Performance Portability of a Wilson Dslash Stencil Operator Mini-App Using Kokkos and SYCL

Conference ·
; ; ; ; ; ; ;

We describe our experiences in creating mini-apps for the Wilson-Dslash stencil operator for Lattice Quantum Chromodynamics using the Kokkos and SYCL programming models. In particular we comment on the performance achieved on a variety of hardware architectures, limitations we have reached in both programming models and how these have been resolved by us, or may be resolved by the developers of these models.
