HD 6870 GPU folding - a couple questions

post #1 of 6
Thread Starter 
I was looking into GPU folding the other day, even though I have an ATI card I thought I might be able to squeeze a few extra points if I could use my GPU to fold also, since I have no need to use it while my machine is at home folding and I am at work, however a couple things came up, and now I am wondering if it is even worth it to fold on my GPU;

-In Process Explorer my kernel access went crazy when the GPU was folding, it slowed my CPU folding heavy. I remember reading something about disabling a CPU core, but what I read did not indicate how I do that. Can I just give up a thread instead of a whole core? Is it just a matter of adding a -flag tothe SMP shortcut?

-I am folding 8 cores @ 4.20 GHz now, this current -bigadv job has been running 24/7 for the last 2 days, iirc my PPD was like 38k or something (at work now so can't recal exactly) would it even be worth giving up a whole core on my CPU just so I can fold on a GPU that would give me less than if I had all the cores on my CPU?

-There did not seem to be an easy way to watch my GPU folding progress, am I missing something? All I want is a basic window like the smp client to keep an eye on it, nothing special.

Thanks for any help you can give me...

Use the console client (for GPU's) or something like HFM.NET.
I really don't recommend you fold on your video card until the new client comes out (within 3 months or so).

that is the client console that will give you the same basic window that the SMP client enjoys thumb.gif

You'll get more PPD without the GPU at the moment though; running -bigadv needs as much CPU time to maximise points - ATi GPU's also need a lot of CPU time, and the tradeoff is usually detrimental to the SMP points total

Thanks, that's what I was thinking, since I know the 6800's and above are not officially supported yet, but using the flag for the 5xxx did seem to work. my -bigadv will be done in a few hours, so I can do a little testing on a regular WU tonight. I just wanted to know and go through the process for disabling a core/thread and enabling the GPU to kick in and fold, and to see what kind of PPD my GPU would be able to get.

Ah, then you'll need to use the -smp 7 flag. This will tell your bigadv to use 7 out of 8 cores, and leave one free for the GPU client

It isn't worth doing -smp 7 if you are folding bigadvs to add in a ATI GPU. frown.gif
Just wait a while, hopefully the new client is released in Q1 like the rumors say.
