are already written with the assumption that an integer fits into memory
occupied by a real number, which is mostly not true for combination of default
Fortran real numbers and long integers.

ScaLAPACK Library Versioning
----------------------

From v2.2.1, the ScaLAPACK library is generated with a versioned name
(i.e. with a shared library ABI soname) according to the following pattern:

- We assume that the ABI updates with each MINOR release.
- An API update (and therefore an ABI update) will be expected with any MAJOR release.
- No ABI update should occur between PATCH releases.

Hence with the full version in triplet form as MAJOR.MINOR.PATCH,
the shared library soname will be libscalapack.so.MAJOR.MINOR.
