano <---- easiest
3. /usr/bin/vim.tiny

Choose 1-3 [2]: _



Accept [2] with <RETURN>.
You will see the editor "nano" displaying the content of your crontab file:

Here, directly, type in the following line, save with <Strg-O> and close the editor with <Strg-X>

@reboot /home/master_and_commander/gimps/mprime &
Hints:
"@reboot" at every bootup ..
do " /home/master_and_commander/gimps/mprime &", that is in the bash shell, start mprime program-code " /home/master_and_commander/gimps/mprime" ..
and run it in the bachground ("&") , tht is without any output at stdout (=terminal window).

Otherwise try this command-line:

master_and_commander@1stcomputer:~$ echo "@reboot /home/master_und_commander/gimps/mprime & " | crontab -
[sudo] password for master_and_commander:
