Multiple packages: Erroneous use of Kokkos_ENABLE_OpenMP, Kokkos_ENABLE_Pthread, Kokkos_ENABLE_Serial, Kokkos_ENABLE_Cuda*

[ndellingwood]

Bug Report

This issue is to report and coordinate updates to Trilinos packages of erroneous use of CMake options Kokkos_ENABLE_OpenMP, Kokkos_ENABLE_Pthread, Kokkos_ENABLE_Serial, Kokkos_ENABLE_Cuda*

The usages above were deprecated pre-3.0 release and should be updated as:
Kokkos_ENABLE_Serial -> Kokkos_ENABLE_SERIAL
Kokkos_ENABLE_OpenMP -> Kokkos_ENABLE_OPENMP
Kokkos_ENABLE_Pthread -> Kokkos_ENABLE_THREADS
Kokkos_ENABLE_Cuda* -> Kokkos_ENABLE_CUDA*, where all appended options to following CUDA should be capitalized as well.

It looks like the occurrences of these options in Trilinos/packages (via git grep) are in build scripts (old?) and documentation

Kokkos_ENABLE_Serial
RELEASE_NOTES: Kokkos_ENABLE_Serial is ON), Tpetra uses Serial by default.
RELEASE_NOTES: - Tpetra_INST_SERIAL (Kokkos_ENABLE_Serial must be ON)

Kokkos_ENABLE_OpenMP
kokkos-kernels/BUILD.md: * Whether to pre instantiate kernels for the execution space Kokkos::OpenMP. Disabling this when Kokkos_ENABLE_OpenMP is enabled may increase build times.
kokkos-kernels/cmake/kokkoskernels_eti_devices.cmake: "Whether to pre instantiate kernels for the execution space Kokkos::Experimental::OpenMPTarget. Disabling this when Kokkos_ENABLE_OpenMPTarget is enabled may increase build times. Default: ON if Kokkos is OpenMPTarget-enabled, OFF otherwise."

tpetra/core/guide/src/Obtaining/Building.rst:- The Pthreads (Kokkos::Threads) back-end is a special case; it does not get enabled by default. This avoids surprises, because Trilinos enables its Pthreads TPL by default as long as it can detect it. Users may set the CMake option Kokkos_ENABLE_Pthread:BOOL=ON to enable use of Pthreads in Tpetra, and to make it default.

I can put in a PR using sed to update the naming, though any feedback on the testing script beforehand would be helpful as I don't want to disrupt anything actively used

Edit: Update to reflect the deprecation was pre-3.0 (previously I mistakenly stated this was pre-4.0)

[dalg24]

One clarification: this is not a Kokkos 4.0 change, these were already deprecated in v3.0

[ccober6]

@ndellingwood for the Tempus changes, please go ahead and make the replacement as these scripts are old and are likely not currently being used but may have some reference value. Thanks!

[bartlettroscoe]

I am sure everyone would appreciate a PR that addresses all of these. (Finding these is 90% of the work.)

[jhux2]

Can we just delete some of the obselete scripts instead? Some of the script are no longer used, e.g., the check-in script. I'll also wager that some of the scripts in cmake/ctest/drivers are for machines that no longer exist, e.g., apollo.

+1. These are still in the Git history so people can find them that way if they want.

[jhux2]

Here are the driver subdirectories and the last commit that touched them:

I'll open a separate issue for the driver scripts.

[ndellingwood]

I like the option of deleting the old scripts as well, I didn't want to jump the gun so I'll hold off on touching test script and for now I'll open a PR to update the naming convention in the various docs (test script updates / removal can be a separate PR)
Is there a way to label a PR indicating changes are to documentation only (and so the PR does not need to run through the full CI)?

@ndellingwood, not that I know of. That would create a backdoor way for developers to bypass the PR testing and get their PRs merged faster (which some people might use out of frustration).

There was discussion of allowing individual package's to label certain directories as not impacting the build or tests but that requires an extension to TriBITS (I can't seem to find that GitHub issue discussion).

The best strategy is to create one big PR with lots of changes and just accept that the PR builds and tests have to pass.

@bartlettroscoe ah, great point, thanks pointing that out!
