numactl

Control NUMA policy for processes or shared memory. More information: https://man7.org/linux/man-pages/man8/numactl.8.html.

  • Run a command on node 0 with memory allocated on node 0 and 1:

numactl --cpunodebind={{0}} --membind={{0,1}} -- {{command}} {{command_arguments}}

  • Run a command on CPUs (cores) 0-4 and 8-12 of the current cpuset:

numactl --physcpubind={{+0-4,8-12}} -- {{command}} {{command_arguments}}

  • Run a command with its memory interleaved on all CPUs:

numactl --interleave={{all}} -- {{command}} {{command_arguments}}
