Subject: [EXTERNAL] compile time dimensions of View

Dear Carter,

I have a small question that I have not been able to find a solution on the Kokkos pages or tutorials:

Is it possible to get the compile time dimensions of a Kokkos::View at compile time and if yes, how?

I would very much appreciate your help in this. Personally I think this is relevant for many application developers so it might be worth adding a word about this in the documentation.

Best regards from Munich,

Michael

Michael,

Now that you mention it we need a convenient and public mechanism.
In the mean time you can get to the underlying implementation for this information:

V::dimension::ArgN# where V is a View type and # is in [0..8)

We need to add a new public function for this.

Current ISO/C++ proposals have a member function something like:
constexpr size_type static_extent( int ) const noexcept ;
