Performance Portability Libraries▶ A solution to keep one codebase for multiple backends
● E.g. CPU, NVidia GPU, <accelerator xyz>
▶ Investigation started and is still ongoing
● Several products investigated: OpenACC, Raja, Kokkos, Alpaka, SYCL, OpenMP, ...
▶ At the moment three credible alternatives:
● Kokkos - Sandia Lab
● Alpaka - Helmholtz-Zentrum Dresden
● SYCL - Khronos Group
▶ Need to gain more experience to make sensible choice
● Patatrack incubator and other efforts
