Hi,

smpsched is the Symmetric Multiprocessor Scheduler. It schedules your process threads for execution.

Priorities can be manipulated with the nice and renice commands and the setpri and setpriority system calls, as before. The scheduler allows a given thread to run for at most one time slice before forcing it to yield to the next dispatchable thread of the same or higher priority.

Hope this helps. Regards.
