how to set CPU affinity of a program?
.net, affinity, c#, cpu, visual-studio-2008
Solution
- Go to Task Manager -> Processes tab.
- Look for your program. Right click on it.
- Select Set Affinity and uncheck one of the checkboxes.
This should free up one processor for you.
For doing it from the code you can add this statement:
System.Diagnostics.Process.GetCurrentProcess().ProcessorAffinity = (System.IntPtr) 1;
Cheers!
Problem
I have a program written in C#, I am using VSTS 2008 + .Net 3.5 + Windows Vista Enterprise x86 to develop a Windows Forms application. My current computer is dual-core CPU, I want to set CPU affinity of my program to run on a specific CPU and free another CPU to do some other job. Any ideas how to do this? Either through coding or configuration is ok. A little more background is, my program is CPU intensive, so I do not want to let it occupy all two CPU resources on my computer and I want to free one CPU so that I can browse network at the same time quickly. :-) thanks in advance, George
