With the major revision 2.0 of VTK-m, many items previously marked as
deprecated were removed. If updating to a new version of VTK-m, it is
recommended to first update to VTK-m 1.9, which will include the deprecated
features but provide warnings (with the right compiler) that will point to
the replacement code. Once the deprecations have been fixed, updating to
2.0 should be smoother.
When you used the `AddHelp` option to `Initialize`, it added a
`--vtkm-help` option and `-h`, but not `--help`, which was weird. It
also avoided adding `--vtkm-help` when `AddHelp` was not used, but did
print out a usage statement under other circumstances.
This changes the behavior to add `--vtkm-help`, `--help`, and `-h` when
`AddHelp` is on and only `--vtkm-help` when it is off.
This has the side effect of initialing MPI_Init (and will also
call MPI_Finalize at program exit). However, if the calling
code has already called MPI_Init, then nothing will happen.
Thus, if the calling code wants to manage MPI_Init/Finalize,
it can do so as long as it does before it initializes VTK-m.
When a library requires reading some command line arguments through a
function like Initialize, it is typical that it will parse through
arguments it supports and then remove those arguments from argc and argv
so that the remaining arguments can be parsed by the calling program.
VTK-m's initialize did not do that, so add that functionality.
The RuntimeDeviceTracker had grown organically to handle multiple
different roles inside VTK-m. Now that we have device tags
that can be passed around at runtime, large portions of
the RuntimeDeviceTracker API aren't needed.
Additionally the RuntimeDeviceTracker had a dependency on knowing
the names of each device, and this wasn't possible
as that information was part of its self. Now we have moved that
information into RuntimeDeviceInformation and have broken
the recursion.
Also
- Renamed vtkm::cont::make_DeviceAdapterIdFromName to just overload
make_DeviceAdapterId.
- Refactored CMake logic for unit tests
- Since we're now querying the device tracker for the names, they
cannot be all caps.
- Updated usages of InitLogging to use Initialize instead.
- Added changelog.
