libmumps-scotch-dev 5.3.1-5 (riscv64 binary) in ubuntu groovy

 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 is built the MUMPS libseq dummy sequential MPI library
 with scotch support. Unless you know that you specifically need this,
 then you almost certainly want the libmumps-5.3.1 package.
