`ArrayExtractComponent` allows you to get a component of an array.
Unlike `ArrayHandleExtractComponent`, the type you get is always the
same: an `ArrayHandleStride`. This way, you can get an array that
contains the data of an extracted component with less templating and
potentially dramatically reduce the amount of code generated (although
some runtime integer arithmetic is added).
When `ArrayHandleCompositeVector` has only 1 component, it is supposed
to have a special template that uses the base value type rather than a
`Vec` of that type. However, the `Storage` with the value type was
missing. I'm not sure how we weren't getting compile errors before, but
moving to the new buffer arrays seems to bring about the expected error.
As we remove more and more virtual methods from VTK-m, I expect several
users will be interested in completely removing them from the build for
several reasons.
1. They may be compiling for hardware that does not support virtual
methods.
2. They may need to compile for CUDA but need shared libraries.
3. It should go a bit faster.
To enable this, a CMake option named `VTKm_NO_DEPRECATED_VIRTUAL` is
added. It defaults to `OFF`. But when it is `ON`, none of the code that
both uses virtuals and is deprecated will be built.
Currently, only `ArrayHandleVirtual` is deprecated, so the rest of the
virtual classes will still be built. As we move forward, more will be
removed until all virtual method functionality is removed.
The old version of ExecutionObject (that only takes a device) is still
supported, but you will get a deprecated warning if that is what is
defined.
Supporing this also included sending vtkm::cont::Token through the
vtkm::cont::arg::Transport mechanism, which was a change that propogated
through a lot of code.

This patch removes (or conditionally removes) the Set method from
portals that are read-only so that IsWritableArrayHandle will work as
expected. The ArrayPortal doxygen has been updated to reflect this.
The remaining exceptions are `ArrayPortalVirtual` and
`ArrayPortalMultiplexer`, since their mutability cannot be determined at
compile time.
- Use tao::tuple instead of FunctionInterface to hold array/portal
collections.
- Type signatures are simplified. Now just use:
- ArrayHandleCompositeVector<ArrayT1, ArrayT2, ...>
- make_ArrayHandleCompositeVector(array1, array2, ...)
instead of relying on helper structs to determine types.
- No longer support component selection from an input array. All
input arrays must have the same ValueType (See ArrayHandleSwizzle
and ArrayHandleExtractComponent as the replacements for these
usecases.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
The current design for ArrayPortalVirtual makes it a requirement for all
array portals (that it wraps) to have Set defined. Thus, make sure Set is
defined for all ArrayPortal. Where Set is invalid, an assert is thrown if
something calls it at runtime.
Class that need to be passed across dynamic library boundaries such as
DynamicArrayHandle need to be properly export. One of 'tricks' of this
is that templated classes such as PolymorphicArrayHandleContainer need
the Type and Storage types to have public visibility.
This makes sure that all vtkm storage tags have public visibility so
in the future we can transfer dynamic array handles across libraries.
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.
These asserts are consolidated into the unified Assert.h. Also made some
minor edits to add asserts where appropriate and a little bit of
reconfiguring as found.
Previously the make_ArrayHandleCompositeVector template was declared in
such a way that if you passed it a fancy array handle, it would change
the type to a base ArrayHandle with a fancy storage. This was
inconsistent with types generated from ArrayHandleCompositeVectorType
when using the same fancy array handle types. This change makes that
more consistent.
Previously, the ArrayHandleCompositeVector had a separate implementation
of ArrayPortal for the control and execution environments. Because I was
lazy when I implemented it, the control version did not support Get.
Since originally implementing this class, VTK-m now allows defining
methods that are declared as working in both control and execution
environments (VTKM_EXEC_CONT_EXPORT) but only work in one or the other
depending on methods of templated subclasses they call. Thus, solve this
problem by simply removing the control version of the portal and use the
same portal for both.
The ArrayHandle classes all exclusively work in the control environment.
However, CUDA likes to add __device__ to constructors, destructors, and
assignment operators it automatically adds. This in turn causes warnings
about the __device__ function using host-only classes (like
boost::shared_ptr). Solve this problem by adding explicit methods for
all of these.
Implemented this by wrapping up all these default objects in a macro.
This also solved the problem of other constructors that are necessary
for array handles such as a constructor that takes the base array
handle.
Under CUDA, the default constructors and destructors created are exported
as __host__ and __device__, which causes problems because they used a boost
pointer that only works on the host. The explicit copy constructors and
destructors do the same thing as the default ones except declared to only
work on the host.
This is to be used in place of BOOST_STATIC_ASSERT so that we can
control its implementation.
The implementation is designed to fix the issue where the latest XCode
clang compiler gives a warning about a unused typedefs when the boost
static assert is used within a function. (This warning also happens when
using the C++11 static_assert keyword.) You can suppress this warning
with _Pragma commands, but _Pragma commands inside a block is not
supported in GCC. The implementation of VTKM_STATIC_ASSERT handles all
current cases.
On one of my compile platforms, GCC was giving conversion warnings from
any boost include that was not wrapped in pragmas to disable conversion
warnings. To make things easier and more robust, I created a pair of
macros, VTKM_BOOST_PRE_INCLUDE and VTKM_BOOST_POST_INCLUDE, that should
be wrapped around any #include of a boost header file.
Previously ArrayTransfer and ArrayManagerExecution received a reference
to a Storage class in their constructor and held the reference as an
ivar. In retrospect, this is just asking for trouble. First, it is way
too easy to pass by value when you mean to pass by reference. Second, if
there ever is a bug where the Storage goes out of scope before the
classes holding a reference, it is that much harder to debug.
This includes changing methods like LoadDataForInput to PrepareForInput.
It also changed the interface a bit to save a reference to the storage
object. (Maybe it would be better to save a pointer?) These changes also
extend up to the ArrayManagerExecution class, so it can effect device
adapter implementations.
This API change effects both ArrayTransfer and ArrayManagerExecution.
This is in preparation for a future change to make the API more
consistent with ArrayHandle.
The functors in the ForEach, StaticTransform, and DynamicTransform
methods sometimes can use the index of the parameter that they are
operating on. This can be a helpful diagnostic in compile and run-time
errors. It is also helpful when linking parameters from one
FunctionInterface with those of another.
This new features are now replacing implementations using the Zip
functionality that was removed earlier. The implementation is actually
simplified a bit.
There are multiple reasons for this name change:
* The name Tuple conflicts with the boost::Tuple class, which as a
different interface and feature set. This gets confusing, especially
since VTK-m uses boost quite a bit.
* The use of this class is usually (although not always) as a
mathematical vector.
* The vtkm::Scalar and vtkm::Vector* classes are going to go away soon
to better support multiple base data type widths. Having this
abbriviated name will hopefully make the code a bit nicer when these
types have to be explicitly specified.
Also modified the implementation a bit to consolidate some of the code.
In preparation for supporting base types with more widths, add typedefs
for the base types with explicit widths (number of bits).
Also added a IdComponent type that should be used for indices for
components into tuples and vectors. There now should be no reason to use
"int" inside of VTK-m code (especially for indexing). This change cleans
up many of the int types that were used throughout.
