Ohhh, thanks so much dmartins Okay I see in the NI column in htop it is indeed at 19 already. So that means low priority right? Just checking, never messed with nice/renice/ionice thanks a lot

Hey Gang,

so far I've been running arch linux for about 6 months now. Not a single problem intill I let F@H run over night. I woke up, I could still hear my comps fans spinning as it usually does when the CPU is under load. But when I sat down my system had completely hanged on me.

So investigating why all of sudden my system is gettin non-responsive I double checked my temperatures. Turned my machine off and let it sit for a few hours before turning back on. Then I let it idle for another 30 mins. here's my temp readings

My GPU running nothing but compiz fusion + gnome is 61 C, and the rest of my temp guages are at 50-56 C.

Not being so much of a hardware guy I'm not sure if these temperatures are good at system idle. But I wanted to ask here if anybody else has had non-responsive systems after running f@h for the better part of the day.

nebri · 2009-04-28 03:47:49

well I increased my fan speed at the bios level, Been watching my temperature sensors like a hawk now and it seems to be doing alright after several hours straight. Hopefully that's all it was.

Zeist · 2009-04-28 06:10:48

50-56C should not be enough for it to completely freeze your computer though, I guess you might have something that has a very low tolerance to heat before shutting down, which at least means that you have a very big margin to the temperatures where stuff would burn.

I am now folding@home at night for Arch thanks to Cron.

I read up on the limitations of my CPU, seems the danger zone begins at 70 C. So I took my machine apart today and found a decent build up of dust on the vents in the casing. Hopefully thats all it was and nothing more.

Congratulations to Natael for reaching the 1 million point milestone! That's quite an accomplishment and I think it's the most exciting milestone to reach.

Cheers!

I just joined the team as well. Right now I only have it on my computer (a 2.4GHz quad core with 9800GTX+), but I have about five other computers I can get my hands on. I tend to break my computer often, but other than that I'll be up 24/7, so hopefully I can contribute something good.

Question, I configured this using the 64bit instructions on page 1, and set the priority to idle, but I'm pretty sure I should switch it to low. That will increase the CPU usage, right? Right now it only uses ~15 - 20% per core. I'm new to all of this, really, all of this. I read on what I think were pages 2 and 3 or so, Pudge said to stop the client and do the rest of the unit with -oneunit option to avoid losing work. What I'm wondering is, how do I stop the client? Will a C-c in the terminal I started it in do it? I don't think the wiki has anything about doing that the non-daemon way. Any help is appreciated, thank you ahead of time!

Sidenote: Hello, Arch community!

Pudge · 2009-06-12 03:46:50

jac;
Welcome to the Arch Linux Folding Team.

Yes Ctrl-C will stop the client if it is running in a terminal window. The only reason you would use the -oneunit option would be if you was going to update to a newer client, or some other special case. You normally don't want the -oneunit option, as it will finish that work unit and not download another. Without the -oneunit option, it just keeps going and going.

I recommend using the idle setting. The cpu usage is low because you have four cores, and that's just the way the SMP client works with 4 cores. On my AMD Phenom 4 core with a 9800GT, I run two SMP clients ( run them in different directories with different Machine ids), and the Windows GPU client through WINE. With a GPU client, your 9800GTX+ would put out about 4000 ppd alone. WIth two SMP clients thrown in, you would get about 7500 to 8000 PPD from your computer from 3 clients. If you are going to do this, make sure you have adequate cooling.

Thank you very much for the information, I did as you suggested and now I have two SMP clients running. I'm going to continue trying to get the GPU client to work, but as of yet I have had no luck.

Meh, I need maor Megahertz!

Not that my position on the team is outstanding right now but still...would like to keep what I have

This assumes you have Arch Linux installed with Xorg and a Desktop environment . In my case I'm using Arch 64 and Gnome. You MUST have a Nvidia CUDA enabled GPU (generally the 8000 series and higher) for this. It also assumes you have 32 bit Wine installed and functional. For 64 bit use bin32-wine from AUR.

If you don't have WINE working, use the Wiki page and proceed through "Create Menu Entries".

http://wiki.archlinux.org/index.php/Wine

Get the Nvidia video driver with cuda installed and working. Use

pacman -Sy nvidia

to install the latest Nvidia drivers from the extra repository. If you have problems, see the Wiki entry for nvidia

http://wiki.archlinux.org/index.php/NVIDIA

Download the WINE wrapper.

In a terminal window as root

wget http://www.gpu2.twomurs.com/wrapper2ndgen/2.1/cudart.dll.so -O /home/username/.wine/drive_c/windows/system32/nvcuda.dll

Of course, change "username" to your user name. Notice that we are downloading cudart.dll.so but saving as nvcuda.dll without the .so A ls -l should report as follows:

$ ls -al  /home/username/.wine/drive_c/windows/system32/nvcuda.dll 

-rwxr-xr-x 1 root root 99101 2009-02-14 02:17 nvcuda.dll

Note the permissions and ownership. If your file does not match, as root use chown and chmod to make it match. This is important.

Download the CUDA toolkit.

Wine and the F@H GPU2 Windows folding client need the 32 bit toolkit, so you MUST download the 32-bit toolkit even if you are using Arch 64 bit. Go to:

http://www.nvidia.com/object/cuda_get.html

Goto "Choose OS" and select "Linux 32-bit" then "Fedora 9"
Goto "Cuda Toolkit: cuda toolkit for Fedora 9" and click "download"

This should download "cudatoolkit_2.1_linux32_fedora9.run" or perhaps something newer.

In a terminal window, navigate to the directory where you downloaded CUDA toolkit. Then, as root

sh  cudatoolkit_2.1_linux32_fedora9.run

When prompted, choose the default installation path by hitting ENTER.

Link the toolkit.

As root

vi /etc/ld.so.conf

add the following line to ld.so.conf
/usr/local/cuda/lib
Then as root:

ldconfig

as user, edit your user's .bashrc file
vi ~/.bashrc
add /usr/local/cuda/bin to your $PATH. If you don't have a PATH statement in .bashrc then:
PATH=$PATH:/usr/local/cuda/bin
If you already have a PATH statement then append the following to whatever is already there
:/usr/local/cuda/bin

Download and install Stanford's Windows 32 bit F@H GPU client.

If you don't have unzip installed, then pacman -Sy unzip

Download and unzip the console version of the GPU2 client. As user:

mkdir ~/.wine/drive_c/folding

wget http://www.stanford.edu/group/pandegroup/folding/release/Folding@home-Win32-GPU_XP-623.zip -O ~/.wine/drive_c/folding

unzip Folding@home-Win32-GPU_XP-623.zip -d  ~/.wine/drive_c/folding

Reboot, then let's see if it works. As User:

cd ~/.wine/drive_c/folding

nice -n 19 wine Folding@home-Win32-GPU.exe -forcegpu nvidia_g80

The GPU2 folding client should start in the configuration mode, then start folding a WU.

Wow! Thank you a lot for all of the information, I was definitely leaving out a few steps, and getting some wrong. I'll test this as soon as I can, but right now the Wine package is outdated and won't work. One way or another, I'm sure I can get your instructions to work. I'll post ASAP about my progress on it, but in the meantime I've managed to add a PS3 to the team.

Just a question, is there something different between the different CUDA toolkits? I had been picking the Ubuntu one, I guess that being the 64-bit version was definitely screwing it up though.

iBertus · 2009-06-14 20:19:29

I'm thinking of joining the F@H effort for Arch Linux but have a few questions. First, I've got a liquid cooled machine w/ two GTX280s and a pair of quad-core Xeon's to work with; I'm willing to use idle cycles to contribute to the F@H effort. I suppose my question is if it's possible to have the GPU folder run only when the machine is idle? Also, can you control the number of CPU cores utilized by the CPU version? I would like to have say 2-CPUs folding at all times and then maybe 7 or 8 during the night when the machine is idle.

whaevr · 2009-06-14 22:05:50

Or you could just use the aur package I setup for GPU clients...

http://aur.archlinux.org/packages.php?ID=23981

It'll download and setup the wrapper and cuda for you..

@ whaever

I forgot about your aur package. That would be another easier alternative.

Ok, so I installed the aur package but what do I do to start folding?

I tried 'wine Folding@home-Win32-GPU.exe -forcegpu nvidia_g80' and this is what I got...

'wine: could not load L"C:\\windows\\system32\\Folding@home-Win32-GPU.exe": Module not found'

Please can anyone help?
My 9800GT is doing nothing for 90% of the day.

EDIT: I now realise I still have to set up wine! I think.

I have it setup as a daemon.

sudo /etc/rc.d/foldingathome-gpu start

If you want to monitor the clients progress I would suggest using fahmon. The folder it will do all its work in is in /opt/fah-gpu/alpha for the first client, bravo for the second and so on..

Thanks for using it!

Hi all,

I now seem to be folding on my 9800GT...

[23:12:40] Folding@Home GPU Core - Beta

I noticed the GPU temperature rise from 65C to 75C within a few minutes.

Anyhow, thanks for the pointer about running F@h as a daemon but I prefer to do some things manually. Hopefully my PPD will shoot up!

EDIT: After around 15 minutes my system hard-locked (very rare). I need some sleep so I will update on what happens later......

Well folding on my gpu does raise its temp for me also. Although my 9800GT idles at 38C and when I fold on it the most I've seen it go up to is 59C

You might want to put better cooling on it if you want to fold on it..I just have the stock cooler on mine, although I have an Antec 900 Case..lotsa fans.
