You mean I should call chrt from the command line after starting the process, to modify its priority?
Normally you'd use it to run the program. But, as I said at least twice, it's Linux specific.
This documentation http://hackage.haskell.org/package/posix-realtime-0.0.0.1/src/System/Posix/R... for the posix-realtime package https://hackage.haskell.org/package/posix-realtime says that it has a sched_setscheduler function. That supposedly exists on my OS (OS X 10.9). The chrt command, on the other hand,
Does it warn you that you need privileges (probably root) to switch to a higher scheduler level? Normally realtime and other high priority schedulers require elevated privileges, whereas lower priority schedulers such as SCHED_IDLE don't. I should note that I see no manpage for sched_setscheduler on 10.9.5, nor do I find it in any of the dylibs in /usr/lib. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
