the Gentoo install is pretty easy.

it was like

emerge -av foldingathome

doublecheck the config in /etc

then

rc-update add foldingathome default

/etc/init.d/foldingathome start

For more Linux fun.

tail -f /opt/foldingathome/client*/FAHlog.txt

tail -f /opt/foldingathome/client*/FAHlog.txt

And so everyone understands the command:
tail means show the last lines of a specific file, standard 10 lines
-f means it has to follow updates of the file

So it basically is a primitive monitor in the console.

I normally use tail -f /var/log/messages too. -f is a keep tailing option.

It seems if you want entries to go to syslog. You'll need to run this script

#!/bin/sh
tail -f logfile | logger -p local4.info

Hi guys,

I'm only a n00b with this folding stuff but I found this guide very easy to setup:

http://smp.aeternum.co.uk/guide/6

I made the jump to Ubuntu Gutsy 64-bit, and it's made a massive difference to my folding. It's pulling in 7040 points every 30 or so hours.

I'm running 4 smp clients on a Q6600.

It's the only thing to convince me that 64-bit is the way to go!

[Stijndp]

Do you mean running 4smp's or one smp and 4threads?

[sc00p]

Hmm... 7040/1760=4 (=SMP-wus)...
...which is really very mind-boggling if that's is done with one q6600 (=16 threads of SMP-client on one cpu ???)

You're saying you get 7040 points on a single processor with four cores every 24 hours. I just want to be certain this is what you are telling us.

Just finished 3 X SMP Gromacs cores @ 1760 points each and the fourth is another SMP Gromacs @ 2315 points- its at 53% at the moment but taking a bit longer than the others. Is the 4th one some sort of special wu?

[sc00p]

Come on man, simple answer would be suitable:

Your CPU count is:
A: 1
B: 2
C: 3
D: 4

if the answer is anything else but the B-D... I'll shoot myself for a various reasons

EDIT: sorry... wrong format...

Never actually answered your question there...

It's been running since last night about 8pm, it's 9pm where I live now and it's completed 3 WU as I said above. The fourth one though I might have jumped the gun with looks like that will be finished in about 48 hours.

OK that's just... well phenomenal is a good word.

I'm cautiously curious about this. Guess I will have to DL a distro and try this on the folding box. And here I just installed XP on it at the beginning of Jan (It had an old Solaris install)

I'm curious as well, judging by the reaction here, 'cos I don't really know how the program works, I followed the guide above and just ran with it- just happened to be testing a 64bit OS to make sure it runs without any hitches before I get some more ram to make use of it.

Just had a look at the system processes and it's running 4 threads per core.

I am going to have to check this out. I find it hard to believe that it's twice as fast as a quad on 32 bit XP Pro. I have a rig with 64 bit XP Pro I might try it on. Do you think that Linux 64 will be better than XP 64?

[Stijndp]

Well it might be possible if it's double gromac b. Here is the benchmark from my E6750@3.2GHz, it runs two console clients and the benchmark isn't bugged because these things go really fast.

4200ppd on E6750 @3.2 versus 7040points in 30 hours on a Q6600 @2.4 seems very normal to me. If you take the calculator and start counting you see the normal extra performance linux gives.

[[XC] 4X4N]

Damn, that's more than I get with my quad at 3.5. I'm a linux noob, but I'm going to try and see If I can do this. If it does wu's twice as fast, thats all good.

[[XC] 4X4N]

OK, I have linux going now with the smp client, will see how it goes. But I couldn't get fahmon to work, any pointers on that? Also, how about some hardware monitoring like core temp, or everest? And maybe something like cpu-z.

[Stijndp]

gkrellm should have everything you need.
There are also some real cpu-z clones but you should be able to find them fast with google.

For Fahmon it's best you use the Documentation. We can't help much with unspecified problems

Which distro are you using?

If it's ubuntu you can run this in the terminal:

sudo apt-get install lm-sensors

It's fairly easy to setup after it's installed- again in the terminal run sensors-detect and answer yes to all the questions.

You can then install Gnome Hardware sensors monitor and select which sensors you want. I'd also recommend conky, to view various system processes.

FAHmon was straight forward enough, Again I followed this guide:

http://smp.aeternum.co.uk/guide/7

After installing it right click underneath the progress and name headings in the top left corner and select add new client and then select your folding folder.

I've included a screenshot below. Right hand side is conky, at the top right you can see the temp monitors and FAHmon running in the middle

Here is what I get when I try to make install fahmon.

I have tried a few times and this is as far as I get. Going by the guide on the above post.

Also, I used the restricted driver for my 7300gt and now I have no selection for screen resolution above 1024x780. I have searched for a fix for this, but no luck yet.

I had a look at the aclocal directory on my machine and it's rw root and that error looks like a permissions issue. I know it's a stupid question but have you tried running make install as sudo?

[Stijndp]

Or you forget to chmod the directory.

Linux 64 SMP folding rules But 4xSMP clients.. on 1xQuad core machine? Am I reading this right? Must get close to hitting deadline on these WU's running 16 threads on 4 cores?

Linux 64 SMP folding rules But 4xSMP clients.. on 1xQuad core machine? Am I reading this right? Must get close to hitting deadline on these WU's running 16 threads on 4 cores?

I'm planning on running it on the server version for a week. Eye-candy and ffmpeg are starting to play havoc on my stability so it hasn't been folding for a day or two. I'm going to let it finish it's current WU's and then re-install without GDM, Compiz...etc.

It's kept within the deadlines though- with 5 or 6 hours to spare.

[road-runner]

I have run two SMP clients on Ubuntu 7.10 64 bit on a quad at 3850mhz, if I got lucky and got the 2653 WU I could get 5200 PPD according to Fahmon, I was also assigning two cores to each client with taskset...
