The constructor for execution whole array was wrong and would result in compilation error if used. This fixes that and adds a test path for testing ExecutionWholeArray with ExecutionWholeArrayConst.
This class was used to store a group of from field data in a topology
map. However, the fetching has been changed to use a customized class
for each type of fetch that can be optimized for the fetch type and does
not require to know the number of items in the fetch at compile time.
Thus, this class is no longer needed, so it is being removed.
This change removes the requirement to specify some maximum cell length
in each of the worklets, which is basically impossible. It also makes
some of the loading more lazy, which might help reduce the number of
registers required in a worklet.
We want to be able to get topological connections where it is difficult
to know how many values you get each time. In this change, the type of
the vector holding the from indices is determined from the connectivity
object, and the worklet does not know the type (it must be templated).
Although you do not need to specify the max number for this value set
(you still currently do for field values), we still need to change the
type for explicit sets that uses something that does not rely on the Vec
class. The cell-to-point method also needs a Vec wrapper that allows it
to shorten the vector dynamically.
Previously, all arrays passed to worklets were designated as either
input or output. No in-place operation was permitted. This change adds
the FieldInOut tag for ControlSignature in both WorkletMapField and
WorkletMapTopology that allows you to read and write from the same
array.
Clean up CellSet
Underneath the CellSet implementation is a set of supporting classes that manage the actual structure in both the control and execution environments. However, the implementation of these classes was a bit confusing and inconsistent. The following changes are made:
* Most significantly, there is no longer any Connectivity classes in the control environment. This functionality has been wrapped up into the CellSet classes, which is more consistent and easier to understand. (There was a definite distinction between CellSet and Connectivity, but it was subtle and difficult to understand.) This also means that edits to CellSets happen to CellSets directly.
* The set of classes for structured and explicit cell sets match. There is different functionality within, but the class naming and meaning are consistent.
* Make the class names more consistent with the rest of VTK-m class names. Specifically classes like ExplicitConnectivity become ConnectivityExplicit. Also, the words regular and structured were being used interchangeably. Now, always use structured except when dealing specifically with grids of regular spacing.
* The connectivity classes were using the nomenclature "From" and "To" to specify topological elements of links. The same concept in worklet classes were using the nomenclature "Src" and "Dest." For consistency, all references are changed to "From" and "To".
* Unlike explicit cell sets, structured cell sets have functionality shared between control and execution environments. Rather than duplicate it or create unique exposed classes, have a shared internal implementation in vtkm::internal.

(Re-) Add a helper structure that holds the connectivity information for
a particular topology connection (e.g. from points to cells) to make it
easier to manage connections in multiple different directions in
CellSetExplicit.
Unlike the previous version of connectivity, this structure is
considered "internal" and not exposed through the API so that
CellSetExplicit can better manage the data. Also, many of the helper
methods remain in CellSetExplicit since they were specific for point-to-
Also, CellSetExplicit has a mechanism to take an arbitrary pair of
TopologyElementTags and get the appropriate connectivity. This should
simplify adding connections in the future.
In the CellSet and related classes, a connection was referred to by a
"from" topology element and a "to" topology element. However, in the
worklet control signature tags the elements were referred to by "src"
and "dest." To make things consistent, use "from" and "to" everywhere.
Most of VTK-m follows the convention of calling the 0D topology elements
"points" (which follows the convention of VTK). However, there were
several places where they were referred to as "nodes." Make things
consistent by calling them points everywhere.
Also merged some redundant ExecutionSignature tags.
Previously there was a Connectivity* structure for both the control
environment and the execution environment. This was necessary before
because the connectivity is explicit to the from and to topology
elements, so you would get this structure from the appropriate call to
CellSet*. However, the symantics are changed so that the type of
connectivity is selected in the worklet's dispatcher. Thus, it is now
much cleaner to manage the CellSet structure in the CellSet class itself
and just have a single set of Connectivity* classes in the execution
environment.
Previously, the items used to identify parts of topology like points,
cells, faces, etc. were in an enumeration. However, they are only really
used in template specialization, and it is easier to use tags in this
case. So, change the enumeration to a set of tag structures. Also made
the following changes:
* Renamed TopologyType to TopologyElement, which is more indicative of
what we are referring to.
* Moved the structures from the vtkm::cont namespace to the vtkm
namespace. There is no reason not to be able to use them from either the
control or execution environments.
* Added a VTKM_IS_TOPOLOGY_ELEMENT_TAG macro to do type checks on
template arguments that are supposed to be topology element tags.
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.
The Invoke of the topology dispatcher is also changed to expect a
concrete cell set (which the DynamicCellSet is automatically cast to)
rather than a connectivity structure. The dispatcher calls the
GetNodeToCellConnectivity method for you. (That is currently the only
one supported.)
MSVC ArrayHandle fail
Fix the fact that UnitTestArrayHandle is failing on the Windows dashboards. Also fix some of the MSVC warnings.
See merge request !101
The most common changes were making class members uppercase and spelled
out, adding "this->" whenever a class member is used, and declare
functions and members with export macros. Also fixed some uses of int
(instead of vtkm::Id or something similar) and a bit of indentation. I
also sprinkled some const goodness over the code.
It should be noted that I had about a week delay between first making
these changes and checking them in. In the mean time Sujin also made
some similar changes, so there might be some repetative changes.
Remove the usage of enable_if as return type to reduce binary size.
Using enable_if/disable_if as a return type has a negative impact on
binary size compared to use a boost::true/false_type as a method parameter.
For comparison the WorkletTests_TBB sees a 6-7% reduction in binary size when
compiled with O3.

Some fixes to VertexClustering
VertexClustering previously only worked with data of a specific floating
point type (32 bit for point coordinates). Add some templates to accept
either 32 bit or 64 bit floating points for point coordintes and be a
bit more careful about implicit type conversions.
I also made some changes to conform better with the VTK-m coding
standards. The most common changes are using 2 space indentation for all
block levels, capitolizing and using camel case for all class members,
and prefixing "this->" to all use of internal class members.
See merge request !64
When mixing precision, it is possible for the computation to pick a grid
size greater than the requested number of dimensions. This change
ensures that you never get more dimensions than requested. (Thanks to
Chun-Ming Chen for the fix.)
The test now behaves the same way as it did before the last change.

Implement a way to pass a portal to worklet as a parameter.
This is built ontop of the ExecutionObjectBase work, and is designed to show
other developers how they can create custom objects that are shared among
all worklets, but are passed as parameters to the worklet.

CellSetExplicit can now use different storage backends to allow
for cheaper representations of the data. For example a pool of triangles
can now implicit handles for shape and num indices.
This does raise the question if runtime polymorphism is the best approach
for CellSet, or if we should do some from of CRTP.
The ExecObject tag for the ControlSignature was not declared right so
would cause a compile error if it was ever used. Clearly this was not
being tested properly, so the dispatcher base unit test now passes an
ExecObject parameter.
Previously, DispatcherBase had an ivar to determine whether to use the
numInstances passed on the stack or to use a 3D range held in a
different ivar. This change allows either a 1D range or 3D range to be
passed on the stack, which I expect to be closer to how we we handle
this when 3D ranges are fully supported.
This also fixes a bug introduced with commit
fdac208acbfa47b613d899a36cefc32a01e8f0a8 where the Use3DSchedule ivar
was not set correctly in UnitTestDispatcherBase.
NVCC is unable to handle finding the worklets when they are in an anonymous
namespace. It only looks at the the anonymous namespaces included by the
files that device code uses, and misses our anon namespace. Moving to a named
namespace solves these issues.
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.
A couple of tests were failing with the Intel compiler due to
imprecision in comparing floating point values.
Also snuck in some minor documentation fixes in a comment for
FunctionInterface.
It's easy to put accidently put something that is not a valid tag in a
ControlSignature or ExecutionSignature. Previously, when you did that
you got a weird error at the end of a very long template instantiation
chain that made it difficult to find the offending worklet.
This adds some type checks when the dispatcher is instantated to check
the signatures. It doesn't point directly to the signature or its
parameter, but it is much closer.
Instead of just checking that a dispatcher's Invoke input is an
ArrayHandle, also check that the ValueType of the ArrayHandle is
compatible with the types of the worklet operator. This is done by
adding a template argument to the ControlSignature tags that is a type
list tag that gets passed to the type check.
This is a simple version of a dispatcher, but an important one.
Note that there is an issue brought up with UnitTestWorkletMapField in
that there needs to be better ways to specify worklet argument types.
These changes support the implementation of DispatcherBase. This class
provides the basic functionality for calling an Invoke method in the
control environment, transferring data to the execution environment,
scheduling threads in the execution environment, pulling data for each
calling of the worklet method, and actually calling the worklet.
