MUltifrontal Massively Parallel sparse direct Solver

MUMPS is a Distributed Multifrontal Solver (F90, MPI based) with Dynamic Distributed Scheduling to accomodate both numerical fill-in and multi-user environment. - Solution of large linear systems with symmetric positive definite matrices; general symmetric matrices; general unsymmetric matrices. - Version for complex arithmetic. - Parallel factorization and solve phases (uniprocessor version also available). - Iterative refinement and backward error analysis. - Various matrix input formats: assembled format; distributed assembled format; elemental format. - Partial factorization and Schur complement matrix. - Several orderings interfaced : AMD, AMF, PORD Note: This is the last version released under Public Domain.
