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.
The `VTKM_LOG_SCOPE` macro was not working as intended. It was supposed
to print a log message immediately and then print a second log message
when leaving the scope along with the number of seconds that elapsed
between the two messages.
This was not what was happening. The second log message was being
printed immediately after the first. This is because the scope was taken
inside of the `LogScope` method. The macro has been rewritten to put the
tracking in the right scope.
VTK-m contains a helpful method named `vtkm::cont::TypeToString` that
either takes a type as a template argument or a `std::type_info` object
and returns a human-readable string for that type.
The standard C++ library has an alternate for `std::type_info` named
`std::type_index`, which has the added ability to be used in a container
like `set` or `map`. The `TypeToString` overloads have been extended to
also accept a `std::type_info` and report the name of the type stored in
it (rather than the name of `type_info` itself).
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.
