Argonne scientists were awarded projects in nuclear physics, high energy physics, and Earth system model development through the U.S. Department of Energy’s Scientific Discovery through Advanced Computing program.
What are the basic building blocks of matter? How did the universe evolve? What will happen to Earth’s climate in the future? These are questions that high performance computers can answer.
The U.S. Department of Energy (DOE) announced the funding of new five-year projects under its Scientific Discovery through Advanced Computing (SciDAC) program in nuclear physics, high energy physics and Earth system model development. Scientists at DOE’s Argonne National Laboratory have been selected to lead two and participate in eight collaborative projects using advanced high performance computers.
“The SciDAC program is an excellent example of the kind of uniquely impactful work that can be performed by cross-disciplinary teams joining hands across scientific domain boundaries.” — Salman Habib, director of Argonne’s Computational Science division.
The program brings together many of the nation’s top researchers to develop new computational methods for tackling some of the most challenging scientific problems. The projects will be conducted by collaborative teams led by DOE national laboratories.
“The fact that Argonne is involved in nearly all SciDAC projects is a testament to the expertise of our staff. Together with our partners, we will bring the power of supercomputing to the study of some of the smallest things in nature —atomic nuclei — and the largest, the cosmos,” said Kawtar Hafidi, who oversees Argonne’s research programs in nuclear and high energy physics as associate laboratory director for Physical Sciences and Engineering.
The SciDAC program in nuclear physics funded three multi-institution projects for a total of $35 million. Researchers from Argonne will participate in all three projects and lead one. Leading “Femtoscale Imaging of Nuclei Using Exascale Platforms,” Ian Cloët, an Argonne theoretical physicist, will work with partners from DOE’s Thomas Jefferson National Accelerator Facility and Virginia Polytechnic Institute and State University to develop a new framework for extracting 3D images of nucleons from experimental data. Together they are hoping to find new discoveries on the nature of matter at extremely small length scales — the so-called femtoscale, corresponding to a quadrillionth of a meter.
The SciDAC program in high energy physics funded five projects, for a total of $30 million. One project is led by Argonne physicist and computational scientist, Katrin Heitmann. (Other participating institutions are DOE’s Lawrence Berkeley and Los Alamos national laboratories and Virginia Tech.) “Enabling Cosmic Discoveries in the Exascale Era” will use exascale supercomputers to create models and simulations from new cosmological survey datasets. It will study the universe’s origin and evolution. Combined with observations, the model predictions are crucial to exploring new insights into dark matter and dark energy.
The two Argonne-led projects will support pioneering research on DOE’s exascale supercomputers including Aurora, the next-generation system being built at the Argonne Leadership Computing Facility, a DOE Office of Science user facility at Argonne.
“The SciDAC program is an excellent example of the kind of uniquely impactful work that can be performed by cross-disciplinary teams joining hands across scientific domain boundaries,” said Salman Habib, director of Argonne’s Computational Science division. “Much of the future of science rests on the success of endeavors that bring together cutting-edge computing and innovative scientific ideas.”
