View Assignment: LayoutStride -> LayoutLeft and LayoutStride -> LayoutRight

[crtrott]

Make this assignable with runtime error checking. @AndrewGaspar

[AndrewGaspar]

It would also be nice to have built-in routines for checking if a LayoutStride is compatible with LayoutRight so you don't have to check the strides yourself.

[crtrott]

Something like this?

template<class ViewTypeA, class ViewTypeB>
bool is_assignable(const ViewTypeA& a, const VIewTypeB& b);

[crtrott]

Btw. if you feel you have time to do something about this let me know ;-).
The place for this is basically found in:
core/src/impl/Kokkos_ViewMapping.hpp

[AndrewGaspar]

Yeah, I think I more or less understand the code. I may be able to come up with a fix. The open source policy here at LANL is weird, so it may be easier if I just do it on my own time. But it would probably be useful, anyway, to just submit the approval request to contribute to Kokkos.

[crtrott]

It might be worthwhile for us to figure out what the policy is with respect to contributing to Kokkos etc. from LANL. From our side we know what all the rules are (for example around auto testing etc.) and we can basically treat you guys as if you were at Sandia. I might talk to Galen and see if we can get guidance on this.
