Attendees: Ken Moreland (SNL), James Kress (ORNL), Berk Geveci (Kitware), Sujin Philip (Kitware), Abhishek Yenpure (UO), Mark Kim (ORNL), Brent Lessly (UO), Manish Mathai (UO), Matt Larson (LLNL), Ollie Lo (LANL)

VTK-m is now a git submodule of VTK. This will make compiling VTK with VTK-m much easier in many ways. It solves many problems with getting the "right" version of VTK-m with VTk. It also has some complications with the development process of updated VTK with new VTK-m SHAs.

Sujin has been looking at CUDA linking. Static linking works. With shared libraries, you cannot link a CUDA function from the library to elsewhere. If you are calling a virtual function, it sometimes works depending on compiler flags.

Abhishek has been running performance tests on particle advection performance. No conclusive results yet.

Brent has been working on image segmentation using VTK-m.

Manish has been working on text and line annotation. He is close to having the functionality from the OpenGL world annotator.

Matt added ability to output path lengths from the ray caster. Plan to merge to master soon.
