A partitioned multiprocessor (PM) has a shared global bus and nonshared local memories. This paper studies a process scheduler, called the two-tier scheduler (TTS), for a PM. In a PM local scheduling amortizes the cost of loading processes in local memory. Global scheduling migrates processes to balance load. A tunable time quantum is adjusted so the average process completes execution on the processor on which it is first scheduled, and only relatively long lived processes are rescheduled globally.
