taskset

Get or set a process' CPU affinity or start a new process with a defined CPU affinity.

  • Get a running process' CPU affinity by PID:

taskset --pid --cpu-list {{pid}}

  • Set a running process' CPU affinity by PID:

taskset --pid --cpu-list {{cpu_id}} {{pid}}

  • Start a new process with affinity for a single CPU:

taskset --cpu-list {{cpu_id}} {{command}}

  • Start a new process with affinity for multiple non-sequential CPUs:

taskset --cpu-list {{cpu_id_1}},{{cpu_id_2}},{{cpu_id_3}}

  • Start a new process with affinity for CPUs 1 through 4:

taskset --cpu-list {{cpu_id_1}}-{{cpu_id_4}}
