MPI_Init issue

When you get an error like the following this means that MPI_Init is expecting argc/argv. NULL values being passed there are not sufficient. Passing NULL to MPI_Init works on the cluster at ASC though - that is, the program that gives the following error on Olympus runs perfectly on the cluster at ASC.
