 Paper: Accelerating lattice QCD simulations with 2 flavours of staggered
fermions on multiple GPUs using OpenACC - a first attempt
“We present the results of an effort to accelerate a Rational Hybrid Monte Carlo (RHMC) program
for lattice quantum chromodynamics (QCD) simulation for 2 flavours of staggered fermions on
multiple Kepler K20X GPUs distributed on different nodes of a Cray XC30. We do not use CUDA
but adopt a higher level directive based programming approach using the OpenACC platform. The
lattice QCD algorithm is known to be bandwidth bound; our timing results illustrate this clearly, and
we discuss how this limits the parallelization gains. We achieve more than a factor three speed-up
compared to the CPU only MPI program.”
