Mumps (for MUltifrontal Massively Parallel Solver, see http://graal.ens-lyon.fr/MUMPS ) is a software package for the solution of large sparse systems of linear equations. The development of Mumps was initiated by the European project PARASOL (Esprit 4, LTR project 20160, 1996-1999), whose results and developments were public domain. Since then, Mumps has been supported by CERFACS, CNRS, ENS Lyon, INPT(ENSEEIHT)-IRIT (main contributor), Inria, and University of Bordeaux. In the context of an ADT project (Action of Technological Development), Maurice Brémond ("SED" service) also works part-time on MUMPS.

Mumps implements a direct method, the multifrontal method; it is a parallel code capable of exploiting distributed-memory computers; its main originalities are its numerical robustness and the wide range of functionalities available.

The latest release is Mumps 4.10.0 (May 2011).
