The effects of communication latency upon synchronization anddynamic load balance on a hypercube

摘要

The effects of communication latency upon dynamic load balance forcomputations which require global synchronization are discussed.Experimental results from the study of the performance of iterationmethods on an NCUBE 1 are presented. Discussions are restricted to thecase when all processing elements (PEs) execute the sameprogram, but on different data; the so-called SPMD paradigm
