NAME

sched_ule — ULE scheduler

SYNOPSIS

options SCHED_ULE

DESCRIPTION

The sched_ule scheduler provides a number of advanced scheduler features not present in sched_4bsd(4), the traditional system scheduler. These features address SMP and interactiv‐ ity and include: · Thread CPU affinity. · CPU topology awareness, including for hyper-threading. · Per-CPU run queues. · Interactivity heuristics that detect interactive applications and schedules them preferentially under high load. The following sysctls are relevant to the operation of sched_ule: kern.sched.name This read-only sysctl reports the name of the active scheduler. kern.sched.quantum This read-write sysctl reports or sets the length of the quantum (in micro-seconds) granted to a thread.

SEE ALSO

sched_4bsd(4), sysctl(8)

HISTORY

The sched_ule scheduler first appeared in FreeBSD 5.1.
