JD and Michael,

Take a look at taskset:

  taskset is used to set or retrieve the CPU affinity of a running
  process given its PID or to launch a new COMMAND with a given CPU
  affinity.  CPU affinity is a scheduler property that "bonds" a
  process to a given set of CPUs on the system.  The Linux scheduler
  will honor the given CPU affinity and the process will not run on
  any other CPUs.
