sched_ule - ULE Scheduler
.Cd "options SCHED_ULE"
The sched_ule scheduler is an experimental scheduler that provides a number of advanced scheduler features not present in sched_4bsd(4), the default 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. |
The sched_ule scheduler is disabled by default as it is experimental. See the BUGS section for more information.
