Rate-monotonic scheduling on uniform multiprocessors

Each processor in a uniform multiprocessor machine is characterized by a speed or computing capacity, with the interpretation that a job executing on a processor with speed s for t time units completes (s×t) units of execution. The scheduling of systems of periodic tasks on uniform multiprocessor platforms using the rate-monotonic scheduling algorithm is considered here. A simple, sufficient test is presented for determining whether a given periodic task system will be successfully scheduled by algorithm upon a particular uniform multiprocessor platform — this test generalizes earlier results concerning rate-monotonic scheduling upon identical multiprocessor platforms
