pts/namd-1.3.1: add tuning for Linux NUMA systems #308

Closed ColinIanKing closed 5 months ago

ColinIanKing commented 5 months ago

NUMA Linux systems benefit from adding the memory affinity +maffinity option and this won't affect non-NUMA performance. On large multi-CPU systems adding +CmiSleepOnIdle reduces the threaded spinlock impact across shared memory and reduces the jitter of the metrics and also helps NUMA systems too.
