  • Abstract
    We consider the implementation of a Pfair scheduler on a symmetric multiprocessor (SMP). Simulations presented herein suggest that bus contention resulting from simultaneous scheduling decisions can substantially degrade performance. To correct this problem, we propose a staggered model for Pfair scheduling under which scheduling points are uniformly distributed over time.
