libmumps64-ptscotch-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 with ptscotch support.
 .
 This package supports 64-bit ordering (-DPORD_INTSIZE64).
