Lattice quantum chromodynamics (QCD) is a first principles approach to studying the interaction of quarks and gluons. The calculation of observables in lattice QCD requires many different operations between multidimensional arrays of various ranks. In this talk, I will describe an implementation of expression templates using Kokkos that allows for lattice QCD practitioners to simply implement linear algebra operations while avoiding temporaries for views of arbitrary rank. This abstraction has the potential to promote high productivity in the development process. The performance of various benchmarks on different architectures will also be discussed.

Travis Whyte

Postdoc, Jülich Supercomputing Centre

I graduated from Baylor University with a Ph.D. in Physics, focusing on algorithmic improvements for lattice QCD simulations. Since then, I have continued to work in the field, focusing on improving iterative solvers, scattering simulations and HPC software development.
