The previous implementation of `RuntimeDeviceTracker` occasionally
outputted a log at level `Info` about devices being enabled or disabled.
The problem was that the information given was inconsistent (so it would
sometimes announce one change but not announce a different corrective
change). This could cause weird confusions. For example, when you used a
`ColorTable`, it would use a `ScopedRuntimeDeviceTracker` to temporarily
force the device to `Serial`. The log will just tell you that the device
was forced to `Serial` but never tell you that the devices where
restored to include actual parallel devices.
This change helps correct these with the following changes:
* Added a new log level, `DevicesEnabled`, that is a higher level than
`Info`. All logging from `RuntimeDeviceTracker` goes to this log
level.
* Change the logging output of `RuntimeDeviceTracker` to output a list
of currently enabled devices whenever a change happens. That way you
don't have to guess what happend for each change.
* Change `ScopedRuntimeDeviceTracker` to log whenever the scope is
entered or left.
One of the dashboard compilers was complaining about not being able to
resolve which overload to use for std::size_t. (Perhaps on CUDA
std::size_t is sometimes not an unsigned 64-bit integer.) Try to correct
this by adding a templated method that casts anything to vtkm::UInt64.
The functions GetHumanReadableSize and GetSizeString accepted a
vtkm::UInt64 as the size, which should hold pretty much any reasonable
memory size and is compatible with std::size_t. But it has a different
sign-ness as vtkm::Id. So if you are holding an array size with vtkm::Id
(which is common), you could get a compiler warning when using these
functions, which is annoying. So, for convenience add a second form of
these methods that takes a vtkm::Id and automatically converts.
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.
