| Summary: | <p dir="ltr">Laplacian Heaviside (LapH) quark-field smearing greatly facilitates the computation of temporal correlation functions in lattice QCD involving multi-hadron operators. Hadron scattering studies in lattice QCD require the evaluation of such correlation functions. Many low-lying core routines needed in lattice QCD have been accelerated using GPUs in a library known as QUDA, but tasks involving LapH smeared quarks have not been available. Development of GPU kernels into QUDA for such tasks is presented, as well as the development of quda_laph, a user interface and driver code to carry out hadron scattering workflows involving LapH smeared quarks in lattice QCD.</p> |
