Abstract |
The numerical core of iterative algorithms is a matrix-vector multiplication (MVM) involving the large sparse matrix. In this work some issues related to effective parallel implementation of sparse MVM on PC clusters are discussed. Attention is focused on the interprocessor communications and compression step involved in TJDS-MVM. We present three different communication approaches for parallel implementation and evaluate the contributions on PC cluster. |
