[Users] PUGH issues with upgrade to Cactus 4.2.3

This is likely an issue with your MPI configuration. Either Cactus didn't recognize that you are using MPI, or you are building Cactus with one MPI implementation and are then using mpirun from another MPI implementation.

If you want help diagnosing this, then you can open a ticket on trac.einsteintoolkit.org and attach your configure options, your thorn list, as well as the screen output from configure there.

For example, when I perform an 8 processor run, I get 8 copies of full grid output instead of the 8 processors splitting up the grid and creating 1 output.  This works with both the arrangements I wrote and WaveToy.  Any ideas how to fix this?
