Distributed memory machines consisting of multiple autonomous processors connected by a network are becoming commonplace. Unlike specialized machines like systolic arrays, such systems of autonomous processors provide virtual parallelism through standard message passing libraries {PVM or MPI). In the area of parallelizing existing numerical algorithms, two main approaches have been proposed: automatic parallelization techniques and explicit parallelization. In the present work, we focus our studies on the second approach. The parallelization paradigm found to be most effective for numerical algorithms on distributed memory machine was to provide the user with a clientjserver architecture. The most difficult part to design is the SPMD code w...
