Abstract

Each processor in a uniform multiprocessor ma-chine is characterized by a speed or computing capac-ity, with the interpretation that a job executing on aprocessor with speed s for t time units completes (s \times t)units of execution. The scheduling of systems of periodic tasks on uniform multiprocessor platforms usingthe rate-monotonic scheduling algorithm is considered here. A simple, sufficient test is presented fordetermining whether a given periodic task system willbe successfully scheduled by algorithm upon a particularuniform multiprocessor platform - this test generalizes earlier results concerning rate-monotonic scheduling upon identical multiprocessor platforms.
