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}
