Module runtime 

The bits of RUNTIME_OPTIONS: what a scheduler asks of the runtime’s topology, idle scans and clock, rather than of its own policy.

Constants

DISABLE_NUMA

Make the machine one node.

DISABLE_SMT

Make every CID a core of its own, so that nothing prefers whole idle cores or ranks siblings.

NO_TASK_CLOCK

The task clock is the rq clock: charge wall time.

SMT_ASYM_PACKING

Rank the threads of a core by CPU number.

SMT_WHOLE_CORE

A whole idle core anywhere wins over a busy core’s idle sibling.
