MUMPS

MUMPS
developed by P. R. Amestoy, ENSEEIHT-IRIT, J.-Y. L'Excellent, INRIA Rhône-Alpes, I. S. Duff. CERFACS/RAL, J. Koster, RAL/PARALLAB, M. Tuma, ICS Czech Rep.

MUMPS (MUltifrontal Massively Parallel Solver) is a package for solving linear systems of equations Ax=b, where the matrix A is sparse and can be either unsymmetric, symmetric positive definite, or general symmetric. MUMPS uses a multifrontal technique which is a direct method based on either the L U or the L D transpose(L) factorization of the matrix. The software requires MPI for message passing and makes use of BLAS, BLACS, and ScaLAPACK subroutines.
