Roundtable

Silvio was able to get the compile of VTK-m using Ascent types to work on Aurora, but only by going to a compiler released in May. Tracing this down is ongoing.

Dave is optimizing the Poincaré plot code by tuning thread parameters. So far he has got speedups of about 1.8x. This is good, but does not seem quite as good as he got on Nvidia.
