Fixup CUDA arch auto detection in Trilinos

Tentative fix for https://github.com/kokkos/kokkos/issues/5320#issuecomment-1209623403

SYCL should not fallback to using the host if Kokkos is configured to use a GPU arch

3

Discussion on https://github.com/kokkos/kokkos/pull/5251#discussion_r927640645 brought up that we should probably not fallback to using the host if the user explicitly specified a GPU architecture at configure time. For reference, here is...

Current status of mathematical functions

Summarize below what is currently provided by Kokkos and what is missing. x means already there X.Y denotes functions that have been added more recently in version X.Y # Basic...

Consider changing the behavior of `Kokkos::is_initialized` and providing `Kokkos::is_finalized`?

15

Currently `Kokkos::is_initialized` returns * `false` before calling `Kokkos::initialize` or after calling `Kokkos::finalize`, and * `true` in-between. This is unfortunate since it is not legal to call `Kokkos::initialize` more than once,...

Fix #3828 * Deprecate `Kokkos::log2(unsigned) -> int` * Provide alternative `Impl::bit_log2(UnsignedInteger) -> UnsignedInteger` for internal use only * Backport bit manipulation facility from C++20 https://eel.is/c++draft/bit * Remove `Impl::bit_count(unsigned int)` in...

Refactor to avoid proliferation of access traits use

This is a Work-In-Progress Opening as a base for discussion The intent of this refactor is to avoid propagating the use of access traits throughout the codebase by adapting the...

Build GPU code only for arch enabled in Kokkos with HIP

6

I realized we were compiling the code for all supported architectures because build time is ridiculous and more particularly I was getting warnings multiple times. To be honest I am...
