Description-en: Queries/alters process' scheduling policy and CPU affinity
Schedtool can query or alter a process' scheduling policy in Linux,
specifically assigning SCHED_NORMAL, _FIFO, _RR, _BATCH, _ISO or _IDLEPRIO. 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).
