Accelerating Science with GPUs Before: Used CPU + GPU solver library for LQCD Analysis ( >95% work in solver ) Gauge Generation uses solvers less - smaller gain from only accelerating solver QDP-JIT layer moves entire calculation to GPU (+ we still use GPU solver library) 2x-5x speedup over GPU solver library alone, 3.7x-11x speedup over CPU alone Data from: F. Winter ( JLab ), M. A. Clark (NVIDIA), B. Joo ( JLab ), R. Edwards ( JLab ) - Accepted for IPDPS’14 conference Applicable to leadership GPU systems such as DOE Titan (ORNL) and NSF Blue Waters (NCSA - University of Illinois) Strong (Hard) Scaling Gauge Generation Benchmark TOP 500 (#364) Supercomputer (for only $750K!)

Measurement of the Parity-Violating Asymmetry in eD Deep Inelastic Scattering Provides a determination of the effective electron-quark weak coupling combination 2C 2u – C 2d that is five times more precise than before. It is the first experiment to isolate, when combined with previous experiments like Q-weak, a non-zero C 2q (at 95% confidence level). This coupling describes how much of the mirror-symmetry breaking in the electron-quark weak interaction originates from the quarks' spin preference. The result provides a mass exclusion limit on the electron and quark compositeness and contact interactions of ~5 TeV .
