Rountable notes

We should try to collect some ECP data so that as we do reporting we can quickly generate relevant images. It would be great if we could also share across ALPINE and other vis projects.

There have been some code checked in that does not follow VTK-m coding styles (such as member variables not being capitalized, always using this pointer). We should be more vigilant during code reviews.

RuntimeDeviceTracker now has a single instance per thread (enforced).

Looking at CUDA 10.1. Most of our suppression for CUDA are not needed there. While removing the suppression, some warnings of real problems are being shown. Going to work through that. Also looking at some warnings with the new versions of Thrust.

Can now force cast a virtual array among types.

Sujin working on VTK/VTK-m data set. Mostly a matter of merging the code it.

There appears to be a crash in Cuda 10 linking shared libraries with the move of CellLocators into a library.

Matt has been working on spacial searches and rays.
