VTK-m has been updated to replace old per device worklet testing executables with a device
dependent shared library so that it's able to accept a device adapter
at runtime.
Meanwhile, it updates the testing infrastructure APIs. vtkm::cont::testing::Run
function would call ForceDevice when needed and if users need the device
adapter info at runtime, RunOnDevice function would pass the adapter into the functor.
Optional Parser is bumped from 1.3 to 1.7.
Rob noticed a degridation in performance in some worklet tests when
ArrayCopy was added. I hypothesize that this slowdown is doing the array
copy with TBB instead of serial in the serial tests. (There have been
some checks in the existing code to suggest that some operations in TBB
can be slower than serial.) This change forces the array copy to be on
the device for which we are testing.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
The AverageByKey.h header file had a single function that used the
device adapter algorithm ReduceByKey method to do a simple averaging of
a field. I added a second method that can do an average when given a
vtkm::worklet::Keys object. I expect this to be a common use case as we
implement transforming fields from input to output in many algorithms.
