The Microsoft compiler has this annoying and stupid behavior where if
you have a generic templated method/function and that method is
instantiated with a deprecated class, then the compiler will issue a
C4996 warning even if the calling code is suppressing that warning
(because, for example, you are implementing other deprecated code and
the use is correct). There is no way around this other than suppressing
the warnings for all uses of the templated method.
A recent change to the continuous integration setup has caused
`UnitTestArrayPortalValueReference` to fail on one platform.
The problem was that the test was doing two unsafe things with the
right-shift assignment operator. The first unsafe thing was using itself
as the operand.
```cpp
ref >>= ref;
```
This causes clang to give a "self assign overload" warning. Using a
variable as its own operand for a compute assign operation isn't great
style, but for some operations it can cause weird errors. The reason for
the warning is that for a true integer shift operation, the compiler
will recognize that the result should be 0. So, when using this on base
integer types, you will get 0. But overloads can give you something
different, so that might lead to unexpected results. Because we _are_
using an overload (for the `ArrayPortalValueReference` class), the
compiler tells us we can get potentially unexpected results.
OK. That seems like something we can safely ignore (and were ignoring
for some time). After all, the whole point of the
`ArrayPortalValueReference` operators is to behave exactly the same as
the values they wrap. That brings us to the second unsafe thing the test
was doing: using an invalid value as the right hand operation. And this
is where things get weird.
The test was specifically failing when being run on `Int32`. It was
setting the underlying value for `ref` to be `1000` to start with. So
the expression `ref >>= ref` was trying to right shift `ref` by 1000
bits. Logically, this should of course give you 0. However, shifting a
number by more bits than exist causes undefined behavior (c.f.
https://wiki.sei.cmu.edu/confluence/display/c/INT34-C.+Do+not+shift+an+expression+by+a+negative+number+of+bits+or+by+greater+than+or+equal+to+the+number+of+bits+that+exist+in+the+operand).
You might not get back the expected value, and this is exactly what was
happening.
What I think happened was that the compiler determined that any valid
shift would be contained in 5 bits, so it truncated the value (1000) to
the least signifcant 5 bits (which happens to be 8). It then shifted
1000 by 8 and got the value 3 instead of 0.
The fix picks an operand number that is sure to be valid.
We are moving to deprecate `ArrayHandleVirtual`, so we are removing the
feature where `VariantArrayHandle::CastAndCall` automatically casts to
an `ArrayHandleVirtual` if possible.
The big reason to make this change now (as opposed to later when
`ArrayHandleVirtual` is deprecated) is to improve compile times.
This prevents us from having to compile an extra code path using
`ArrayHandleVirtual`.
`CoordinateSystem` differed from `Field` in that its `GetData`
method returned an `ArrayHandleVirtualCoordinates` instead of
a `VariantArrayHandle`. This is probably confusing since
`CoordianteSystem` inherits `Field` and has a pretty dramatic
difference in this behavior.
In preparation to deprecate `ArrayHandleVirtualCoordinates`, this
changes `CoordiantSystem` to be much more like `Field`. (In the
future, we may change the `CoordinateSystem` to point to a `Field`
rather than be a special `Field`.)
A method named `GetDataAsMultiplexer` has been added to
`CoordinateSystem`. This method allows you to get data from
`CoordinateSystem` as a single array type without worrying
about creating functors to handle different types and without
needing virtual methods.

As a programming convenience, all `vtkm::cont::DataSet` written by
`vtkm::io::VTKDataSetWriter` were written as a structured grid. Although
technically correct, it changed the structure of the data. This meant that
if you wanted to capture data to run elsewhere, it would run as a different
data type. This was particularly frustrating if the data of that structure
was causing problems and you wanted to debug it.
Now, `VTKDataSetWriter` checks the type of the `CoordinateSystem` to
determine whether the data should be written out as `STRUCTURED_POINTS`
(i.e. a uniform grid), `RECTILINEAR_GRID`, or `STRUCTURED_GRID`
(curvilinear).
`ArrayHandle::PrepareForOutput` often has to reallocate the array to the
specified size. Previously, this allocation was not happening with the
`Token` that is passed to `PrepareForOutput`. If the `ArrayHandle` is
already attached or enqueued for that `Token`, then the allocation would
deadlock.
You can now pass a `Token` object to `Allocate`, which is what
`PrepareForOutput` does.
When you try to call the `Reduce` operation in the CUDA device adapter
with a sufficently complex interator type, you get a compile error
that says `error: cannot pass an argument with a user-provided
copy-constructor to a device-side kernel launch`.
This appears to be a bug in either nvcc or Thrust. I believe it is
related to the following reported issues:
* https://github.com/thrust/thrust/issues/928
* https://github.com/thrust/thrust/issues/1044
Work around this problem by making a special condition for calling
`Reduce` with an `ArrayHandleMultiplexer` that calls the generic
algorithm in `DeviceAdapterAlgorithmGeneral` instead of the algorithm in
Thrust.
The implementation of LagrangianFilter uses some `ArrayHandle`s
declared as `static` in the .hxx header file. One of the bad
consequences of this is that there is no control over when the
arrays are freed. We have seen where these arrays get freed
after the CUDA system is closed, which causes nasty things to
happen as the program closes.
This works around the problem until a fix is implemnted.
Often when a user gives memory to an `ArrayHandle`, she wants data to be
written into the memory given to be used elsewhere. Previously, the
`Buffer` objects would delete the given buffer as soon as a write buffer
was created elsewhere. That was a problem if a user wants VTK-m to write
results right into a given buffer.
Instead, when a user provides memory, "pin" that memory so that the
`ArrayHandle` never deletes it.
The buffer class encapsulates the movement of raw C arrays between
host and devices.
The `Buffer` class itself is not associated with any device. Instead,
`Buffer` is used in conjunction with a new templated class named
`DeviceAdapterMemoryManager` that can allocate data on a given
device and transfer data as necessary. `DeviceAdapterMemoryManager`
will eventually replace the more complicated device adapter classes
that manage data on a device.
The code in `DeviceAdapterMemoryManager` is actually enclosed in
virtual methods. This allows us to limit the number of classes that
need to be compiled for a device. Rather, the implementation of
`DeviceAdapterMemoryManager` is compiled once with whatever compiler
is necessary, and then the `RuntimeDeviceInformation` is used to
get the correct object instance.

If a test throws any unexpected exception, the test is supposed to
detect that and fail. For the STL exceptions, the test failed to return
an error code. Fix that.
For some reason, `UnitTestContourTreeUniformAugmentedFilterCUDA` was
deadlocking on some of the dashboards when `VTKM_ASSERT` was changed to
be empty when compiling CUDA kernels (for compiler performance reasons).
Fix this by calling `assert` directly in this case.
For the life of me, I cannot figure out why this would be an issue.
Clearly the `assert` is never actually called or else the test would
error out (unless a special condition in CUDA is causing it to be
hidden). But if you take out the code, something changes to lock up the
kernel.
`assert` is supported on recent CUDA cards, but compiling it appears to be
very slow. By default, the `VTKM_ASSERT` macro has been disabled whenever
compiling for a CUDA device (i.e. when `__CUDA_ARCH__` is defined).
Asserts for CUDA devices can be turned back on by turning the
`VTKm_NO_ASSERT_CUDA` CMake variable off. Turning this CMake variable off
will enable assertions in CUDA kernels unless there is another reason
turning off all asserts (such as a release build).
The VS compiler gives a warning when you override a deprecated method.
Changed the StartScene and EndScene methods in Mapper to be non-virtual
with empty implementations. Deleted the corresponding methods from all
subclasses.
Many of the operations of `VariantArrayHandleBase` are not dependent on
the TypeList parameter of the class. Still others can operate just as
well by providing a type list to a method. Thus, it is convenient to
create a superclass that is not templated. That allows us to pass around
a `VariantArrayHandle` when the type list does not matter.
This superclass is called `VariantArrayHandleCommon` because "base" was
already taken.
This makes it clear that it returns true for an invalid array handle.
The previous name implied that it was looking for an ArrayHandle in some
"valid" set, which is the opposite.

The ArrayPortalMultiplexer always called Set on the delegate portals.
However, sometimes the portals were not supported. Instead, only call
when the delegate is supported.
Probably the "right" thing to do would be to check all posible portals
for support, but that sounds like it would slow down the compile.
Previously, the VariantArrayHandle::AsMultiplexer operation silently
failed and returned an invalid ArrayHandleMultiplexer. This is now
changed to throw an exception if the desired ArrayHandleMultiplexer
cannot hold the VariantArrayHandle's array.
This merge request is Phase 1 of several to implement the distributed parallel
contour tree in VTKm. This merge requests adds the base outline for the
algorithm. The implementation of the details of the algorithm in the
BoundaryRestrictedAugmentedContourTree.h is currently still missing.
However, these will require a substantial (~3000) lines of additional code.
The goal is to stage the integration process across merge requests to make
the review process simpler.

Because ArrayHandle currently only supports one device at a time, it is
possible that a `PrepareForInput` might actually need to wait for write
access so that it could move the data between devices. However, we don't
want the `Token` to be attached for writing because that could block
other read operations.
To get around this, add a hack to WaitToWrite to allow it to attach for
reading instead of writing.
An issue that was identified for the thread safety of `ArrayHandle` is
that if several threads are waiting to use an `ArrayHandle`, there might
be an expectation of the order in which the operations happen. For
example, if one thread is modifying the contents of an `ArrayHandle` and
another is reading those results, we would need the first one to start
before the second one.
To solve this, a queue is added to `ArrayHandle` such that when waiting
to read or write an `ArrayHandle` the `Token` has to be at the top of
the queue in addition to other requirements being met.
Additionally, an `Enqueue` method is added to add a `Token` to the queue
without blocking. This allows a control thread to queue the access and
then spawn a thread where the actual work will be done. As long as
everything is enqueued on the main thread, the operations will happen in
the expected order.

Initially, the probe filter would simply not set a value if a sample was
outside the input `DataSet`. This is not great as the memory could be
left uninitalized and lead to unpredictable results. The testing
compared these invalid results to 0, which seemed to work but is
probably unstable.
This was partially fixed by a previous change that consolidated to
mapping of cell data with a general routine that permuted data. However,
the fix did not extend to point data in the input, and it was not
possible to specify a particular invalid value.
This change specifically updates the probe filter so that invalid values
are set to a user-specified value.
The `Tuple.h` file was updated with some comments that were not updated
in `Tuple.h.in`. This caused the pyexpander script to fail with
mismatched files.

Part of the commit moved fromusing a `BoundaryState` object to keeping
boundary flags in a `vtkm::Vec<bool,3>`. However, the meaning of the
flag got inverted. The `BoundaryState::IsRadiusIn?Boundary` methods
returned true if the current location was inside the bounds (i.e. _not_
on the boundary), but the new flags are true if the current location is
on the boundary (the inverse).
The updating of the code for the `StructuredPointGradient::Jacobian`
method got the flag somewhat wrong and scaled the wrong case.

We now use SumYAxis when executing with CUDA for better memory patterns.
Instead of using the heavy Pass4/Pass4WithNormals, CUDA now uses a
2 pass approach with the second pass outputting the normals and
coordinates using with significantly less warp divergence
First the Pass1 now uses WorkletVisitPointsWithCells as it is
faster since it doesn't compute some implicit boundary / neighborhood
info.
Second we reworked the logic around using `Fill` and a conditional
write of the edge case. The requirements of SMP when on a NUMA
machine is the complete opposite of what works great with CUDA.
Generally, fields that have a WHOLE_MESH association might be valid even
if the structure of the mesh changes. Thus, it makes sense for filters
to pass this data pretty much all the time.
Also cleaned up some code and comments to make the relationship between
`MapFieldOntoOutput` and `DoMapField` more clear.
When using math operators on small integers, the numbers are promoted to
32-bit ints. If that is set back to the same type, then some compilers
give a warning. This is annoying and pointless when dealing with
templated types, but we have to deal with it.
According to talks with Rob Maynard, using a worklet should be
(counterintuitively) faster than using ArrayHandlePermutation with
ArrayCopy.
This change also gives an opportunity to handle invalid indices, which
may be intentionally set when no mapping is available for that value.
For this case, MapFieldPermutation now takes an invalidValue argument to
set such values.
This function is compiled into the vtkm_filter library, so all filters
can implement this type of mapping without providing their own version

Because we only compile it once, we provide more types to convert.
Hopefully the total compile time balances out.
The only reason Keys has a template is so that it can hold a UniqueKeys
array and provide the key for each group. If that is not needed and you
want to implement a library function that takes a keys object, you can
now grab the Keys superclass KeysBase. KeysBase is not templated, so you
can pass it to a standard method in a library.

This means that the filters in the examples will no longer properly
support the policies handed to them, but that is the direction we are
headed as the policies are now deprecated.
The header was previously not marked inline and therefore
you could only have a single instance of the filter compiled
in a dynamic library / executable
Because the IO classes use ArrayHandle, they have to be compiled with
device compilers (even though they do not directly produce any device
code). This is a dumb requirement, but it is a requirement nonetheless.
Most of this code is not templated methods. Rather, it implements over
several types to call templated functions, which creates quite a bit of
code. Rather than have all code using a reader recompile the code, just
compile it once and put it in a library.
This filter is designed to work on vectors of many sizes. It was written
when selecting field types was the responsibility of the policy. It is
now the responsibility of the filter to specify possible field types.
This change is required to compile the MomentInvariants module for VTK
without policies.
The version of `Filter::Execute` that takes a policy as an argument is now
deprecated. Filters are now able to specify their own fields and types,
which is often why you want to customize the policy for an execution. The
other reason is that you are compiling VTK-m into some other source that
uses a particular types of storage. However, there is now a mechanism in
the CMake configuration to allow you to provide a header that customizes
the "default" types used in filters. This is a much more convenient way to
compile filters for specific types.
One thing that filters were not able to do was to customize what cell sets
they allowed using. This allows filters to self-select what types of cell
sets they support (beyond simply just structured or unstructured). To
support this, the lists `SupportedCellSets`, `SupportedStructuredCellSets`,
and `SupportedUnstructuredCellSets` have been added to `Filter`. When you
apply a policy to a cell set, you now have to also provide the filter.

This refactor aims to increase the performance of
AddField / Getfield at the expense of memory usage and
some bits of performances when only few fields are used
Moving to non-contiguous memory will impact cpu cache benefits,
however, since each of the Field has again another pointer to
its actual data, this benefits where actually just small.
Also the choice of map v.s. unordered_map is about the number of
elements, very likely few rehashing happenings from until <100

This fixes, which where triggered since in the new CI, one of the
docker runner set `OMP_NUM_THREADS=3`:
1. `UnitTestOpenMPDeviceAdapter`
2. `UnitTestMeshQualityFilter`
In the redution optimized implementation for _OpenMP_, it unrolls
the reduce loop in iterations of four elements. The last iteration
in the loop might overflow the loop end element (when it is not a
multiple of four).
This commit fixes this by setting the OpenMP unrolled reduce loop
end element to its previous closest multiple of four of the original end
element.

If you gave ReduceByKey a fancy output array that decorated another
array, you could get a runtime error for using an invalid array (if the
device adapter used the generic algorithm). The problem was that
ReduceByKey creates a temporary array, and that array was given the same
storage as the output array. That might not be valid for fancy arrays,
so instead use the default storage for the temporary array.
If you gave ScanInclusiveByKey a fancy output array that decorated
another array, you would get a runtime error for using an invalid array.
The problem was that ScanInclusiveByKey creates a temporary output array
and then copies the result to the actual output array. The problem was
that the temporary output array was given the same storage as the output
array, which won't work if the output array is fancy. Instead, make the
storage for the temporary array default.

One of the dashboard compilers (gcc 4.8 with cuda, I think) was giving
warnings about an unused parameter. Apparently, the compiler did not
like the parameters defined for `default` assignment operators.

c0b780543 Fix an inappropriate use of virtual methods in an execution test

The `ArrayHandleStreaming` class stems from an old research project
experimenting with bringing data from an `ArrayHandle` in parts and
overlapping device transfer and execution. It works, but only in very
limited contexts. Thus, it is not actually used today. Plus, the feature
requires global indexing to be permutated throughout the worklet
dispatching classes of VTK-m for no further reason.
Because it is not really used, there are other more promising approaches
on the horizon, and it makes further scheduling improvements difficult,
we are removing this functionality.
One of the execution tests, UnitTestScatterAndMaskWithTopology,
was defining a hierarchy of worklets that defined a virtual
operator(). It mostly still worked since the code was executed
with the final type and thus did not actually need to look up
the virtual table. However, some invalid memory access must have
been happening in CUDA since under some unpredictable circumstances
a memory protection error was happening.
This fixes the problem by removing the virtual methods.
