abstract = {Lattice quantum chromodynamics (QCD) is a numerical
approach to studying the interactions of quarks and gluons,
where the fundamental eqautions governing their interactions
are discretized to a four dimension spacetime lattice. One
of the most costly computations is the inversion of the
lattice Dirac operator, a large sparse matrix. Calculating
this inversion with iterative solvers leads to many
applications of that operator. This study builds on previous
work where we implemented the staggered fermion Dirac
operator as a benchmark in Kokkos. We investigate the
effects of the tiling size in combination with the use of a
4D MDRangePolicy and 7D Views.},
