We currently build 4 versions of Open-MPI for the various Fortran
compilers: gfortran, Intel, Pathscale and PGI.

We modify the build so that the compiler name is part of the rpm
filename. For the final install of the package we end up with the


Users software environments are controlled via the Module package,
thus a user will load her favorite flavor of compiler and Open-MPI
module at login or some other time and LD_LIBRARY_PATH and PATH, etc,
are set accordingly.
