The U.S. Department of Energy’s (DOE) Advanced Scientific Computing Research (ASCR) Leadership Computing Challenge (ALCC) has awarded supercomputing time at the Argonne Leadership Computing Facility (ALCF) to 16 projects that will pursue advances in areas ranging from battery research to climate modeling to fusion energy.

Each year, the ASCR program, which manages some of the world’s most powerful supercomputing facilities, selects ALCC projects in areas that aim to further DOE mission science and broaden the community of researchers capable of using leadership computing resources.

The ALCC program allocates computational resources at ASCR’s supercomputing facilities to research scientists in industry, academia, and national laboratories. In addition to the ALCF located at DOE’s Argonne National Laboratory, ASCR’s supercomputing facilities include the Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory, and the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. The ALCF, OLCF, and NERSC are DOE Office of Science user facilities.

The 16 projects awarded time on the ALCF’s Theta and Polaris systems are listed below. Some projects received additional computing time at OLCF and/or NERSC. The one-year awards begin July 1.

==========

The Argonne Leadership Computing Facility provides supercomputing capabilities to the scientific and engineering community to advance fundamental discovery and understanding in a broad range of disciplines. Supported by the U.S. Department of Energy’s (DOE’s) Office of Science, Advanced Scientific Computing Research (ASCR) program, the ALCF is one of two DOE Leadership Computing Facilities in the nation dedicated to open science.

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America's scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy's Office of Science.

The U.S. Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit https://energy.gov/science
