Matt brought up an issue that the current vtkm::Min and Max are slow because they are calling fmin and fmax, which are not getting inlined. We should always use vtkm::Min/Max with the possible exception of compiling for a CUDA device (where these functions are special to the compiler).
Progress on the todo list for VTK-m V1.0:
- Settling of the core interface - Rob working on interface for finding what device adapters are available at runtime. Probably will move device adapter traits outside of internal.
- Standardization of "filters" - Rob is going to work on this. The current suggested approach is that filters compile to libraries and there will be a mechanism to select some alternate form of standard storage and other lists to recompile for different layouts.
- What is the distinction between multipass worklets and filters?
- Rob has a proposal for filter interfaces in issue #17
- Support worklet operations that are not one-to-one output - Done
- Basic file I/O - Done
- Basic rendering - Not started yet. It will be a bit of pressure to be ready by January
- Documentation
- Clean up doxygen - Need to get documentation syncing nightly.
- User's Guide - Trying to catch up.
- Green dashboard
- Still have problems with some CUDA dashboards
- Some working CUDA dashboards have a timer failure
- There have been some interop failures. - Rob thinks they are fixed.
- Some further output issues on Windows (see delve dashboards e.g. https://open.cdash.org/viewTest.php?onlyfailed&buildid=4123995)
- Some timeout issues on renar (e.g. https://open.cdash.org/viewTest.php?onlyfailed&buildid=4123644). Could be caused by JIT of CUDA kernels or might be because multiple things are running.
- Prototype VTK/ParaView/VisIt integration - There was some integration for the SC demo, but that might not be very close to how we integrate in general. Still need to work on that.
- (Technically not part of the release, but should indicate we have viable components.)
