Description

Repairs issues from PR #1533 for directory work.
Resolved CUDA tests and Albany link failure.

Motivation and Context

Restore CUDA builds and Albany build.

How Has This Been Tested?

On white:
source $TRILINOS_DIR/cmake/std/atdm/load-env.sh cuda-9.2-gnu-7.2.0-release-debug
$ cmake
-GNinja
-DTrilinos_CONFIGURE_OPTIONS_FILE:STRING=cmake/std/atdm/ATDMDevEnv.cmake
-DTrilinos_ENABLE_TESTS=ON -DTrilinos_ENABLE_Zoltan2=ON
$TRILINOS_DIR
$ bsub -x -Is -q rhel7F -n 16 ctest -j16

On clang parallel and serial.

Checklist

My commit messages mention the appropriate GitHub issue numbers.
My code follows the code style of the affected package(s).
My change requires a change to the documentation.
I have updated the documentation accordingly.
I have read the code contribution guidelines for this project.
I have added tests to cover my changes.
All new and existing tests passed.
No new compiler warnings were introduced. Except CUDA.
These changes break backwards compatibility.

Switch Kokkos::unordered_map to std::unordered_map as further work needs to be done resolving types first. Copy murmur hash code in directly to remove link error for Albany. To remove/refactor later for Kokkos development. Disabled one new test that needs modification to work with unordered map.

You could have just used a HostSpace version of Kokkos::UnorderedMap, but just using a standard library class should be fine too.

@mhoemmen Thanks for reviewing this. Did not think of doing the host space which would have been easier. We are planning to do further development to use kokkos so eventually I'll be converting this back once I resolve some std::vector issues.

The idiomatic way to have a static (internal linkage) function in C++ is to put it in an anonymous namespace, like this:

namespace { // (anonymous) void foo () { whatever_code (); } } // namespace (anonymous)

I will fix this.

Shouldn't the above changes have fixed the build errors?

This was just one of the issues - but was a new test with some complications so I just disabled. However if i use your suggestion of Host space for the unordered map I should be able to restore this as well.

Approving for the sake of Albany, but does that disabled test actually work now?

@mhoemmen Thanks for the assistance on the review. I will make a follow up PR to implement your suggested changes.

@MicheldeMessieres Thanks! Does the test actually build and pass with CUDA?

@mhoemmen To confirm tests were building and passing with CUDA which I tested on white. The PR fix is now merged.

MicheldeMessieres · 2019-01-24T12:58:49Z

@kddevin @mhoemmen I will set up another PR today to restore the new test we added and implement Mark's suggestions. Using the Kokkos unordered map with HostSpace also worked fine for the CUDA white build.

mhoemmen · 2019-01-24T16:29:20Z

@MicheldeMessieres As long as the test is restored and passes with CUDA, I'm fine. It's not clear whether Kokkos::UnorderedMap would be faster for the sequential CPU case, so unless you plan on parallelizing the code, I wouldn't worry about it.
