Wednesday Code Sprint Ideas

  • Continue adding content to the new VisIt Users Manual - Eric Brugger, MCM
  • Increase code coverage in our test suite. 40 of our 77 operators are currently untested. A slew of our DB readers are also untested -- Kathleen
    • [MCM] a good sub-task might be to go looking for data files we can obtain to use in testing for various DB plugins, identify plugins that are _stale_ and should probably be removed
  • VTKm operator prototyping -- Brad
  • Get up to date with VTK 7.x -- Brad
  • Is VisIt+OSPRay in a form that can be released and used -- Brad
  • Revive CDash / Automated build and testing -- Brad
  • Dry-run moving to github - MCM
  • Finish VisIt Manual RTD integration - MCM
  • AWS Windows/Ubuntu Testing - MCM
  • Move visit.llnl.gov to github hosted Jekyll/Liquid Site - MCM
  • Write a CLI script that iterates over all database objects and plots them with appropriate plots - MCM
    • A way to validate an input database
  • PICS Code - Domain decomposition, Allen, Hank, Dave Pugmire
  • Python Movie Script, Allen Cyrus
  • Update to latest MESA with OPenSWR/llvmpipe support. It seems like a doable task for a 1 day effort. it would require tweaking build_visit, adding llvm dependency, updating tarballs, and likely updating baselines. - Burlen
