Asynchronous I/O

• Options
  • PETSc addition
  • In-situ plotting
    • Catalyst from Kitware library for this
• Other possibilities
  • Selective output
  • Derived output
• Other issues
  • Output formats, use HDF5/NetCDF4
    • Portability
    • A bit slower than direct MPI-IO
    • Use hashstack for install, make it default in general
    • Annotate output fields
