GPU Folding Natively in Linux

post #1 of 57
Thread Starter 


So far so good. I just added the gpu slot, set the client-type advanced flag and away it went. As you can see I'm using the 310.44 driver. I did upgrade to the 3.9.5 kernel.

Nice!

I just too started GPU folding in native Linux, my 560Ti pumps out 22k PPD on 8900. Probably not gonna continue on that card though, my SMP plummet down from 28k to 12k, a gain on 6k PPD for an extra 110-120W isn't worth it 24/7. I'm looking at getting a 780 which have a good price/performance ratio compared to Titan, 20-30k less and 70% the price of a Titan.

Is that all you need to do for it? I have a gt240 laying around I've been thinking of doing it with. Not sure if it'd do better then the athlon II have that gets about 6k ppd.

I'm not sure but here is how it worked for me. I was first trying to get it setup in wine so I followed the wine setup guide here http://www.overclock.net/t/746438/ubuntu-setting-up-the-gpu-client. It was no help since I am using Linux Mint. Yes everything is basically the same but I could not get it to work in wine, kept getting a gpu_memtest_error. So I started updating stuff and thought that I would only be able to fold in windows. First I downloaded the nvidia toolkit from here https://developer.nvidia.com/cuda-toolkit I got version 5 for 64 bit systems since my Mint is 64 bit. I then upgraded to the 3.9.5 kernel. http://latestlinuxupdates.com/linux-kernel-3-9-5/ It was then just adding the slot, set the client-type advanced and there it went. Usually it would reject the core and fail. It's successfully done 1 WU so far.

I do have one issue though, In my system monitor, it shows that the process FahCore_a3 for the cpu folding, is only using about 50% of the cpu but in the resources tab, all 6 cpu's are running at 100%. The folding time reflects the 50% ulilization. Any ideas to fix this? I've tried changing the priority but no luck.

Thanks for that I will have to try it out. Not sure where the system resource gets it from but maybe try running the command top and see if it says the same thing.

I noticed around 1k PPD more in Linux vs Windows on my little GTX 560ti 448 core. 

post #8 of 57
Thread Starter 
I've noticed the same 1k gain. I do have to start the client manually in a terminal and if I want to use FAHControl, I then have to start it. FAHControl does not automatically start the client as in Windows. I restarted the client and FAHControl and it is now running 86% for the Fahcore A3 and 14% for the gpu 17 core. All is well, the cpu folding times have gone back to around 12 minutes. In Windows it was around 14 minutes. The gpu folds are about 15 minutes on my 460 gtx. Now to overclock back to 4 ghz. Also, the electricity usage is of little concern since its included in my rent. I have actually been using my computer to regulate the temp in myroom since it usually stays really cold.

So I'm interested trying Mint. What parts didn't work from the guide?

I've burned the ISO onto my USB and have CUDA 5.5, GPU drivers, FAH and 3.10 kernel (I think) on my c:\temp ready. Besides right now not knowing how to execute any of them, did you follow the guide otherwise.. or?

Add: so this was a failure. FAH installed ok and SMP went well, but nothing else worked. None of those "packages" installed, it's running very old kernel and the GPU slots kept failing. If someone can update install methods would be appreciated...

I think you have to install mint on your hard drive and not run it off your flash drive. There should be an icon on your desktop for that. before you do, make a partition for it. do the advanced install option and put it on the new partition. this way if you break it, you can just format and start over. do not chance the grub location. with the packages you downloaded, just right click, open with, package manager. you don't have to download any video drivers, just use the recommended one. Also, the website where you get the packages should have install instructions.
