libmumps-64pord-ptscotch-5.3 5.3.5-2 (amd64 binary) in ubuntu hirsute

 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 provides shared libaries enabling reordering of data using
 PTSCOTCH. It supports 64-bit ordering (-DPORD_INTSIZE64).
