Abstract :
A time warping algorithm is included in the waveform relaxation circuit simulation in a distributed environment in a multicomputer network. The algorithm feature, is that it can exploit parallelism in the spatial, iteration and temporal domains. The algorithm is characterized by a relative insensitivity to the interprocessor communication overhead. The simulator is ported on a network of Sun Sparc-2 workstations using a 10 Mbits/sec. communication link. Speedups results obtained are comparable for a shared memory architecture
