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:

              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.
