It can be used to avoid skipping +for A/V-applications, to lock processes onto certain CPUs on SMP/NUMA +systems, or to adjust nice-levels of lesser important jobs to maintain a +high amount of interactive responsiveness under high load. + +All special scheduling classes of the -ck kernel patchset are also supported. + +Certain modes (as of this writing: SCHED_IDLEPRIO and SCHED_ISO) need a +patched kernel; see the INSTALL file for details. |
