Abstract
Lattice Quantum Chromodynamics (Lattice QCD) is a framework for calculating
the properties of fundamental particles made up of quarks and gluons. It is
also a "grand challenge" subject, profitably employing a significant
fraction of the cycles at many of the world’s largest computing centers. In
this talk, I will discuss the ways in which graphics processing units (GPUs)
and related architectures are promising to revolutionize the way many
lattice calculations are performed. In particular, I will discuss "QUDA," a
library of linear solvers tailored for QCD and written using NVIDIA’s "C for
CUDA" API. I will describe the strategies we employed to obtain high
performance on a single GPU and the challenges we face as we build on this
foundation to use many GPUs in parallel.
Bio
Ron Babich's research focuses on fundamental questions in particle physics,
which he addresses using the tools of high performance computing. Ron
received his Ph.D. in Physics from Boston University in 2009 and has
accumulated significant experience developing optimized codes on a range of
platforms, from commodity clusters to tightly coupled machines such as the
IBM Blue Gene series and emerging architectures such as graphics processing
units. His interests also extend to the practical problem of configuring
cost-effective and scalable systems that couple the power of GPUs with
high-speed interconnects.
