- Safety feature to avoid HDF5 files from being corrupted

  * Leo requests a feature that would allow the user to e.g., generate one

    output file per restart. With kuibit, there was interested in switching from

    the ASCII data files to the HDF5 in our research group. However, in a recent

    simulation it turned out that a node failure caused a crash as one of the

    HDF5 was being written to and we lost all data for an important

    gridfunction. If one HDF5 file was written per restart (or another safety

    feature was in place), then this would have not been an issue, as only one

    of the chunks of data would have been corrupted. Leo will open a ticket

    about this.
