Design of Parallel Numerical Methods in Message Passing and Shared Memory Environments

摘要

This paper presents a comparative view of the methodologies used in parallel methods for scientific computing. Our goal is to put in contrast the approaches taken when developing scientific software for two broad classes of parallel machines namely shared memory machines and distributed memory machines. We will illustrate our discussion with two specific algorithms namely the Alternating Directions Implicit method and the Preconditioned Conjugate Gradient method. (ERA citation 13:020231)
