There was an error in TestingPointLocatorUniformGrid in which it was
creating arrays of type vtkm::Float32 and passing them to a worklet that
expected vtkm::FloatDefault. This is corrected.
Previously when PointLocatorUniformGrid.h was compiled by the CUDA
compiler, the compiler would crash. Apparently during the ptxas
part of the compiler goes into a crazy recursion and runs out of
stack space. This appears to be a long-standing bug in CUDA
(been there for multiple releases) without a clear reason why it
sometimes rears its ugly head. (See for example
https://devtalk.nvidia.com/default/topic/1028825/cuda-programming-and-performance/-ptxas-died-with-status-0xc00000fd-stack_overflow-/)
The problem appears to be when having a doubly or triply nested
loop over a box of values to check in the uniform array. This
appears to fix the problem by converting that to a single for
loop with some index magic to convert that to 3D indices.

Previously, it was not possible to call Allocate or Shrink on an
implicit storage. The reason for this is that the implicit storage does
not represent any real memory and any attempt to modify it is wrong.
However, there are some rare cases where ArrayHandle will attempt to
"allocate" the storage even when behaving in a read-only manner. The use
case this is being created for is when an ArrayHandleImplicit first
calls ReleaseResources and then calls ReleaseResourcesExecution (or
anything else that tries to get a control-side portal). In this case,
the ReleaseResources makes the control side portal invalid and the
ReleaseResourcesExecution attempts to make it valid again by allocating
the storage to size 0. This change solves the problem by allowing the
implicit storage to be "allocated" to something smaller than originally
created.

This fix addresses issue #110. Test functions in TestingDeviceAdapter have
been updated to test large arrays through random indices using
std::uniform_int_distribution rather than testing every 100th or 50th value.

- 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.
This means that we not only setup the runtime device tracker
to force the intended device, it also means making sure
the default device is the error device.
The previous implementation of DeviceAdapterRuntimeDetector caused
multiple differing definitions of the same class to exist and
was causing the runtime device tracker to report CUDA as disabled
when it actually was enabled.
The ODR was caused by having a default implementation for
DeviceAdapterRuntimeDetector and a specific specialization for
CUDA. If a library had both CUDA and C++ sources it would pick up
both implementations and would have undefined behavior. In general
it would think the CUDA backend was disabled.
To avoid this kind of situation in the future I have reworked VTK-m
so that each device adapter must implement DeviceAdapterRuntimeDetector
for that device.
Modify PointLocatorUniform::Build to return an ExecutionObjec, Locator.
The Locator can the be passed to Worklets for finding neareast neighbor
point by calling the FindNeareastPoint method.
Somehow deducing the parameters to a static function was causing
gcc to segfault and crash. Changed around the code to use a free
function and everything works properly
Previously, when a Worklet needed a scatter, the scatter object was
stored in the Worklet object. That was problematic because that means
the Scatter, which is a control object, was shoved into the execution
environment.
To prevent that, move the Scatter into the Dispatcher object. The
worklet still declares a ScatterType alias, but no longer has a
GetScatter method. Instead, the Dispatcher now takes a Scatter object in
its constructor. If using the default scatter (ScatterIdentity), the
default constructor is used. If using another type of Scatter that
requires data to set up its state, then the caller of the worklet needs
to provide that to the dispatcher. For convenience, worklets are
encouraged to have a MakeScatter method to help construct a proper
scatter object.
`vtkm_unit_tests` now supports an MPI option that can be used to add
test that run with MPI. Adding `UnitTestFieldRangeGlobalCompute` to test
global ranges for fields.
Removing MultiBlock::GetGlobalRange API to keep things consistent with
DataSet API. Instead, one should use `FieldRangeCompute` or
`FieldRangeGlobalCompute` as appropriate.
Previously memory that was allocated outside of VTK-m was impossible to transfer to
VTK-m as we didn't know how to free it. By extending the ArrayHandle constructors
to support a Storage object that is being moved, we can clearly express that
the ArrayHandle now owns memory it didn't allocate.
Here is an example of how this is done:
```cpp
T* buffer = new T[100];
auto user_free_function = [](void* ptr) { delete[] static_cast<T*>(ptr); };
vtkm::cont::internal::Storage<T, vtkm::cont::StorageTagBasic>
storage(buffer, 100, user_free_function);
vtkm::cont::ArrayHandle<T> arrayHandle(std::move(storage));
```
This fixes the three following issues with StorageBasic.
1. Memory that was allocated by VTK-m and Stolen by the user needed the
proper free function called which is generally StorageBasicAllocator::deallocate.
But that was hard for the user to hold onto. So now we provide a function
pointer to the correct free function.
2. Memory that was allocated outside of VTK-m was impossible to transfer to
VTK-m as we didn't know how to free it. This is now resolved by allowing the
user to specify a free function to be called on release.
3. When the CUDA backend allocates memory for an ArrayHandle that has no
control representation, and the location we are running on supports concurrent
managed access we want to specify that cuda managed memory as also the host memory.
This requires that StorageBasic be able to call an arbitrary new delete function
which is chosen at runtime.
Changed the "default" ColorTable preset from "cool to warm" to
"viridis." Also made a default constructor for ColorTable that sets it
to this default preset.
The main reason to change to viridis for the default is that it is in
LAB space. We are concerned that having the default ColorTable preset
being Diverging space could lead to users using that color space
inappropriately.
