Teleconference 2016-01-20

Attendees: Ken Moreland (SNL), Matt Larsen (LLNL), Eric Bruger (LLNL), Chris Sewell (LANL), Rob Maynard (Kitware), Berk Geveci (Kitware), Jeremy Meredith (ORNL), Tom Fogal (NVIDIA), Brent Lesly (OU)

Chris has a call with Kitware later for a call on distributed memory with VTK-m. Have some students this summer that will be working with VTK-m. Initially planning to look into VTK-m with Legion.

Rob working on filters branch. It is a WIP merge request. It would be good to dedicate a meeting on the filters design. Perhaps we can do that next week.

A branch checked in that made some dramatic changes to testing. It made the test sizes much smaller. That was then lost when the CellSetListTagDefault was expanded to include to rectilinear grids. We need a technical discussion after the version 1.0 release on managing executable sizes (and maybe compile time).

Jeremy has been interested in organizing an event in Europe that would be a tutorial/hackathon for VTK-m. The question is finding a venue where we would have a large enough audience to justify doing the work and travel.

Eric has been making progress on the VTK-m-VisIt integration. There are some things in the VisIt trunk. You can select using either VTK or VTK-m, and if you select VTK-m it will use it for any enabled filter.

Ken noticed that there is a WorkletMapPointToCell, but there is no WorkletMapCellToPoint. Either Ken or Jeremy will add one because not having it is just an oversight.

Matt is in the process of stripping of the rendering things off of his branch and is going to check it into a rendering module for VTK-m.

Brent has been working on a tetrahedralization worklet. He is currently in the debugging phase of that.
