Abstract

In parallel computations, processors generally have to exchange data. This exchange of data has a great influence on the efficiency of the parallel programs because it introduces communication delays during the execution time. The proper implementation of communication schemes on various parallel architectures is a key to good efficiency. In this paper, several communication schemes will be discussed and the numerical method of dynamic relaxation is used as an example to investigate their performance. Most commercial codes are sequential and hence it is recognised that the parallelisation of these codes must be simple and cost-effective.
