By making RuntimeDeviceInformation class template independent, vtkm is
able to detect
device info at runtime with a runtime specified deviceId. In the past
it's impossible
because the CRTP pattern does not allow function overloading(compiler
would complain
that DeviceAdapterRuntimeDetector does not have Exists() function
defined).
This is a subclass of ExecutionObject and a superset of its
functionality. In addition to having a PrepareForExecution method, it
also has a PrepareForControl method that gets an object appropriate for
the control environment. This is helpful for situations where you need
code to work in both environments, such as the functor in an
ArrayHandleTransform.
Also added several runtime checks for execution objects and execution
and cotnrol objects.
Adds a fancy array handle that restricts access to an array to some
window of values. It takes a start offset and a size and represents the
values between that start offset and size past that.
Also add a throwFailedRuntimeDeviceTransfer that throws a nicely
detailed message on why a something couldn't be transfered to
the requested device adapter.
-For the BoundingIntervalHierarchy CUDA had failures with using
.cxx file to implement the virtual methods
-Moving the contents to the .hxx file after discussing with Rob
over email
-Need to still work on the .cxx implementation after merge
- Reducing the stack allocation for CUDA for the BIH unit test
- Adding changes from Ken's review
- Suppress ptxas stack size warning for BoundingIntervalHierarchy
- Adding API files
- Adding back Manish's BoundingIntervalHierarchy search structure
- Updating CMakeLists.txt to accomodate these changes
- Adding the old test file from Manish - won't build for now
-Changing the existing CellLocator.h to CellLocatorHelper.h,
it's used by CellLocatorTwoLevelUniformGrid.h
-Changing unit tests and worklets that use CellLocator.h to use CellLocatorHelper.h
While making changes to how execution objects work, we had agreed to
name the base object ExecutionObjectBase instead of its original name of
ExecutionObjectFactoryBase. Somehow that change did not make it through.
In order to make the change from the current way execution obejcts are utilized to the new proposed executionObjectFactory process type checks now has to look for the new execution object factory class to check against.
Adding a new exception type `vtkm::cont::ErrorFilterExecution`. Unlike
existing exceptions, when thrown in `TryExecute`, this exception causes
the call to not attempt to execute on any other devices and let it be
thrown so that the application can catch it.
This fixes several issues with how DIY was used in MultiBlock.
Instead of using `diy::RegularSwapPartners` using
`diy::RegularMergePartners` to reduce data to block(gid=0) and then
broadcast out to all ranks (and not blocks) using
`diy::RegularBroadcastPartners`. Old code that used RegularSwapPartners
ended up building reduced result on all blocks, which was not only
unnecessary, but expensive since we would generally have more blocks
than ranks.
Remove `DecomposerMultiBlock`. This class was needed due to my
misunderstanding of how the decomposer works.
`diy::RegularDecomposer<diy::DiscreteBounds>` provides all the necessary
functionality provided by `DecomposerMultiBlock`.
The new and improved vtkm::cont::ColorTable provides a more feature complete
color table implementation that is modeled after
vtkDiscretizableColorTransferFunction. This class therefore supports different
color spaces ( rgb, lab, hsv, diverging ) and supports execution across all
device adapters.
DIY now depends on MPI optionally. Hence we no longer need to depend on
DIY optionally based on whether MPI was enabled. Update cmake and c++
code to always use DIY-based components.
DIY is built with MPI support if VTKm_ENABLE_MPI is ON.
By hard coding the PrepareForDevice to know about all the different VTK-m
devices, we can have a single base class do the execution allocation, and not
have that logic repeated in each child class.
