SCHED_ULE(4) BSD Kernel Interfaces Manual SCHED_ULE(4)NAME
sched_ule — ULE scheduler
SYNOPSIS
options SCHED_ULEDESCRIPTION
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.
