• 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.

Isn't this done automatically when using simfactory? I have my hdf5 data written in the separate output-00?? directories (the ones generated by symfactory at each restart) so that if one run has problems I do not lose all the data.
