Implementing Explicit and Implicit Coscheduling in a PVM Environment (Research Note)

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed with local workloads, balancing parallel efficiency against the local interactive response. Explicit and implicit coscheduling techniques in a PVM-Linux NOW (or cluster) has been implemented. Their performance and overheads executing local tasks and representative distributed benchmarks have been analyzed and compared.
