One of the dashboards is complaining about the destructor implementation
not being used in a particular test build. I suspect it is because the
export macro has an inline, so I am trying removing it.
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.

The TryExecute function was based off of the ResolveFieldTypeAnd*
classes made for filters. To reduce the amount of code duplication,
modify these two filter classes to use the more general TryExecute
functionality.
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.
I don't know why, but under some circumstances when compiling with CUDA
and Visual Studio, the compiler was giving syntax errors when the
IteratorFromArrayPortal was using the typename keyword to reference a
type in its superclass. Get around the problem by looking directly in
the superclass.
The build automatically sets some macros when building CUDA files. Some
of the CUDA sources were setting the same macros, which was causing
warnings. Change the code to be more careful about setting preprocessor
macros.
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.
There were a few places in the source code where
std::numeric_limits::min and max were used. There is an issue with these
methods on windows because the standard libraries there define macros
with the same name. Get around this problem by either places parentheses
so that they do not look like macros or use the vtkm::Infinity methods
instead.
When compiling under VisualStudio we need to first determine if checked
iterators are enabled ( _ITERATOR_DEBUG_LEVEL ). We don't want to use the
NDEBUG key, as we could be inside a project that is in Debug mode with
disabled checked iterators.
Secondly if they are enabled we need to handle the use case of NULL iterators
that get advanced by length zero. This last case is valid, but isn't supported
by the checked iterators so we need to work around it
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).
The previous version of the bounds code required once less pass across
the data, but significantly increase the size of the resulting library:
Data for VTK-VTK-m interop:
- 7k more symbol table entries
- 1.5MB larger library
Because of the significant savings we need to use a less efficient
implementation that minimized the code size.
Certain algorithms like VertexClustering only work on certain cellset types.
It is pointless to generate the code paths for structured data cell sets,
when the algorithm can't operate on those dataset types.
Template instantiation is useful because when you are creating object files, as
uninstantiated template definitions are not are not added. Fully supporting
explicit instantiation like ITK does will require more code changes, but
this is a very minor step towards that goal.
VTK-m style guidelines dictate that all classes part of the API should
be in their own header file. Thus, we have moved the result classes out
of the filter header files and into their own headers.
We have also renamed these clases to ResultField and ResultDataSet to
better match the class naming conventions of VTK-m.
Since we are moving around these result classes, we have also revamped
their structure. They are now in a hierarchy with a common ResultBase
class. Additionally, all result classes have a reference to a complete
DataSet that can be considered the output of the filter. This will make
it easier for users to consistently deal with filter results.
These changes cover issues #60 and #62.
If Error.h was loaded before windows.h on windows compilers, then it
happily defined GetMessage and then GetMessageA and GetMessageB. However,
if the load order was reversed, then GetMessage is a macro that changes
it to GetMessageA or GetMessageB and you get an error about the same
method being declared twice.
Get around the problem by not defining GetMessage if it is already
declared as a macro.
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.
This are just some minor things I ran into while documenting these classes.
One change is just an error in a comment. The other change allows you
to specify the type in make_ArrayHandleCast as a template argument instead
of creating an instance.

because you just have to give it a filename rather than open your own file

Previously we hinted to the compiler that it should vectorized operations
where the input and output are the same array. This obviously caused problems,

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.
A previous change used the Copy method of DeviceAdapterAlgorithm to
perform the actual copy in the CopyInto method. This works fine, except
that it uses the default device adapter, and the default device adapter
may need to copy the data to the device just to copy it to another
array. Instead, use the serial device adapter, which is guaranteed to
only perform one copy of the data.
I ran into a few minor issues with the constructors to the Field class.
The big change I made was that I removed the Field constructors that
take an example type and create an empty field of that type. The problem
was that the example type was easily confused with some other type that
was supposed to describe an array. This lead to some odd behavior in the
compiler and resulted in errors in unexpected places.
The use case for this constructor is dubious. There were several tests
in the code that would create an empty field, add it to a data set, then
get it back out to pass to the worklet. The code is much simpler if you
just make an ArrayHandle of the right type and use that in the worklet
invoke directly. It is also faster to compile with smaller code because
the type is known statically (whereas it is lost the other way).
The other change was to declare references to ArrayHandle and
DynamicArrayHandle as const. There is nothing in the behavior that
invalidates the const, and it accepts arrays constructed in the
parameter.
This makes is slightly easier to use as you do not actually have to
construct the DataSetBuilder object but just call its static method.
The DataSetBuilderExplicitIterative methods are not static because they
use state of the builder object to create the data.

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.
Previously in DynamicArrayHandle the dynamic_cast was contained in a
method that was reimplemented for every different instance of
DynamicArrayHandleBase. Change that to put the dynamic_cast in a
function outside of the class so that there is only one implementation
created per ArrayHandle type.
Similarly, DynamicCellSet had its dynamic_cast in a method plus there
was a second version in the functors used for the CastAndCall method.
Consolidate all of these into a function outside of either much like
DynamicArrayHandle.
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
tests continue to work properly.
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.

Reduce the number of conditions UnitTestArrayHandleCartesianProduct
tries so that it is faster. All the conditions are pretty similar, so it
should be OK to reduce some.
Previously UnitTestDataSetBuilderRectilinear and
UnitTestDataSetBuilderRegular did an exhaustive test of all possible
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
time and at worst ctest reported the test as timed out.
It is not really necessary to perform an exhaustive test. The tests are
changed to do 10 trials using random values for dimensions and fill
methods.
