Analysis of the solution phase of a parallel multifrontal approach
We study the forward and backward substitution phases of a sparse multifrontal factorization. These phases are often neglected in papers on sparse direct factorization but, in many applications, they can be the bottleneck so it is crucial to implement ...

Task Scheduling in an Asynchronous Distributed Memory Multifrontal Solver
SIAM Journal on Matrix Analysis and Applications (SIMAX), Volume 26, Issue 2Pages 544–565https://doi.org/10.1137/S0895479802419877We describe the improvements to the task scheduling for MUMPS, an asynchronous distributed memory direct solver for sparse linear systems. In the new approach, we determine, during the analysis of the matrix, candidate processes for the tasks that will ...

Adapting a parallel sparse direct solver to architectures with clusters of SMPs
Parallel Computing (PACO), Volume 29, Issue 11-12Pages 1645–1668https://doi.org/10.1016/j.parco.2003.05.010We consider the direct solution of general sparse linear systems baseds on a multifrontal method. The approach combines partial static scheduling of the task dependency graph during the symbolic factorization and distributed dynamic scheduling during the ...

A simple database language for personal computers
Communications of the ACM (CACM), Volume 26, Issue 9Pages 646–653https://doi.org/10.1145/358172.358181A simple database language for personal computers has been implemented by selecting a subset of the ANS MUMPS language and enhancing it so as to meet the requirements of microcomputer end-users who are unfamiliar with computers. This database language ...

The evolution of a language standard: MUMPS in the 1980s
ACM '80: Proceedings of the ACM 1980 annual conferencePages 101–104https://doi.org/10.1145/800176.809935In 1977 the MUMPS Language Standard was approved as an American National Standard (X11.1-1977) by ANSI. The specification of the MUMPS Standard was carried out by the MUMPS Development Committee, which continues to direct the evolution of the language. ...
