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.
