We should address the issue discovered by having large arrays being passed from one node to another. The issue is that numpy arrays have an attribute nbytes which is an integer describing how many bytes are in the array. When nbytes is greater than a C int (2**31 - 1), MPI errors, as it cannot convert the number.
