It can set static priority for _FIFO and _RR. Setting CPU-affinity and (re)nicing is also possible, making schedtool the definitive interface to Linux scheduler. . It can be used to avoid skips and glitches in A/V applications, to lock processes onto given CPUs on SMP/NUMA systems, which may be beneficial for networking or benchmarks, or to adjust nice-levels of lesser important jobs to maintain a high amount of interactive responsiveness under high load. It is also handy to manage realtime processes. . If you don't know about scheduling policies, you probably don't want to use this program - or learn and read "man sched_setscheduler". . Some supported scheduling policies (such as SCHED_ISO, or SCHED_IDLEPRIO) need a patched kernel (eg. Con Kolivas' -ck patchset).
