This type of error *usually* indicates a programming error, but in this
case, it's so non-specific that it's not entirely clear that this is the

The Vasp code seems to be not entirely open, so I can't try this myself.
Can you try running vasp through a debugger and putting a breakpoint in
MPI_Cart_create? The routine itself is not very long -- you should be
able to step through it and see where it is generating this error.
Having a back trace of where this error is occurring would be extremely
helpful in diagnosing the real problem.
