730 The checking over compatible runtime libraries is complicated by the MPI ABI initiative
731 https://wiki.mpich.org/mpich/index.php/ABI_Compatibility_Initiative which started with
732 MPICH v3.1 (Released Feburary 2014)
733 IBM MPI v2.1 (December 2014)
734 Intel® MPI Library v5.0 (2014)
735 Cray MPT v7.0.0 (June 2014)
736 As of July 31, 2017 the ABI number still appears to be 12, that is all of the versions
737 listed above and since that time are compatible.
652
738
739 Unfortunately the MPI ABI initiative has not defined a way to determine the ABI number
740 at compile time or runtime. Thus we will need to systematically track the allowed versions
741 and how they are represented in the mpi.h and MPI_Get_library_version() output in order
742 to perform the checking.
743
744 Currently we only check for pre MPI ABI versions (and packages that do not follow the MPI ABI).
745
746 Questions:
747
748 Should the checks for ABI incompatibility be only on the major version number below?
749 Presumably the output to stderr will be removed before a release.
