Get or set a process' CPU affinity or start a new process with a defined CPU affinity. More information: https://manned.org/taskset.

• Get a running process' CPU affinity by PID:

taskset {{[-p|--pid]}} {{[-c|--cpu-list]}} {{pid}}

• Set a running process' CPU affinity by PID:

taskset {{[-p|--pid]}} {{[-c|--cpu-list]}} {{cpu_id}} {{pid}}

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

taskset {{[-c|--cpu-list]}} {{cpu_id}} {{command}}

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

taskset {{[-c|--cpu-list]}} {{cpu_id_1}},{{cpu_id_2}},{{cpu_id_3}}

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

taskset {{[-c|--cpu-list]}} {{cpu_id_1}}-{{cpu_id_4}}
