Fix using OpenMP TeamPolicy from OpenMP parallel region

9

Fixes #7357. When Kokkos OpenMP parallel constructs are called from a OpenMP parallel region, we want to serialize the kernel. This also means that we should explicitly use resources dedicated...

We found that we have https://github.com/kokkos/kokkos/blob/638664a6d0263e4246097e34011279eee079fe21/cmake/KokkosConfigCommon.cmake.in#L6 which means we define `KOKKOS_CXX_COMPILER_ID` internally but export `Kokkos_CXX_COMPILER_ID` (and we don't define the former internally at all). This makes it awkward when guarding...

#7349 restricted tests if the number of detected threads is less than the numbers of partitions requested for an OpenMP execution space instance. However, its' not clear why `exec_space_thread_safety_team_policy` and...

Similar to https://github.com/kokkos/kokkos/pull/6496, this pull request introduces a new policy property called `RegisterFileSize` that allows forcing the register file size to small or large for Intel GPUs with the SYCL...

This requires https://github.com/intel/llvm/blob/sycl/sycl/doc/extensions/experimental/sycl_ext_oneapi_enqueue_functions.asciidoc. With the new syntax, we avoid creating backend events that we aren't using anyway when we are using in-order `sycl::queue`s.

Cuda: fix long double suppression

2

We need to have the suppress before `Kokkos_Core.hpp` to be effective for the `Kokkos_NumcericTraits.hpp` and `Kokkos_Complex.hpp`. Also, enable warning and warnings as errors in the GitLab GH200 build.

Split TestHalfOperators kernels to improve compilation time with SYCL

2

This improved the compilation time of the tests from 30min to 5min. The runtime of the kernel is negligible.

This pull requedst makes the unit test results visible in the respective sections for the `jenkins` and `GItLab` CI.

#17442 made sure that we test with `Tpetra` classes with `MemorySpace::Default` but `MemorySpace::Host` is still the default. Should we change this default? From https://github.com/dealii/dealii/pull/17442#issue-2451522172: > In particular, using MemorySpace::Default allows...
