[ScatterView] Support for the pre/post increment operator

[anagainaru]

There is currently an inconsistency between View and ScatterView in their support of the pre/post increment operator

[masterleinad]

Do you have an example what is working for you and what is not? Are you referring to

Kokkos::View<int**> v;
Kokkos::View<int*> r
Kokkos::Experimental::ScatterView<int*> results(r);
Kokkos::parallel_for("Atomic Loop", v.extent(0),
  KOKKOS_LAMBDA(const int i) {
  auto access = results.access();
  for(int j=0; j<v.extent(1); j++)
    access(v(i,j))++;
});

not working while

Kokkos::View<int**> v;
Kokkos::View<int*,Kokkos::MemoryTraits<Kokkos::Atomic>> r
Kokkos::parallel_for("Atomic Loop", v.extent(0),
  KOKKOS_LAMBDA(const int i) {
  for(int j=0; j<v.extent(1); j++)
    r(v(i,j))++;
});

does?

@masterleinad That is correct
