setting affinity in ubuntu

post #1 of 2
Thread Starter 
I have the SP client and GPU client installed and working in ubuntu 10.4.

I have tried to use taskset to lock SMP to threads 0-6, leaving the last for the GPU client.

I can get 23k on SMP with only 7 threads, So if use the 8th for the cpu cycles that the GPU client uses i won't take suck a hard hit on my SMP client.

I can't get the SMP process to stay on the specified thread, It keeps bouncing the process from 2 cores:1 and 2.

Does anyone know how i can lock the SMP down to only threads 1-7???

GPU folding in linux sucks. Windows is for GPU and linux is for SMP. To use both I would run a VM in windows with linux for SMP and then you can fold GPU with normal GPU PPD in windows. The SMP PPD will be a little lower than when running in native linux but overall your PPD will be much higher.
