Abstract
An efficient parallel implementation of the Adaptive Dynamic Relaxatio n (ADR) algorithm is developed. It is designed to minimize the extent and frequency of interprocessor communication. This version is impleme nted on a 128-processor Intel hypercube and on a cluster of 16 enginee ring workstations using PVM. Relative speedups are presented for the n on-linear static analysis of two- and three-dimensional hyperelastic s ystems involving frictionless contact. Impressive speedups are achieve d on the hypercube and demonstrate the high scalability of the ADR alg orithm. Good speedups are also achieved using PVM, suggesting that PVM is a viable parallel-processing resource for this application.
