Hi Erik,

If the bug is in bboxset2, then it might not be present in bboxset1.  Having said that, since the number of processes will affect the bboxsets that are used in domain decomposition, and hence what CarpetIOHDF5 sees, I suspect the problem is triggered by the different (larger) number of MPI processes.

Gwyneth, are you using a very large number of MPI processes for a very small domain, like for the static_tov test that you were doing before?
