Comment (by rhaas):
hdf5 test suites will only help if we also either redesign the internal hdf5 format or write a clever comparison program. Right now, even 1d or 2d hdf5 files will internally show how many components (ie. processes) existed. The layout is very similar to CarpetIOASCII's output, just with hdf5 datasets instead of blocks of numbers.
You can get almost process number independent output when using compact_format, no headers, no ghost or symmetry points. The difference then is only some extra blank lines which currently are significant for the test system. One could very likely make compact format do away with the extra empty line.
