VTK-m development is in a mode where backward compatibility should be
maintained between minor versions of the software. (You may get deprecation
warnings, but things should still work.) To match this behavior, the
generated CMake package now supports finding versions with the same major
release and the same or newer minor release. For example, if an external
program does this
``` cmake
find_package(VTKm 2.1 REQUIRED)
```
then CMake will link to 2.1 (of course) as well as newer minor releases
(e.g., 2.2, 2.3, etc.). It will not, however, match older versions (e.g.,
2.0, 1.9), nor will it match any version after the next major release
(e.g., 3.0).
The Doxygen html generation takes a lot more time than the xml
generation. If all you want from Doxygen is the xml for the user's
guide, that can be frustrating. Add an option to turn off the xml.
This is a start of moving the VTK-m User's Guide into the VTK-m source.
This is only the start of the process. There are several goals of this
work.
1. Integrate the documentation into the source code better to better
keep the code up to date.
2. Move the documentation over to Sphinx so that it can be posted online
and be more easily linked.
3. Incoporate Doxygen into the guide to keep the documentation
consistent.
4. Build the user guide examples as part of the VTK-m CI to catch
compatibility changes quickly.
There are numerous scripts and configuration files defined in the CI setup
and elsewhere that were missing the copyright statement. Add more types
of files to check in the CopyrightStatement test, and update the files
with the appropriate statement.
This commit adds the flag VTKm_ENABLE_GPU_MPI which when enable it
will use GPU AWARE MPI.
- This will only work with GPUs and MPI implementation that supports GPU
AWARE MPI calls.
- Enabling VTKm_ENABLE_GPU_MPI without MPI/GPU support might results in
errors when running VTK-m with DIY/MPI.
- Only the following tests can run with this feature if enabled:
- UnitTestSerializationDataSet
- UnitTestSerializationArrayHandle
The current ctest timeout in VTK-m are fine for the CI, but are too long for develoment when a test is hanging on a queued node. This commit allows a developer to turn off the majority of the hard coded timeout values which allows them to set them at the ctest command-line.
Several revisions ago, the ability to use virtual methods in the
execution environment was deprecated. Completely remove this
functionality for the VTK-m 2.0 release.
There is a Makefile include, `vtkm_config.mk`, and a package include,
`vtkm.pc`, that are configured so that external programs that do not use
CMake have a way of importing VTK-m's configuration. However, the set of
libraries was hardcoded. In particular, many of the new filter libraries
were missing.
Rather than try to maintain this list manually, use the module mechanism
in the CMake configuration to get a list of libraries built and
automatically build these lists.
This mechanism sets up CMake variables that allow a user to select which
modules/libraries to create. Dependencies will be tracked down to ensure
that all of a module's dependencies are also enabled.
The modules are also arranged into groups.
Groups allow you to set the enable flag for a group of modules at once.
Thus, if you have several modules that are likely to be used together,
you can create a group for them.
This can be handy in converting user-friendly CMake options (such as
`VTKm_ENABLE_RENDERING`) to the modules that enable that by pointing to
the appropriate group.
The reason why we did not support shared libraries when CUDA compiles
were on is that virtual methods require a special linking step to pull
together all virtual methods that might be called. I other words, you
cannot call a virtual CUDA method defined inside a library. This
requirement goes away when virtuals are removed.
Also removed the necessity of using seprable compilation with cuda.
Again, this is only needed when a CUDA function is defined in one
translation unit and used in another. Now we can enforce that all
translation units define their own CUDA functions.
Also, suppress warnings in cuda/internal/ExecutionPolicy.h
This is where we call the thrust algorithms. There must be some loop
where it, on some code path, calls back a host function. This must be in
an execution path that never happens. The thrust version has its own
suppress, but that does not seem to actually suppress the warning (it
just means that the warning does not tell you where the actual call is).
Get around the problem by suppressing the warnings in VTK-m.

Deprecate `VirtualObjectHandle` and all other classes that are used to
implement objects with virtual methods in the execution environment.
Additionally, the code is updated so that if the
`VTKm_NO_DEPRECATED_VIRTUAL` flag is set none of the code is compiled at
all. This opens us up to opportunities that do not work with virtual
methods such as backends that do not support virtual methods and dynamic
libraries for CUDA.
