Draft: Start making CASPT2 compatable with 64-bit MPI.
CASPT2 seems to be incompatible with 64bit MPI libraries. This MR will fix remedy that, and possibly add some updates from integer*4
to MPIInt
in other codes.
-
Documentation updated or not needed. -
Test created or not needed. -
Attribution in source files and CONTRIBUTORS.md
updated if necessary. -
Implement automatic way in cmake to detect if MPI is built for 32 or 64 bit integers. -
Test fix for more compiler/MPI library combinations.
