How to limit Thread for IntelCPu with HyperThreading

[GoogleCodeExporter]

I read : 
{
          GPU performance is reduced on system with Hyper Threading

       NVidia/ATI GPU driver requires at least one real core per GPU for efficient work. With HT enabled driver needs to fight for CPU cycles with CPU computing core. This leads to GPU starvation and decreased performance. The problem can be solved by reducing number of running CPU-Cores

}

SO
How to réducing thread, or limit core for ce CPU ??

My configuration : 
Pyrit 0.4.0 (C) 2008-2011 Lukas Lueg http://pyrit.googlecode.com
This code is distributed under the GNU General Public License v3+

The following cores seem available...
#1:  'CUDA-Device #1 'GeForce GT 425M''
#2:  'CPU-Core (SSE2)'
#3:  'CPU-Core (SSE2)'
#4:  'CPU-Core (SSE2)'
#5:  'CPU-Core (SSE2)'
#6:  'CPU-Core (SSE2)'
#7:  'CPU-Core (SSE2)'
#8:  'CPU-Core (SSE2)'
#9:  'Network-Clients'

i wouldlike to have 6 thread CPU max 

thank you

as answered on the Wiki: use .pyrit/config to set limit_ncpus to 6
