libhypre64m-dev - 2.31.0-2 main

Hypre is a set of matrix preconditioning libraries to aid in the
solution of large systems of linear equations.
.
This package contains the headers and symlinks necessary to develop
programs which use hypre with 64-bit HYPRE_BigInt and 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
