Accelerating Science with GPUs
Gauge Generation Benchmark
Strong (Hard) Scaling
• 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
TOP 500 (#364) Supercomputer
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)
ASCR Computing Challenge Award
250M core hours: biggest ever in May 2014

Measurement of the Parity-Violating Asymmetry

Longitudinally Polarized Electron Scattering
from Unpolarized Deuterium
(a [2C1u – C1d] +  [2C2u – C2d])
•
Provides a determination of the effective electron-quark
weak coupling combination 2C2u – C2d 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 C2q (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.

Gas Cerenkov ADC Sum (Channel)
Jefferson Lab in Newport News has reached a "major milestone" in its drive to double
the energy of its electron accelerator and become the only facility in the world
capable of answering key questions about quarks, the building blocks of matter.
