All types of cell sets should have a consistent interface. This is
tested (and fixed) for explicit and permutation cell sets. However, an
unfixed bug that has been identified is that permutation cell sets only
work for point to cell topologies. All others are not supported
correctly.
These two algorithms does not return meaningful return values. Generic interface and
implementation are both void. Remove erronous return type and statement for CUDA backend.
The parameter sweeping code is only enabled when tuning for new GPU's
so we should move it to a separate header to make DeviceAdapterAlgorithmThrust
easier to read.
The old templated array transfer mechanism generated a lot of code
that ended up doing a simple, type-agnostic memcpy for most devices.
This patch specialized array handles for basic storage and uses a
fast-path array transfer implementation. This reduces the size of the
vtkm_cont library by 27% on gcc (from 6.2MB to 4.5MB).

Previously WorkletInvokeFunctor inherited from vtkm::exec::FunctorBase,
which is also the base class for all users Worklets and for all functors
based to DeviceAdapter::Schedule.
This is done for a few reasons. The first is that we reduce the
minimum size of user worklets. Previously the users worklet would hold
a reference to the error message, and so would the wrapper class added
when calling DeviceAdapter::Schedule. Now we only have the users worklet
holding a reference.
Second, by refactoring to have two base classes we can better improve
the documentation on what responsibilities FunctorBase.h has, compared
to TaskBase.

Previously, The ArrayRangeCompute code would throw an exception if you
tried to compute the array range on an empty array. This change instead
returns empty ranges.
- Exception classes cannot be exported due to MSVC's design decisions.
See http://stackoverflow.com/questions/24511376. We must leave these
classes as header only and silence the warnings.
- TransferResource in BufferState.h must remain a header-only class since
there is no vtkm_interop library to compile the class into.
- The VTKDataSetReader hierarchy must similarly remain header-only since
there is no vtkm_io library.
- The OptionParser Action classes are part of a header-only utility and
cannot be easily compiled into a library.
-
Previously the arguments to the operator of a vtkm::cont::arg::Transport
were the control object, the input domain object, and the output range.
If you wanted to, for example, check the size of an input array to make
sure it matched the input range, you would have to know the meaning of
the input domain object to query its range. This made it hard to create
generic transports, like TransportTagArrayIn, that accept data from
multiple different input domains but need to know the input range.

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.
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.
Since we don't have explicit template instantiations for CellSetExplicit
and CellSetSingleType we need to mark them as being exported from all
libraries.

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.
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.
