CDUX Hosts 3rd Annual VTK-m Code Sprint
The CDUX group hosted a 2.5 day code sprint for the VTK-m project. The event benefited many of our students, as their research often involves using VTK-m. Many prominent members from the project attended, including Ken Moreland of Sandia, Rob Maynard of Kitware, and Dave Pugmire of Oak Ridge, among others. Remote students James Kress and Stephanie Labasan also joined us for the event, along with alum Matt Larsen.
