Process affinity

Here is how to bind a program to a CPU (process affinity):

Bind processes to a CPU core

An example would be:

taskset -pc 0,1,2 20509

to set processid #20509 to have affinity (bind) on Cpu0, Cpu1, and Cpu2. To bind it to a single core, use the command:

taskset -pc 0 20509

to bind it to Cpu0.
