Hi guys- Still no dice. The only mpi.mod files I have are the ones generated from my compile and build from source (and they are where they should be), so there's definitely no confusion amongst the modules. And specifying the fulls path to the correct mpi.mod module (like Gus suggested with the -module option) gives no change. I am running out of ideas and patience, as I'm sure you all are too! Perhaps openMPI just doesn't play nice with my compiler suite and hardware architecture...? Thanks for all the input!
