You might expect the f90 module to reveal the error anyway. Unfortunately which routines it covers depends on the compiler and OMPI versions in a way I don't understand -- can someone explain? For instance, it won't work with the RHEL6 system compiler (GCC 4.4), but OMPI 1.8 using GCC 4.9 will report the error with "use mpi". > I haven't used Fortran 2008 bindings in a nontrivial way yet, but it is my > understanding that Open-MPI has a good implementation of them and has for a > relatively long time. Unfortunately they won't be built if you use the system compiler on RHEL6 (which I'd guess is still be the most common HPC platform). Aren't they meant to address different problems with the subroutine signatures anyway? But strong typing is definitely good.
