Abstract
We discuss three main approaches that are used in the direct solution of sparse unsymmetric linear equations and indicate how they perform on computers with vector or parallel architecture. The principal methods which we consider are general solution schemes, frontal methods, and multifrontal techniques. In each case, we illustrate the approach by reference to a package in the Harwell Subroutine Library. We consider the implementation of the various approaches on machines with vector architecture (like the CRAY-1) and on parallel architectures, both with shared memory and with local memory and message passing.
