A MUltifrontal Massively Parallel Sparse direct Solver
MUMPS implements a direct solver for large sparse linear systems, with a particular focus on symmetric positive definite matrices. It can operate on distributed matrices e.g. over a cluster. It has Fortran and C interfaces, and can interface with ordering tools such as Scotch.

This addresses (jsc#SLE-14959 & jsc#SLE-17323) - updated to version 5.3.5, changes are * Fixed 2x2 pivots bug from 5.3.4 release in MPI LDLT factorization * Fixed ICNTL(8)=-2 option during analysis (code and documentation) * Fixed a rare bug (segfault) related to dynamic storage management on numerically difficult matrices * Fixed a rare deadlock in BLR for symmetric matrices * Fixed an uninitialized variable (which could lead to incorrect -19 error) * Minor fix in userguide (CNTL(1) vs. ICNTL(1) in ICNTL(36) description) * Fixed a possible runtime issue during solve, related to "TO_PROCESS" array * Assume ilp64 MPI interface only applies to Fortran in c_example.c * Note on gfortran-10 compilation added * Avoid intent on pointers (F2003-only) * More robust multithreading for matrix reformatting (arrowheads) * Fixed ICNTL(31) interpretation in case of repeated analysis * Fixed multiple mpif.h inclusion (distributed rhs, ifort+openmpi) * Fixed computation of effectively used memory statistics * Improved multithreaded performance of BLR backward solve * Fixed return code in build_mumps_int_def.c + openmp compilation (pgi) * Forbid a loop vectorization in [sdcz]sol_c.F (segfault with ifort) * New feature: distributed right-hand sides * Improved time for arrowheads construction (single MPI case, mainly) * C interface: ability to know if MUMPS_INT is 64-bit from include file * Improved BLR performance when CNTL(1)=0.0 and ICNTL(36)=1 * Fixed INFO(34),INFO(35),INFO(37),INFO(38) on processes with rank > 0 * More portable MPI_IS_IN_PLACE feature in libseq * Fixed determinant computation when Cholesky ScaLapack is used * Information on advancement (flops done) on each MPI process * Allow rhs_sparse and irhs_sparse to be unassociated if nz_rhs=0 * Fixed INFO(30) and INFO(31) computation on MPI processes with rank > 0 * OMP collapsed loops: avoid FIRSTPRIVATE on internal loop bound (for pgi) * Fix for compilers not freeing local allocatable arrays (64-bit metis)
