The Chroma Software System for Lattice QCD

The Chroma Software System for Lattice QCD

We present the Chroma software system [1] for lattice QCD (LQCD) calculations. Chroma aims to provide a computational LQCD toolbox which is flexible, portable and efficient on a wide range of architectures from desktop workstations to clusters, commercial machines and new architectures such as the QCDOC [2] Development on Chroma started at the JLab for the U.S. lattice community, in particular ...

Lattice QCD with Commodity Hardware and Software

Large scale QCD Monte Carlo calculations have typically been performed on either commercial supercomputers or specially built massively parallel computers such as Fermilab’s ACPMAPS. Commodity computer systems offer impressive floating point performance-tocost ratios which exceed those of commercial supercomputers. As high performance networking components approach commodity pricing, it becomes...

Opportunities for Lattice QCD Thermodynamics Lattice QCD Executive Committee

Over the next decade high performance computing resources will reach the petaflops scale. Coupled with current and planned experiments at RHIC, FAIR, and the LHC, these computational resources will offer significant opportunities for the advancement of our understanding of the properties of strongly interacting matter at high temperatures and densities. We describe expected quantitative and qua...

Lattice Qcd for Novices

These lectures are for novices who are interested in learning how to do lattice QCD simulations. My intent is to describe in detail everything that one needs to know in order to create and run a simple lattice QCD simulation. My focus here is not on lengthy derivations or detailed comparisons of algorithms. Rather I want to introduce a set of simple ideas and techniques that one can implement i...
