SCHED_ULE(4)	       FreeBSD 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.
