The design of a new frontal code for solving sparse, unsymmetric systems
We describe the design, implementation, and performance of a frontal code for the solution
of large, sparse, unsymmetric systems of linear equations. The resulting software package,
MA42, is included in Release 11 of the Harwell Subroutine Library and is intended to
supersede the earlier MA32 package. We discuss in detail the extensive use of higher-level
BLAS kernels within MA42 and illustrate the performance on a range of practical problems
on a CRAY Y-MP, an IBM 3090, and an IBM RISC System/6000. We examine extending the …

We examine extending the frontal solution scheme to use multiple fronts to allow MA42 to be run in parallel. We indicate some directions for future development.
