LQCD SciDAC-4 Project


LQCD SciDAC-4 Project

The Lattice Quantum Chromo-Dynamics (LQCD) SciDAC-4 Project is supported by the U.S. Dept. of Energy Office of Nuclear Physics and the Office of Advanced Scientific Computing Research. The project is supporting the development of the software infrastructure to carry out scientific calculations to address fundamental questions in nuclear science. It is a collaboration of domain scientists, and computer scientists which aims to understand the structure of nuclear matter under extreme conditions, and how quarks and gluons are confined to build the matter that is observed in nature.

Accelerating QCD Gauge Generation on GPUs

SciDAC-4 Highlight, 2018-05-01

The generation of gauge configurations (samples of the strong force field in the vacuum) is the gating first step of nuclear and high energy physics calculations using lattice quantum chromodynamics (LQCD) generating the data on which subsequent calculations depend. Here, we demonstrate a 73x reduction in the GPU-hours required for the generation of such gauge fields moving from Titan to Summit, and incorporating new algorithms well suited to the new system. The improvement on Summit enables calculations which where hitherto considered out-of reach for reasons of computational cost, and will fundamentally re-shape how we will conduct our scientific campaigns in the future.
