Telecon: 2022 03 09

2022/03/09 Meeting

Agenda

Discussion Topics:

• Crusher / Spock porting

  • Update on Progress
  • Plan: Particle Advection with ARM Wind Data. (Either in situ or via replay)
  • Talk about VTK-m filters lib in VTK-h, object libs, etc.
  • Kokkos super hack is blocking features (rendering? vtk-m filter libs)
    • This is a complex order of operations related to setting up Kokkos issue
  • Rendering: Rocm goes into a opt spiral for rendering lib. (Takes a long long time)

• Ghost Data (VTK-m will provide a way to accept the name of the ghosts array)

• Cell arrays with many variables in VTK-m (Energy Groups)

  • Best path: Try lots of fields vs array var

Still Pending:

• VTK-m CUDA Arch vs Lib sizes?
  • we can explore making a path to directly pass sm_ZZ (we have a ticket for this in VTK-m)
• Cell Metrics (getting volume of each cell)
  • 2 VTK-m filters - Cell Metrics and Mesh Quality (similar, we should check Cell Metrics, we have looked at Mesh Quality)
  • We might want a fast path in VTK-m for cell metrics for structured grid
  • Cell Metrics is simpler than Mesh Quality
