libmumps64-dev - 5.7.3-3+b1 main

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 package supports 64-bit ordering (-DPORD_INTSIZE64).
