Hackathon
The hackathon will be held in Albuquerque starting July 30. Everyone planning on attending should register. Go to Hackathon 2019-07-30 for details.
Hank is planning to create some slides for a tutorial at the beginning of the hackathon.
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.
- Terry Turton has collected some stuff from LANL. Not sure if can be sent out.
- She might have a list of distributed data in different places
There was a long discussion on the naming conventions for topology maps. We all agreed that it should change.
Rob has been working on the split sharp edge issue that Allie reported.
Matt is struggling with static builds in VTK-m with CUDA.
Ken ran into some issues on CUDA that he thinks is related to an assumption in VTK-m that the structure of virtual objects will be the same on the host and device (even if the virtual table is different). That might not be the case with the Microsoft compiler.
- Rob does not feel that this is Ken's issue. More likely the cause is that CUDA only works with static libraries. The dynamic will not work.
No meetings next two weeks.
