By using the auto keyword and decltype we can reduce the number of
complex typedefs that exist when writing device adapter algorithms.
The goal being that it is easier for developers to see the actual
algorithms being implemented, by reducing the amount of template
'noise'.
The old templated array transfer mechanism generated a lot of code
that ended up doing a simple, type-agnostic memcpy for most devices.
This patch specialized array handles for basic storage and uses a
fast-path array transfer implementation. This reduces the size of the
vtkm_cont library by 27% on gcc (from 6.2MB to 4.5MB).
Redesigns the TBB and Serial backends and the vtkm::exec::Task concept so that
we can re-use the same launching logic for all Worklets, instead of generating
per worlet code. To keep the performance the same the TilingTask now is past
a range of indices to work on, rather than a single index.
Binary size reduction:
WorkletTests_SERIAL old - 19MB
WorkletTests_SERIAL new - 18MB
WorkletTests_TBB old - 39MB
WorkletTests_TBB new - 18MB
libvtkAcceleratorsVTKm old - 48MB
libvtkAcceleratorsVTKm new - 19MB
For some reason when VTK-m was being compiled as an accelerator in VTK,
Visual Studio 2013 gave a bunch of warnings about not being able to generate
assignment operators for many classes. This happened for classes with a
const ivar that could not be automatically set. (Automatic copy constructors
are fine on this count.) I'm not sure why these warnings did not happen
when just compiling VTK-m, nor am I sure why they were generated at all as
no code actually used the copy constructors.
This commit fixes the problems by adding a private declaration for assignment
operators that cannot be automatically created. No implementation is
provided, nor should any be needed.
Change the VTKM_CONT_EXPORT to VTKM_CONT. (Likewise for EXEC and
EXEC_CONT.) Remove the inline from these macros so that they can be
applied to everything, including implementations in a library.
Because inline is not declared in these modifies, you have to add the
keyword to functions and methods where the implementation is not inlined
in the class.
