Roundtable

SNL is looking VTK-m with Kokkos contention on a GPU when the simulation is also using Kokkos. First, is there any contention and if so how bad is it?

Abhi having trouble compiling VTK-m under VTK on Aurora. Problems like linking pop up. Also problems about how much memory it requires to compile a filter like Gradient.

Nicole is planning on looking at material reconstruction in VTK-m.

There is some issue with the tube filter in WarpX data.

Dave is having some issue running the Poincaré application on Frontier. The streamlines don't seem to be running correctly on the HIP hardware.
