Test repo for apex and kokkos autotuning.
The steps to configure and build are the same as configuring/building APEX and Kokkos individually. For examples, see:
- generic-cuda.sh - generic NVIDIA workstation example
- perlmutter.sh - configure and build for an NVIDIA-GPU HPC system like Perlmutter.
- frontier.sh - configure and build for an AMD-GPU HPC system like Frontier.
Take note - the only CMake variable that is required is the -DKokkos_ENABLE_TUNING=ON setting, which enables the tuning support in Kokkos.
Another note - this repo uses a git submodule that is a fork/branch from the main Kokkos repository. That fork/branch contains the occupancy tuning support that has not yet been merged into the main repository, see PR 6788.
For slides with an overview of this repository, see http://www.nic.uoregon.edu/~khuck/kokkos/2024-Kokkos-Tuning-Tutorial/. To reproduce the mdrange_gemm results in the end of the tutorial, see tutorial.sh.
