Phil, In previous versions of Open MPI, the Fortran bindings were calling the related C MPI_* subroutine, that could be wrapped in C. Now, Fortran bindings directly invoke the C PMPI_* subroutine, and hence it cannot be wrapped in C. The solution is to wrap C subroutines in C, and to wrap Fortran

Hi, What's the best way to access the PMPI profiling interface for Fortran applications built with mpifort (or one of the other Fortran compilers) from OpenMPI 2.1.1? In particular I am trying to test using Darshan via LD_PRELOAD. It works perfectly fine for C example programs (great!) but f
