2x GPU2 Clients running on 1 GPU

post #1 of 36
Thread Starter 
I have seen a couple of post where folders are claiming to be running 2 GPU2 clients on 1 GPU... This does not seem right to me.

Is it possible?
Is there a benefit?
How do you it (if possible)?
What would the team comp rules say about it?

It would be nice for HD48xx users maybe then they could use 640 of their 800sp (2x320).

Are you sure they weren't saying they were folding on 2 different cards? (sli)

It's completely possible, I have done it. There was no benefit at all. I would just wait for the next GPU2 client that supports multi-GPUs.

In a related question (I am new to GPU2) is there a way toFold on all 4 of the cores in my sig rig GFX? I read the info on the Stanford site but didn't quite get it...something about extending desktop by using a second monitor...but that's doesn't work in Xfire anyway...

Your can still run SMP while running GPU2! Hell on that Skulltrail system of yours, you can run 4x SMPs and two or more GPU2s!

You would think...but unless I juggle the priorities a little it doesnot do well at all. the SMPclient is stuck on the 2665 work units and they are taking FORever...tying up 100% of the CPUs...to get the GPU client to run at a decent rate I adjusted CPU usage/priority and it was better.

I run two SMP clients and one GPU client but if I could be more productive to the science by running all GPU I would...I just am not sure how...

sorry for the huge picture. Goes to show what they mean by extending display to use the second card. I wish I had the funds for a second monitor

If you could chop out the right side of that and zoom in on what we need that would be great...

I was actually thinking about your rig the other day and how crazy it would be to tweak it to use the GPU2 clients and smp client. If I'm correct you have 4 PCI express slots right?
