Lattice QCD on earth simulator
Abstract
We report on coding and performance of our polynomial hybrid Monte Carlo program on the Earth Simulator. At present the entire program achieves 25-40% efficiency. An analysis of overheads shows that a tuning of inter-node communications is required for further improvement.
