MUMPS (software)

MUMPS (MUltifrontal Massively Parallel sparse direct Solver) is a software application for the solution of large sparse systems of linear algebraic equations on distributed memory parallel computers. It was developed in European project PARASOL (1996-1999) by CERFACS, ENSEEIHT-IRIT and RAL. The software implements the multifrontal method, which is a version of Gaussian elimination for large sparse systems of equations, especially those arising from the finite element method. It is written in Fortran 90 with parallelism by MPI and it uses BLAS and ScaLAPACK kernels for dense matrix computations. Since 1999, MUMPS has been supported by CERFACS, ENSEEIHT-IRIT, and INRIA.

The importance of MUMPS lies in the fact that it is a rare public domain open source implementation of the multifrontal method, if not the only professional and supported one.
