My System Specs

Default

I use WinAFC 0.92 with a fair bit of success.

There are two approaches to this whole GPU/CPU co-existence scenario:

1) Allow CPU affinity changes by running the SMP client with the -configonly flag and selecting "yes" when it asks to allow CPU affinity changes
2) Use an affinity changer to lock all GPU clients to one core, and preferably a PHYSICAL core with Core I7 (920/980x)
3) Run the -smp (n-1) flag with n being number of cores/threads, so -smp 11 for Core I7 980x or -smp 7 for Core I7 920/860 and lock all GPU clients to the unused (by SMP) core either physical or HT.

Right now my Core I7 980x @ 4.05 Ghz is getting over 50K on a P2685 with three GPU clients running using the WinAFC setup to lock all GPU clients to a physical core.

But yes, I notice my Phenom II X6 or my Opteron (24-core) duallie box see less slow down with multi, or single GPU clients running simultaneously with SMP. I guess real cores seem to make some differences.

I can get around 15k ppd out of a P2685 w/ my i7 920 @ 4.2GHz and three GPU3 clients. And this is setting affinity for nearly all major processes running.

I guess I should have done some research on how much GPU clients can affect SMP A3 WUs before going out and spending $1000 on the cards & water blocks.

Ouch, tell me that the watercooling is on your main PC at least..

It is. I was just hoping for my PPD out of the money I spent.

I use two 285s in a 3.8GHZ system and I get 25k on that project lowfat.

I use prifinity to set the processes. Set the GPU processes to 'high', and the a3 process to 'above' and see if that helps.

Do you use the machine all the time as well? This is my main gaming, PVR, media, and file server machine. It has 90 processes going 24/7 and 20 HDD/SSD's hooked up to it. I think this is likely the biggest reason I can't get good ppd out of my SMP client. W/ the GPU clients shut off it can do about 30k ppd w/ just the SMP bigadv going. If may also be a GPU3 thing. Each client takes 3-8% CPU usage. I also can't increase the priority of the SMP client as watching TV is impossible due to stuttering.

I don't think tge GPU3 clients are the culprit, but each case is differents of course. In my case, my main rig when I'm not using it (980x @ 4,4 ghz with 2X GTX 460) is doing about 52 000 ppd for the newest -bigadv (ex 2685, 2692) and 21 000 ppd for the 2X GPU 3 clients.

If I do some gaming or web surfing, it is always the windows SMP -bigadv client that drop in PPD, never does the GPU. (Well I don't game very extensive GPU game I must say... ex: Heroes of Might and Magic 5) And thats is where it hurts, when it drop, it drop of 15 000ppd when I'm using it. So like it was said before -bigadv unit points are really base on bonus point, so a slight decrease in TPF means a lot less points.

So if your main computer have always 90+ process running, it is sure that it will hurts! In my case just web surfing does hurt! Maybe try it a couple hours totally dedicaded to FAH to see the PPD diff.
