Abstract

To leverage the computational capability of modern supercomputers, existing algorithms need to be reformulated in a manner that allows for many concurrent operations. In this paper, we outline a framework that reformulates classical Schwarz waveform relaxation so that successive waveform iterates can be computed in a parallel pipeline fashion after an initial start-up cost. The communication costs for various implementations are discussed, and numerical scaling results are presented.
