This should help catch regressions that only affect a single filter. It
also allows us to set up a partitioned test that has many small blocks.
It also fixes an issue we were seeing on the dashboard where the
contour benchmark was apparently running out of resources.
Added a name option that allows the same benchmark executable to be used
in multiple benchmark tests. This allows the benchmarks to be separated.
Also added an option to pass customized arguments to the benchmark
executable to overwrite the default values.
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.
There were several tests that were disabled for hip because they either
took too long to compile or were failing. We are getting closer to
making everything work, so re-enable this part of the build.
Some of the unit tests for serial and kokkos are disable for hipcc to
properly compile.
VTKM_MATH_ASSERT and VTKM_TEST_ASSERT fail to compile with HIP in
execution environment so they are disabled with building with HIP.
Kokkos::finalize is causing error so it is temporarily disabled.
The code in `vtkm/cont/Testing.h` now requires a library, which is not
built if testing is not built. Thus, the benchmarking code was giving a
compile error if benchmarking was on but testing was off.
Change the benchmarking to not rely on anything in the Testing
framework. This means using classes in `vtkm/source` instead of
`MakeTestData`. Also avoid using the `TestValue` defined for the tests.
(In one case, we have a simple replacement.) Also had to fix a problem
with a header file not defining everything it needed to compile.
Most of this code is not templated methods. Rather, it implements over
several types to call templated functions, which creates quite a bit of
code. Rather than have all code using a reader recompile the code, just
compile it once and put it in a library.
- It also adds Google's benchmarch compare.py script
- It is installed to the build directory.
- It add a wrapper script called compare-benchmarks.py which:
- Let you run each of the benchmarks with different devices
- It adds a README.md explaining how to run the benchmarks
- BenchmarkDeviceAdapter input size range parametrized at compile time

Add the REQUIRED flag to the find_package command to find the Google
benchmark package. Without that flag, the find_package command will
happily pass if the benchmarks are not found.
However, if benchmarks is not found, then the CMake configure will then
fail because the benchmark::benchmark library is not defined. That is a
confusing error to get. Since benchmark is not a typical thing installed
on a system, this can be problematic.
Consumers of VTK-m when enabling of dropping of unused functions
will see VTK-m functions dropped. Previously this didn't happen
as VTK-m didn't build object files with the correct flags for this.
By allowing the linker to remove unused symbols we see a significant
saving the file size of VTK-m tests, examples, and benchmarks.
An OpenMP build of the tests and benchmarks goes from 168MB to
141MB which is roughly a 16% filesize reduction.
Initially I had presumed that these changes would increase link times.
But in measurements the total wall time for compilation of VTK-m has
stayed about the same ( seeing a decrease of 1.5% ). Presumably the
increased computation is offset by the reduction in file writing.
VTK-m has been updated to replace old per device benchmark executables with a device
dependent shared library so that it's able to accept a device adapter at runtime through
the "--device=" argument.
This is a library that contains parts of worklets that can be
precompiled into a library.
Currently, this library contains the implementation of ScatterCounting.
