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.

SEE ALSO
     sched_4bsd(4), sysctl(8)

HISTORY
     The sched_ule scheduler first appeared in FreeBSD 5.1.
