Is there a way to prefer one MPI implementation over another? Also to enforce that they are built with Fortran support? The best support & performance for OpenCoarrays is obtained with MPICH rather than OpenMPI\r\n 1. What's the correct/best way to specify that this project requires GCC >= 5.1? (certainly GFortran must be >= 5.1 I'm not sure if you can mix GCC versions across C and Fortran compilers)\r\n 1.

(i.e. GCC >= 5.3) I know this hasn't been released yet, but it resolves at least one of these issues."}}
