Develop capabilities to support GPU execution of material volume fraction initialization on refined meshes in AMR context.

  • Initial discussion with application team(s) about capability needs
  • Refine and agree on requirements with app team
  • Develop API and vet with app team
  • Develop initial implementation for CPU execution and compare to existing app capability (accuracy, performance). Based on test problems from app team.
  • Develop GPU capability and compare solution with runs on CPU
  • Develop Axom tests as needed for capabilities

I'm just making a note here that it looks like the target host code builds Axom without MFEM, and with a serial RAJA. This impacts our ability to take MIR topological output and compute volume fractions using the intersection shaper. The intersection shaper currently uses MFEM. On a GPU-enabled platform, this may be different.
