1) On linux you must be running as root in order to be able to set SCHED_FIFO. The code is written to silently revert to non-priority scheduling if EPERM is returned.I am curious. Is it possible to specify scheduling priorities for threads, even if process global strict FIFO scheduling of isn't permissible? It is a very good idea I think to have some sort of prioritized scheduling for the threads even if it isn't perfect. I know that UNIX can prioritize time slicing of processes, but perhaps this can't yet be applied to individual threads?
pthread priority scheduling does not guarantee very much. I don't see any easy OSI way to guarantee anything about scheduling. Marty
