Kokkos support in the TAU and APEX performance measurement tools #27

Open crtrott opened 7 months ago

TAU is a full-featured profiler/tracer that provides support for most parallel programming models and platforms, with Kokkos support enabled by default. APEX is a measurement library designed for asynchronous tasking runtimes that provides support for Kokkos and all available back ends, including HPX, and also provides auto-tuning support for Kokkos Team and MDRange execution policies.

Follow up comment... I tried out the occupancy tuning branch of old Kokkos, and while it does "something", I don't have a good example to work with. I am following up with the ArborX team to try with a case that they know should show improvement with different occupancy hints.
