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.
