SCHED_ULE(4) Kernel Interfaces Manual SCHED_ULE(4) 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 fea- tures 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. AUTHORS Jeff Roberson <jeff@FreeBSD.org> FreeBSD ports 15.quarterly August 10, 2012 SCHED_ULE(4)
