A group of researchers at Fermi National Accelerator Laboratory have been granted 80 million processor hours at the Oak Ridge Leadership Computing Facility (OCLF) and the Argonne Leadership Computing Facility (ALCF) to better understand the interaction of these subatomic particles as they collide with the four fundamental forces of nature.
Collectively, this research falls under the banner of quantum chromodynamics, which involves finding ways in which basic interactions among gluons and quarks and the forces of nature can shed light on dominant theories in physics.
Protons, neutrons and electrons contain smaller particles that are called quarks and gluons, which have been the subject of numerous studies as scientists look for meaning how these subatomic particles interact.
The scientists behind the project will be reliant on the power of the Cray XT4/Xt5 at the OLCF and the IBM Blue Gene/P at the ALCF will allow the researchers to produce “and validate the high-precision lattice QCD calculations that are essential to the analysis of recently completed experiments in high-energy and nuclear physics and other studies currently in progress.” As a release from OLCF stated, “Simulations are used to relate the fundamental theoretical equations governing quarks and gluons to predictions of physical phenomena made in laboratories.”
The research teams will use Monte Carlo techniques to anticipate and the random movement of particles. As OCLF explained:
“Employing fundamentals from the Standard Model of subatomic physics, team members are exploring quark properties and dynamics. They are trying to determine the mass spectrum and coupling of strongly interacting particles and the electromagnetic properties of particles made up of interacting quarks (baryons and mesons) to create an understanding of a nucleon’s internal structure.”
The work was funded by the National Science Foundation and physics-related departments within the U.S. Department of Energy. According to Kathryn Jandeska, the use of the two supercomputing facilities has led to major advances in the field by yielding strong data to hold up to current theories in high-energy and nuclear physics.
More on the theories and source of the research can be found in this detailed writeup from Oak Ridge National Laboratory.
The Xeon Phi coprocessor might be the new kid on the high performance block, but out of all first-rate kickers of the Intel tires, the Texas Advanced Computing Center (TACC) got the first real jab with its new top ten Stampede system.We talk with the center's Karl Schultz about the challenges of programming for Phi--but more specifically, the optimization...
Although Horst Simon was named Deputy Director of Lawrence Berkeley National Laboratory, he maintains his strong ties to the scientific computing community as an editor of the TOP500 list and as an invited speaker at conferences.
Supercomputing veteran, Bo Ewald, has been neck-deep in bleeding edge system development since his twelve-year stint at Cray Research back in the mid-1980s, which was followed by his tenure at large organizations like SGI and startups, including Scale Eight Corporation and Linux Networx. He has put his weight behind quantum company....
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
