A small script to view the CPU topology on a machine. Running ./cpu-topology.py will give a breakdown based on socket, NUMA node, core, and hardware thread on the current machine.
Sometimes it's useful to pin processes to specific cores; one way to do it is by placing the proesses as "far away" as possible. In this case, you continuously alternate between sockets, nodes, cores and threads.
Another one is to place them as close together as possible. In this case, you completely fill each hardware thread, core, node, and socket, before proceeding to the next.
When a machine has many cores, it's often tedious to make such a mapping by hand. You can generate such an affiniy mapping by running "./cpu-topology.py scatter|compact"
