Research teams receive computing time on the Titan supercomputer

Every year, the US Department of Energy’s (DOE’s) Office of Advanced Scientific Computing Research (ASCR) provides scientists with time on world-class computational resources across the country through the ASCR Leadership Computing Challenge (ALCC). The ALCC program grants 1-year awards to energy-related research efforts with an emphasis on high-risk, high-reward simulations in line with DOE’s mission.

The ALCC program distributes time among multiple DOE Office of Science User Facilities, allocating up to 30 percent of the HPC resources at the Oak Ridge Leadership Computing Facility (OLCF) at DOE’s Oak Ridge National Laboratory (ORNL) and Argonne National Laboratory’s Argonne Leadership Computing Facility (ALCF), as well as up to 10 percent at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory.

ASCR manages all three user facilities, which each contain powerful supercomputers. Previous ALCC project recipients have leveraged these high-performance computing (HPC) systems to advance scientific and technological research in fields such as nuclear physics, energy efficiency, and materials science.

In 2018, 14 projects have earned a combined 729.5 million core hours on Titan, the OLCF’s 27-petaflop supercomputer, to continue that tradition of innovation and discovery. Using Titan, teams of scientists will conduct experiments, collect data, and analyze results in support of various research topics, from studying biological processes in microbial ecosystems to developing new cosmological simulations for studying the history of the universe.

Projects given time at the OLCF this year, which received awards ranging from 5 million to 100 million processor hours, are listed below. Some projects have additional computing time at the ALCF and/or NERSC.
