schedtool can be used to query or alter a process' scheduling policy under linux
keywords = { sched_batch, batch, sched_iso, sched_rr, sched_idleprio, batch_scheduling, scheduling, policy, affinity, rt, realtime }
query and alter a process' scheduling policy
specifically: _normal | _fifo | _rr | _batch | _iso
set static priority needed for _fifo | _rr
version 1.2 was horribly broken for 2.6 - because 2.6 returns (int)4 on success, not 0, for sched_getaffinity()
version 1.2.1 should no more break on non_affinity kernels when compiled with
version 1.2.2 is only a small cleanup release
version 1.2.3 finally gets the affinity_ifdef_stuff right
version 1.2.4 features some kind of "probe" mode for priorities like sched-utils do
version 1.2.5 behaves better with newer -ck kernels and sched_iso
version 1.2.6 supports sched_idleprio directly for -ck kernels
version 1.2.7 features a man_page corrections and enhancements
version 1.2.8 features misc. code and documentation cleanups
version 1.2.9 has a fix for man-page installing and various typo fixes
version 1.2.10 fixes RPM building and the version string
version 1.3.0 uses the new cpu_set_t api found in newer glibcs
sched_batch
improve performance of long_running processes
improve performance of multiple cpu_hog processes
sched_fifo | _rr
fine_tune system for realtime_usage
cpu_affinity
avoid cache_bounces | scheduling_overhead
fully utilize dual_cpu_machines on network_load
lock processes to certains cpus at your wish
for batch_support
kernel 2.4.18+ with ingo molnar's O(1)-sched-patch
earlier 2.5.X seem to have batch_support
batch_support now is in 2.6.16+
for sched_iso
kernel 2.6.1+ with patch by con kolivas
for cpu_affinity
kernel 2.5.8+
or patched kernel (like -aa)
recent glibc
