libhypre64m-2.26.0 2.26.0-3 (riscv64 binary) in ubuntu lunar

 Hypre is a set of matrix preconditioning libraries to aid in the
 solution of large systems of linear equations.
 .
 This package contains the shared library supporting 64-bit
 HYPRE_BigInt with 32-bit HYPRE_Int (--with-mixedint).
 .
 Note that segfaults have been reported in MPI tests. libhypre64m
 (mixedint) might not be safe, and should be considered experimental.
 Use with care (or do not use). See
