Following what was done with ArrayRangeCompute, the GetRange and
GetBounds methods are embedded into the vtkm_cont library for the most
common type lists.
Also, and probably more importantly, the device adapter is no longer one
of the arguments for either of these methods. It is no longer needed as
ArrayRangeCompute no longer needs it.
Most uses of ArrayRangeCompute just want to get the range of the data
and probably don't have a particular device in mind. Thus, it is better
to use a TryExecute internally use whatever devices are available.
Note that when using TryExecute, the calling code is expected to be able
to support all devices. That might not always be the case. Thus, I am
experimenting a bit with how we incorporate this in a library. The
advantage of having the code compiled in a library is that you only have
to compile it once and the calling code does not need to worry about
CUDA, etc.
However, because ArrayRangeCompute is templated, we can only pre-compile
some subset of array handle types. The most common are compiled into the
code (matching all the predefined ArrayHandles as well as some special
cases). If the code wants to use some other type, it has to include
ArrayRangeCompute.hxx. The only place where this is necessary is a test
that intentially trys to find the range on an uncommon type.
If array portals were to support virtual methods, then we should be able
to modify this code so that we could precompile for all array handle
types.
There were some issues for device adapter algorithms (like scan and
reduce) for empty arrays or arrays of size 1. This adds tests for these
short arrays to the device adapter algorithm tests and fixes these
problems.
The basic storage has an implicit invariant that if the size of the
storage is 0 then the array is a null pointer. That invariant was broken
if the array was allocated and then Shrink or Allocate was called with
0. In that case, the array remained allocated by the size was set to 0.
This fixes the problem by making sure a Shrink(0) actually does an
Allocate(0) (to clear out the data) and that the basic storage always
frees its memory when allocating a 0 sized array.

The clip worklet will change the number of points in the result
set by adding points at the clip boundaries. The filter was updating
the clipped scalar array to reflect the new points, but not the actual
coordinate array.
This patch will cause the clip filter's result dataset to contain the
correct number of points and no longer automatically map the scalar
array onto the output, since this is easily done via the filter API.
They now grab the global runtime device tracker. In some cases, I've
added the ability to set/get the tracker to change it from the global.
In others I just removed the local copy, since it was just hooked into
the global tracker.
The RuntimeDeviceTracker.cxx contains a library method that queries the
CUDA device, which only works if compiled as a CUDA source file.
This set up will allow code that is not compiled with CUDA use a
RuntimeDeviceTracker with other code that does use CUDA.
The offsets for an ArrayHandleGroupVecVariable are always inputs
and cannot be changed, even when the array handle is used as an output.
There was a mistake where the PrepareFor* methods tried to make
the offsets mutable. In the case of an output, the offsets were not
pushed to the execution environment, and the arrays could not be looked
up.
This allows code to include the RuntimeDeviceTracker without depending
on the device-specific adapters (I think).
Also changed the implementation to use a shared_ptr for the state so you
can pass it around and share the state easier.
Before it was in the vtkm::cont::internal namespace. However, we expect
to be using this feature quite a bit more as we want VTK-m to handle
multiple devices effectively (as in, just figure it out and go).
There are two versions of ArrayRangeCompute. The first version is a
general version that computes the min and max by running a reduction on
a device. The second version was a specialization for uniform grid
coordinate arrays, which is easily computed without looking at the
values.
The problem was that the generic version of ArrayRangeCompute took two
arguments and the specialization only took one argument (because it does
not need a device). This means that templated code uses the general
version will never use the specialized version. This fix adds a device
argument to the specialized version. The extra argument is not used, but
will properly overload the general version.

It was a typedef for a Portal. Instead of setting the portal directly,
the portal is just sent to a function, so we don't directly use this
type anymore.
Not a big deal, but it could cause compiler warnings.
ConnectivityExplicitInternals::PrintSummary blindly attempted to print
all of its arrays regardless of whether they are valid. Trying to print
uninitialized arrays can be invalid in some circumstances. Instead,
check to see of the arrays are valid before printing them out. (This can
give you useful information anyway. There is a difference between an
uninitialized array and one of zero length.)
This makes it easier to see what is going on in the fancy arrays and do
diagnostics.
This change required some changes to printSummary_ArrayHandle to support
more array types.

Previously if you constructed an array handle without allocating it, you
would get an error if you tried to use the array as input. This
conflicted with some recent changes to accept empty vectors.
Now when you try to use an unallocated ArrayHandle as input (calling
PrepareForInput or PrepareForInPlace), it internally calls Allocate(0)
(to establish internal state) and sets up a valid execution ArrayPortal
of size 0.
When make_ArrayHandle gets an std::vector, it converts it to an
ArrayHandle by getting a pointer to the vector's internal array.
However, when the vector is of size 0, there is no array and it is
invalid to get a pointer. Instead, make a special case for empty
vectors.

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.
Previously, the Keys class constructor took an array of keys, made a
copy of it, and sorted the copy. This was to protect the caller in case
it needed the original keys array again. However, this copy takes a
significant chunk of time and it is probably rare in practice to ever
need the original keys array again. So instead just do an in-place sort.
The ExternalFaces filter should work fine on a CellSetSingleType.
However, the filter was not operating on them because it a templated
method that is a placeholder for "this cell set type not supported" was
matching it. This simple change allows a CellSetSingleType to match the
template for a CellSetExplicit (which is the superclass).
Previously, ExternalFaces really only supported tetrahedral meshes that
have only triangular faces. These changes support all mixes of cells and
their faces.
Unary operations on scalars and vectors will return vtkm::Float64 for
integral input types and vtkm::Float64 input types. Unary operations will
return vtkm::Float32 for vtkm::Float32 input vectors and scalars.
This allows source files to use the VTK-m version.
Note that Configure.h does not include the version. This is intentional.
First, I don't want the entirety of VTK-m to recompile every time the
version is updated (which is every time a commit happens in git).
Second, it is important that external project source files be able to
get the VTK-m version without actually loading any VTK-m code.

Changed return types for all scalar and vector unary math operations
to return vtkm::FloatDefault instead of input type. vtkm::Float64 will
be returned when the input is vtkm::Float64.
There was an error in the clip tables for clipping lines. It was
referring to edge 1 for one of the case, but of course a line has only 1
edge at index 0. Fix the error in the clipping table and also add a
check for if we get an index to an invalid line.
There was an error in the CleanGrid filter where if the
CompactPointFields flag was off it would still try to compact the point
coordinates. Add an extra check so that the coordinate systems are just
passed when this flag is off.
Modified the vector magnitude worklet to accept VecAll instead
of Vec3 and return Scalar. Modified the Magnitude() and Sqrt() functions
to return FloatDefault for all inputs except for Float64.
Perhaps we should modify other functions in Math.h and VectorAnalysis.h to
return float types for intergral arguments instead of integral types?
There was a static assert in a templated function that was never
supposed to be used. Some compilers were fine as long as there was no
use of the templated function, but others errored out anyway. Change the
implementation to use the =delete keyword instead.
This won't have as nice of an error message, but you would have to jump
through some hoops to get to this point anyway. If this still does not
work, we could just probably remove the invalid templated function. The
compiler error would get even more obfuscated, but again I don't expect
anyone to actually run into it.
The implementation was calling PrepareForOutput on the delegate arrays
rather than PrepareForInPlace, do when used with CUDA you did not get
the data on the device.
Also added a regression test to check this.
This reduces the number of weak vtables vtkm generates, resulting in
a reduction of binary sizes for projects that include vtkm classes in
multiple translation units.
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.
The CellSetExplicit and CellSetSingleType classes have an ivar that
marks the number of points. There were several instances of code
creating cell sets without specifying the number of points. This can be
very bad if subsequent code needs that information.
