Abstract
High-speed networks such as the Fast Ethernet are currently available for workstation clusters. They have the potential for solving communication capacity problems for large-scale parallel finite element analysis on a workstation cluster. Parallel performance of the domain decomposition method, the domain partitioned conjugate gradient method and the parallel Gaussian elimination method is evaluated on a high-performance cluster system with Fast Ethernet and compared with different communication and computing performance. The optimization of parallel parameters for the Fast Ethernet environment is also performed based on the parallel performance evaluation. A large-scale problem with 350000 degrees of freedom has been solved in about one hour using ten workstations.
