Process ProcessThread Thread

Process

ProcessThread:

Process and ProcessThread objects have a ProcessorAffinity property of IntPtr type that can be directly manipulated to read/change affinity for up to 64 processors:



using System.Diagnostics;

...

  Process Proc = Process.GetCurrentProcess();

  long AffinityMask = (long)Proc.ProcessorAffinity;

  AffinityMask &= 0x000F; // use only any of the first 4 available processors

  Proc.ProcessorAffinity = (IntPtr)AffinityMask;

  ProcessThread Thread = Proc.Threads[0];

  AffinityMask = 0x0002; // use only the second processor, despite availability

  Thread.ProcessorAffinity = (IntPtr)AffinityMask;

...

You can also use the thread's IdealProcessor property to allow the scheduler to prefer running the thread on a specified processor (without guarantee).
