`vtkm::cont::testing` now initializes with logging enabled and support
for device being passed on the command line, `vtkm::testing` only
enables logging.
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.
VTK-m has been updated to replace old per device worklet testing executables with a device
dependent shared library so that it's able to accept a device adapter
at runtime.
Meanwhile, it updates the testing infrastructure APIs. vtkm::cont::testing::Run
function would call ForceDevice when needed and if users need the device
adapter info at runtime, RunOnDevice function would pass the adapter into the functor.
Optional Parser is bumped from 1.3 to 1.7.
By making RuntimeDeviceInformation class template independent, vtkm is
able to detect
device info at runtime with a runtime specified deviceId. In the past
it's impossible
because the CRTP pattern does not allow function overloading(compiler
would complain
that DeviceAdapterRuntimeDetector does not have Exists() function
defined).
The VTKM_TEST_ASSERT macro is a very useful tool for performing checks
in tests. However, it is rather annoying to have to always specify a
message for the assert. Often the failure is self evident from the
condition (which is already printed out), and specifying a message is
both repetative and annoying.
Also, it is often equally annoying to print out additional information
in the case of an assertion failure. In that case, you have to either
attach a debugger or add a printf, see the problem, and remove the
printf.
This change solves both of these problems. VTKM_TEST_ASSERT now takes a
condition and a variable number of message arguments. If no message
arguments are given, then a default message (along with the condition)
are output. If multiple message arguments are given, they are appended
together in the result. The messages do not have to be strings. Any
object that can be sent to a stream will be printed correctly. This
allows you to print out the values that caused the issue.

Vec class objects can now be constructed during compile-time
as constant expressions by calling Vec( T, ... ) constructors
or through brace-initialization.
Constant expression using fill constructor and nested vectors
of sizes greater than 4 are not supported yet.
Changes made to WrappedOperators.h for resolving overload
ambiguities in Vec construction and typecasting.
Appropriate test cases were added to UnitTestTypes.cxx.
Addresses issue #199.
This commit adds several geometric constructs to vtk-m
in the `vtkm/Geometry.h` header. They may be used from
both the execution and control environments.
We also add methods to perform projection and Gram-Schmidt
orthonormalization to `vtkm/VectorAnalysis.h`.
See `docs/changelog/geometry.md` included in this commit
for more information.
Previously, the initilaizer_list of Vec had to be the exact
same number of values as the size of the Vec. Now, we also
accept a single value that is duplicated for all values in
the Vec. That allows you to more easily construct lists
of lists with repeated values.
Add constructors to the `vtkm::Vec` classes that accept
`std::initializer_list`. The main advantage of this addition is that it
makes it much easier to initialize `Vec`s of arbitrary length.
The maybe uninitialized warnings condition logic wasn't correct the
first time, and needed to be extended for gcc4+. This locally has
resolved the problems the first try didn't solve.
These changes now allow VTK-m to compile on CUDA 7.5 by using const arrays,
when compiling with CUDA 8+ support we upgrade to static const arrays, and
lastly when CUDA is disabled we fully elevate to static constexpr.
There was a bug where if you included an empty range into another range,
the range suddenly became infinite. This is because empty ranges have
the max at -infinity and the min at infinity. If you just include the
endpoints independently (which is what include does), then the min gets
-infinity and the max gets infinity. This gets a check to make sure that
empty ranges are ignored.
When using vtkm::dot on narrow types you easily rollover the values.
Instead the result type of vtkm::dot should be wide enough to store the results
(32bits) when this occurs.
Fixes#193
The intel compiler could not generate code in a timely manner ( 12+ hours ) when
asked to produce a cross product of very long lists. By moving to a lazy
evaluation scheme we now have all compilers product a cross product in a
reasonable amount of time ( 2-4 seconds ).

If a global static array is declared with VTKM_EXEC_CONSTANT and the code
is compiled by nvcc (for multibackend code) then the array is only accesible
on the GPU. If for some reason a worklet fails on the cuda backend and it is
re-executed on any of the CPU backends, it will continue to fail.
We couldn't find a simple way to declare the array once and have it available
on both CPU and GPU. The approach we are using here is to declare the arrays
as static inside some "Get" function which is marked as VTKM_EXEC_CONT.
Rather than requiring all the arguments to be placed as member variables to
the functor you can now pass extra arguments that will be added to the functor
call signature.
So for example:
vtkm::ForEach(functor, vtkm::TypeListTagCommon(), double{42.0}, int{42});
will be converted into:
functor(vtkm::Int32, double, int)
functor(vtkm::Int64, double, int)
functor(vtkm::Float32, double, int)
functor(vtkm::Float64, double, int)
...
For std::copy to optimize a copy to memcpy, the valuetype must be both
trivially constructable and trivially copyable.
The new copy benchmarks highlighted an issue that std::copy'ing pairs
and vecs were not optimized to memcpy. For a 256 MiB buffer on my
laptop w/ GCC, the serial copy speeds were:
UInt8: 10.10 GiB/s
Vec<UInt8, 2> 3.12 GiB/s
Pair<UInt32, Float32> 6.92 GiB/s
After this patch, the optimization occurs and a bitwise copy occurs:
UInt8: 10.12 GiB/s
Vec<UInt8, 2> 9.66 GiB/s
Pair<UInt32, Float32> 9.88 GiB/s
Check were also added to the Vec and Pair unit tests to ensure that
this classes continue to be trivial.
The ArrayHandleSwizzle test was refactored a bit to eliminate a new
'possibly uninitialized memory' warning introduced with the default
Vec ctors.

All types of cell sets should have a consistent interface. This is
tested (and fixed) for explicit and permutation cell sets. However, an
unfixed bug that has been identified is that permutation cell sets only
work for point to cell topologies. All others are not supported
correctly.
