Hi Geraint,

In apollo.run, you call "mpirun".  This might not be the right mpirun. It might be better to call it using $MPIDIR/bin/mpirun, if that is where it is located.  

From the output file, you can see that there are multiple Cactus banners appearing.  This indicates that each mpi process is starting thinking it is the only one there. This is a smoking gun for a mismatch between the MPI versions used to compile and run, so I would focus on that possibility.
