MUMPS

A MUltifrontal Massively Parallel Solver

Keywords: High-Performance Computing - Direct solvers - Finite element modelling

Functional Description: MUMPS is a software library to solve large sparse linear systems (AX=B) on sequential and parallel distributed memory computers. It implements a sparse direct method called the multifrontal method. It is used worldwide in academic and industrial codes, in the context numerical modeling of physical phenomena with finite elements. Its main characteristics are its numerical stability, its large number of features, its high performance and its constant evolution through research and feedback from its community of users. Examples of application fields include structural mechanics, electromagnetism, geophysics, acoustics, computational fluid dynamics. MUMPS has been developed by INPT(ENSEEIHT)-IRIT, Inria, CERFACS, University of Bordeaux, CNRS and ENS Lyon. Since January 2019, it is developed and licensed by Mumps Technologies SAS.

News Of The Year: In June 2019, a new version of MUMPS, MUMPS 5.2.1, was released by Mumps Technologies.
