Fixes#122
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.

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.
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.

ArrayHandleDiscard is intended to be used for worklets that produce
multiple output arrays when one or more outputs is not needed. It
does not allocate space for its data and the Set method is a no-op,
allowing the compiler to prune unnecessary instructions.
Reading from the array handle is not allowed.
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.
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.
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.
This will expose bugs inside the tbb backend. We had to use heap allocations
for test arrays, instead of stack as the new array increases started to
cause stack overflow on windows.
While writing a test I noticed that some of the MakeTestDataSet
hexahedrons had improper point ordering. It was close but backwards so
that all the faces pointed in instead of out.

We previously included windows.h in numerous locations using different
techniques to guard against bringing in parts of the file that are bad
(min/max macros, etc). This solves the problem by consistently using
vtkm/internal/Windows.h to setup everything.
CUDA has some strange rules about using private classes and anonymous
namespaces. For whatever reason, recent changes have introduced such an
issue. When compiling on CUDA, expose the problematic class. It is
testing code, so it does not matter much.
This is a fancy array handle that can group entries in another array by
arbitrary amounts. This allows us to implement input and output arrays
with a different sized Vec for each instance. This is necessary for
generating new topologies with cells of different types.
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.
There were many tests that created code paths for every base and Vec
type that VTK-m supports (up to 4 components). Although this is
admirable, it is also excessive, and our compile times for the tests are
very long.
To shorten compile times, remove the TryAllTypes method. Replace it with
a version of TryTypes that uses a default list of "exemplar" set of
integers, floats, and Vecs.
By far the source file that was taking the longest to compile was that
for the fancy array handles. This is because this test was being
pedantic about all the different types it was testing. This change
should drastically reduce the types actually compiled for and,
therefore, also drastically reduce the compile time for this test.
This allows callers to copy a subsection of an array into another array,
without clearing the contents of the destination array if a resize
is required.

There are various reasons why you might want to execute something but
not have a specific device to execute on. To mange this, add a general
function that will try a list of devices in order and attempt to run on
them in order.
There are several tests in the cont directory that are in header files so
that they can be recompiled for different devices. Make sure that the
tests are exclusively using the device being tested by making the error
device adapter the default.
If any part of the test tries to use the default device (which could be
different than the one being tested), a compile error will occur. Several
of these compile errors are fixed in this commit.
First, be more explicit when we mean a range of values in a field or a
spacial bounds. Use the Range and Bounds structs in Field and
CoordinateSystem to make all of this more clear (and reduce a bit of
code as well).
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.

Even when running with the serial backend, the compiler might enable SIMD
vectorization when optimizations are turned on. When this occurs, we need
to use properly atomic Add's and CAE's.
There was an inconsistency in naming classes where axes-aligned grids
with even spacing were sometimes called "uniform" and sometimes called
"regular". Maintain consistency by always calling them uniform.
Previously, DynamicArrayHandle and DynamicCellSet had slightly different
interfaces to their CastTo feature. It was a bit confusing and not all
that easy to use.
This change simplifies and unifies them by making each class have a single
CopyTo method that takes a reference to a cast object (an ArrayHandle or
CellSet, respectively) and fills that object with the data contained if
the cast is successfull. This interface gets around having to declare
strange types.
Each object also has a Cast method that has to have a template parameter
specified and returns a reference of that type (if possible).
In addition, the old behavior is preserved for DynamicArrayHandle (but
not DynamicCellSet). To avoid confusion, the name of that cast method is
CastToTypeStorage. However, the method was chaned to not take parameters
to make it consistent with the other Cast method.
Also, the IsType methods have been modified to reflect changes in
cast/copy. IsType now no longer takes arguments. However, an alternate
IsSameType does the same thing but does take an argument.
Mainly issue dealing with dimensionality of cell sets and what that represents.
Have added in code to allow user to specify a custom dimensionality so that

Synchronize the CUDA timer on both the start and end events
Previously, the timer for CUDA devices only called cudaEventSynchronize
at the end event when asking for the elapsed time. This, however, could
allow time to pass from when the timer was reset to when the start event
happened that was not recorded in the timer. This added synchronization
should make sure that all time spent in CUDA is recorded.

Previously UnitTestDataSetBuilderRectilinear and

grid sizes within a certain amount of dimensions and with some number of
ways to build point arrays. This created hundreds of thousands of cases
that were checked, and it was running a long time. At best it wasted

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.

2. Fix some untested compile errors in DataSetBuilderRectilinear
3. Added a new unit test, cont/testing/UnitTestDataSetBuilderRectilinear.cxx
4. Provided additional tests for UnitTestDataSetBuilderRegular.cxx.
The new tests in (4) were also included in (3), and provide a much more robust way of validating datasets created. It has nested for loops to do an all-all test on various ways to specify the X,Y, and Z coordinates. It computes the bounds on the coordinate system and make sure they are correct.
Note: The GetBounds() call for Rectilinear is not working, and is an item for future discussion. It is disabled for now.
Previously each device adapter only had a unique string name. This was
not the best when it came to developing data structures to track the status
of a given device at runtime.
This adds in a unique numeric identifier to each device adapter. This will
allow classes to easily create bitmasks / lookup tables for the validity of
devices.
The RuntimeDeviceInformation class allows developers to check if a given
device is supported on a machine at runtime. This allows developers to properly
check for CUDA support before running any worklets.
When writing multiple backend code users of vtkm need to use the
DeviceAdapterTraits classes, so therefore we should move them to vtkm::cont
to signify this.
Array transforms can now be created with an inverse functor, allowing for
casts back into the native array type. As a result, array transforms with
both a functor and inverse functor defined can perform read and write
operations. As an example, ArrayHandleCast now supports this operation. The
original implementation of ArrayHandleCast (i.e. read only) has been renamed
'ArrayHandleCastForInput'.
The parallel implementation in CellSetExplicit that builds cell-to-point
connectivity from point-to-cell connectivity uses a parallel sort-by-
key. The sort-by-key in the device adapter is not guaranteed to be
stable, so values associated with a particular key can be in any order.
The test for the result was expecting the connectivity array to be in a
particular order. Change the test to allow any connectivity ordering
that is still valid.
A recent change to the DeviceAdapter header includes the TBB device if
available instead of the serial device. Thus, DeviceAdapterTagSerial was
not defined automatically in all cases for the build of
UnitTestDataSetPermutation. Add the header for that explicitly.
This now allows for even more efficient construction of uniform point
coordinates when running under the 3d scheduler, since we don't need to go
from 3d index to flat index to 3d index, instead we stay in 3d index
Previously, all Fetch objects received an Invocation object in their
Load and Store methods. The point of this was that it allowed the Fetch
to get data from any of the execution objects. However, every Fetch
either just got data directly from its associated execution object or
else used a secondary execution object (the input domain) to get indices
into their own execution object.
This left two potential areas for improvement. First, pulling data out
of the Invocation object was unnecessarily complicated. It would be much
nicer to get data directly from the associated execution object. Second,
when getting index information from the input domain, it was often the
case that extra computations were necessary (particularly on structured
cell sets). There was no way to share the index information among
Fetches, and therefore the computations were replicated.
This change removes the Invocation from the Fetch Load and Store.
Instead, it passes the associated execution object and a new object type
called the ThreadIndices. The ThreadIndices are customized for the input
domain and therefore have all the information needed for a redirected
lookup. It is also a thread-local object so it can cache computed
indices and save on computation time.

Previously it was really hard to verify if a device adapter was valid. Since

These cell types are inherited from VTK, but they are basically the same
as quad and hexahedron, respectively. The only useful difference is that
pixel and voxel are supposed to be axis aligned, but you cannot
determine that by the cell shape alone (at least not just from the cell
set).
A big issue with these is that their indexing is different that of quad
and hex. The development team had a long discussion about the benefits
of the alternate indexing, but after consulting with Berk Geveci and
Will Schroder from the VTK team, that indexing is not really taken
advantage of at the cell level. Thus, it is really just a nuisance in
VTK-m.
When getting cell indices in a cell to point structured connectivity, it
was previously returning a vtkm::Vec of the maximum size and setting
invalid indices to -1. This is changed to vtkm::VecVariable, which will
reflect the actual number of indices.
I thought I made this change a while ago, but I guess I missed it.
We have been using the term "shape" in the cell set and connectivity
classes. To be consistent, use the term "shape" for the geometric
identify of the cell everywhere.
The PrintSummary for CoordinateSystem went in an infinite loop. It was
supposed to call PrintSummary of its superclass (Field), but instead it
called itself.
The PrintSummary for Field only worked for fields of type vtkm::Float32.
To make it work for all array types, I added a PrintSummary method to
DynamicArrayHandle, and Field calls that without trying to cast to a
static type.
The idea of the PointCoordinate classes was to make it easier to define
new special types of point coordinate arrays. But ultimately you have to
create an array handle type, and the CoordinateSystem class pretty much
handles everything else for you. Thus, these classes where being used
nowhere.
The point of making CoordinateSystem a special type of Field object
was so that it could handle special array types like implicit regular
point coordinates. Overload the GetData and GetBounds methods to
properly handle this type of array.
Originally, DynamicArrayHandle only automatically handled the default
type and storage lists. There was an internal subclass that expanded
that to user defined lists, but it was a bit inaccessible. This change
makes DynamicArrayHandle match the structure of DynamicCellSet. There is
now a templated base class named DynamicArrayHandleBase that can accept
any pair of lists. DynamicArrayHandle itself is really just a typedef of
DynamicArrayHandleBase with the default lists.
Previously, coordinate systems in a DataSet simply pointed to field data
specifying the coordinate information (although the ability to get that
back out of the DataSet was missing). This makes sense since point
coordinates are in fact just fields with a particular semantic meaning
to them.
However, there is an issue with this approach. It turns out that there
are special representations that are very common for point coordinates
and very uncommon for other types of fields. For example, a uniform
(a.k.a. regular or image) grid has point coordinates that are easily
derived from the point index, but such fields are quite uncommon
elsewhere.
Representing this kind of structure in the Field list of a DataSet is
problematic. Either all fields have to check to see if they are this
type, which will cause an explosion of unnecessary generated code, or
you will have to actually write out the coordinates in memory, which is
really wasteful but what was done previously.
However, by storing fields representing coordinate systems in a separate
batch, we can use these special types without the stated explosion.
Move ArrayPortalUniformPointCoordinates to the vtkm::internal namespace
since it is going to be actively used in both control and execution
environments.
Replace usage of extent with simple dimensions. We have decided that
there is not a lot of value in supporting extent in VTK-m.
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.
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.
See merge request !117
The storage used will now be aligned to `VTKM_CACHE_LINE_SIZE bytes,
resulting in slightly better cache usage and load/store performance.
This define is set in `StorageBasic.h We also now detect if Posix is
available in Configure.h and will define VTKM_POSIX with _POSIX_VERSION
if it's available.
The AlignedAllocator used by StorageBasic is also STL compatible
and can be used in STL containers so user's can use it in their
std::vector and pass aligned user memory to the storage.
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.
Also moved from vtkm namespace to vtkm::internal namespace. This change
is to then move the structured connectivity classes to the cont and exec
namespaces.
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

* Added a VTKM_IS_TOPOLOGY_ELEMENT_TAG macro to do type checks on
template arguments that are supposed to be topology element tags.
C and C++ has a funny feature where operations on small integers (char
and short) actually promote the result to a 32 bit integer. Most often
in our code the result is pushed back to the same type, and picky compilers
can then give a warning about an implicit type conversion (that we
inevitably don't care about). Here are a lot of changes to suppress
the warnings.
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.)
The DynamicCellSet will be used in place of the pointer to a CellSet
in a DataSet. This will prevent us from having to cast it all the time
and also remove reliance on boost smart_ptr.
MSVC ArrayHandle fail
Fix the fact that UnitTestArrayHandle is failing on the Windows dashboards. Also fix some of the MSVC warnings.

The test was creating a large array on the stack, and this caused a
problem on Windows for some reason. Instead of putting the array on
the stack, use an std::vector. Also reduced the size of the array
used. It seemed unnecessarily large.
Also re-enabled the tests where VTK-m allocates its own ArrayHandle
data.
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.
The CMake flag and define differ in their capitalization of the 'm' in
VTKm so I've made CMake variables that match those used in Configure.h.in,
thereby keeping the original naming of VTKm in CMake code, and VTKM in the
C++ code.
This fix also revealed some areas in CellSet and CellSetExplicit where ints
where used instead of vtkm::Ids which caused errors with child classes who
override the methods and returned a vtkm::Id instead of an int.
Also fixed issues that appeared in TestOutOfMemory which got out of date due
to not being compiled since the `VTKM_USE_64BIT_IDS` flag would never be set.
The test now runs and passes when 64bit ids are enabled.
Add data size introspection to DynamicArrayHandle.
Sometimes it is useful to know how big an array held in a
DynamicArrayHandle is. This adds two methods to DynamicArrayHandle:
GetNumberOfValues and GetNumberOfComponents. They allow you to query the
size of the array without having to statically cast to the array itself.
