Comment (by rhaas):

 Also, Cactus's hdf5 files format exposes the number of processors used
 through the domain decomposition which appears in the number/name of
 datasets in files. This is true even for 1d/2d hdf5 output where only a
 single output file is created. I don't really buy into the size/speed
 argument for the current set of 1d output in tests but can certainly see
 it as desirable once we compare 3d data (which we probably should). Also
 see the discussion in #566 about related issues wrt. to being able to use
 the version control system's diff command.

 What we would also like to have is tools that can unchunk output files and
 compare data ignoring the processor decomposition (both for ASCII and HDF5
 should we use HDF5 output).

 For ASCII output, the current options to not output ghost/buffer/symmetry
 zones _almost_ do the trick. The only problem was that comment and empty
 lines are not completely ignored but their presence has to match in the
 files to be compared (or at least that used to be the case).
