[Users] Chunked checkpoints with unchunked HDF5_3D output?

[Bernard Kelly]

Hi. Silly question time:

I'd like to write some grid functions to disk as HDF5 3D files that
are *unchunked*, but one per output time step. This I'm doing by
setting the following parameters:

IOUtil::out_mode                     = "onefile"
IOUtil::out_timesteps_per_file = 1

However, an unexpected (to me) side-effect of this is that my
checkpoint files are now also unchunked, which leads to longer
recovery (and occasionally failure).

So ... can I have chunked checkpoint files, but unchunked everything
else 3D using CarpetIOHDF5?

Thanks,

Bernard
