Why wont my CPU fold right !?! - Page 2

post #11 of 54
-smp 7 would only let it use 7 of the 8 threads, thereby freeing up a core for the GPUs to run, which is an important thing for Fermi folding. Also, it looks to me like you have the -bigadv box checked.

Unless I'm missing something.

that person is not OP

Do you have to set it to use ALL 8 cores to take advantage of -bigadv ??

Ah, so I am missing something then, lol.

Anyhow, to OP, freeing up the core would most likely solve your problem, as Fermi folding does take up CPU power. It's nice to leave the core free anyways, I always got better PPD with -smp 7 than I did 8.

I'm not all that familiar with client v7, the machine I use for science is currently offline, so take that with a grain of salt.
Damn!

GPU folding depends on some CPU power, even worse when folding with Fermi. It is recommended that you dedicate one tread per GPU client when using Fermi. Besides that, you probably dont have enough ram, -bigadv uses about a GB per thread, so to allocate that and all the GPU clients must be stressing for the ram, that's why you get low PPD on the CPU

You need to give it a couple of frames to see the changes. It won't show up instantly. PPD calculation usually goes off the average time of the last three frames, so you might need to wait an hour and a half or so to see a difference if you're running a -bigadv.

No it doesn't. It uses about 1GB for the client.

Oh really with bigadv? I have 12GB of RAM on my work machine. This has potential....

With 7 cores/threads, I appear to be only getting about 700ppd more. Given, the SMP is still yellow for the points. I should probably let it keep configuring?

My total combined PPD with an Core i7 940 (stock) and GTX560 Ti is 16,951.
