Since this is a bit complex and a recurring problem, I have expanded
the hdf5_slicer tool that comes with the Einstein Toolkit such that the
code above can be replaced by

for i in grid-coordinates.file_{0,1}.h5 ; do
  for d in x y z ; do
    hdf5_slicer --nioprocs 2 --out3d-cube --match "GRID::$d" $i $d.${i#*.}
  done
done

For this to make it into the ET someone (you can do so) needs to review
the pull request here:
https://bitbucket.org/eschnett/carpet/pull-requests/25/carpetiohdf5-add-option-nioprocs-to/diff and ideally add a "Please aply" together with a "Reviewed" state to https://trac.einsteintoolkit.org/ticket/2220#ticket

Yours,
Roland
