Hello All,
Version 2.0 of Concurrent's multiprocessor control library (mpadvise)
and user-level tool (run) are now available. A source tarball, README
and ChangeLog can be found here:
http://www.ccur.com/realtime/oss
These are GPL'd clean-room implementations of similar tools that
have been available in our proprietary *nix for quite some time,
and so the interfaces have a fair amount of mileage under their
belts. Note that the scope is somewhat wider than just MP.
Briefly, it works like this:
# run -b 0 foobar
(runs foobar biased to cpu 0)
# run --negate --bias 0 foobar
(runs foobar anywhere but cpu 0)
but it can combine MP and scheduler parameters easily too:
# run --bias 0-2,5 --policy rr --priority 50 autopilot
Here's the full help output. See the man pages in the tarball
for details on using the mpadvise(3) library service.
# run --help
Usage: run [OPTIONS] { COMMAND [ARGS] | PROCESS_SPECIFIER }
Set scheduling parameters and CPU bias for a new process or a list
of existing processes.
OPTIONS can be one or more of the following options:
-b, --bias=LIST Set the CPU bias to the LIST of CPUs;
CPUs are numbered starting from 0
-s, --policy=POLICY Set the scheduling policy to POLICY
(SCHED_OTHER, SCHED_RR or SCHED_FIFO)
-P, --priority=LEVEL Set the scheduling priority to LEVEL;
SCHED_FIFO and SCHED_RR range: 1 to 99
SCHED_OTHER: only priority 0 is valid
-q, --quantum=QUANTUM Set the SCHED_RR quantum to QUANTUM;
use --quantum=list for valid settings
-N, --negate Negate the CPU bias list; all CPUs
except those listed will be selected
-f, --fork Fork COMMAND and return immediately
-c, --copies=COUNT Run COUNT identical copies of COMMAND
-i, --info Output process environment information
-V, --version Output version information and exit
-v, --verbose Output information before each action
-h, --help Display this help and exit
PROCESS_SPECIFIER is exactly one of the following options:
-p, --pid=LIST Specify LIST of existing PIDs to modify
-g, --group=LIST Specify LIST of process groups to modify; all
existing processes in the groups will be modified
-u, --user=LIST Specify LIST of users to modify; all existing
processes owned by the users will be modified
-n, --name=LIST Specify LIST of existing process names to modify
Multiple comma separated values can be specified for all LISTs and ranges
are allowed where appropriate (e.g. "run -b 0,2-5 autopilot").
See the run(1) man page for more information.
Take care,
Jason
