SCHED_ULE(4)						   BSD Kernel Interfaces Manual 					      SCHED_ULE(4)

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 interactivity and include: o Thread CPU affinity. o CPU topology awareness, including for hyper-threading. o Per-CPU run queues. o 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.

HISTORY
The sched_ule scheduler first appeared in FreeBSD 5.1.
