Setting up the MultiGPU Folding Client

post #1 of 9
Thread Starter 
I've got the basics down, but are there any advanced settings I should consider when setting this up?

I'm also planning on rolling back my ATI drivers to 6.5. Apparently those are the most optimized drivers going for the GPU clients. Any advice here would be appreciated. I want to make sur eI'm making the most of the x1900s.

TIA

They have a lot of info over in the stanford forum. I would suggest taking a look in their gpu section.

I agree with checking the Stanford forums for answers to any questions you might have.

Heat was my issue with folding, one card sucking up the warm air of the card below and just a general rise in case temperature of about 25°C.

The thing I can't figure out is where you specify the GPU ID in the client.

Anyone know where you do this?

Edit - Well here's what I wound up trying:

I'm running one client with a flag of -gpu 0 and another client with -gpu 3. I'm pretty sure I specified this in the correct area. Both clients are now running - I didn't receive any error or conflict messages. I guess I just cant confirm that one client is using one GPU and the other client is using the second GPU. How can you check to see and make sure that it's setup properly?

If it is running without errors, just watch time times and see if the are working as you assume they should. You can monitor them with FAHmon as well. The -gpu switches you are using are correct, so most likely, you should be ok.

The folding support forums have been down for the past day, so it is hard to find better documentation on what you are doing at the moment.

Thanks, knite. Theyve been running for about 3 or 4 hours now. I started them at about the same time - one client is about 17% done and the other only 11% Makes me wonder whats happening in the background I guess. I didn't bother to check the voltages with ATI tool with them though. I should probably do that because I don't think theyre automatically set at 1.4, which the F@H site recommends. I'll keep toying around.

Now since I'm running two clients, what does this count as exactly? One "core" or two? I'm just wondering how it works out with my folding team I'm on.

For the sake of the folding team competition, you should count dual GPUs as two towards the core limit.

So after 24 hours of having two GPU clients running, one of them managed to finish and start up on the next one, while the second client was lagging a little behind at only around 70% completed after 24 hours. Is that normal?? Could it just be a particular WU that's making it take longer?

Also, is it a good idea to run the SMP client along side two GPU clients?? I figure I'd have to adjust the CPU usage for one of them...Just looking for a little advice.

Thanks for the help guys!
