The allocations come from the Innovative and Novel Computational Impact on Theory and Experiment, or INCITE, programme. Through it, the world's most advanced computational research projects from academia, government and industry are given access to the Department of Energy's (DOE's) leadership computing facilities at Oak Ridge and Argonne national laboratories.
"The INCITE programme addresses the largest, most computationally pressing projects in science and engineering", stated Michael Papka, director of the Argonne Leadership Computing Facility (ALCF). "These allocations enable state-of-the-art science in a wide range of domains."
"The INCITE programme - which is celebrating its 10-year anniversary - provides researchers with the opportunity to make scientific breakthroughs in fields that would not be probable or even possible without access to the most powerful available supercomputers", stated James Hack, director of the National Center for Computational Sciences, which houses the Oak Ridge Leadership Computing Facility (OLCF).
When INCITE made its first awards in 2004, three projects received an aggregate 5 million hours on DOE supercomputers. Today's collective allocation of nearly 6 billion core hours represents a 1,000-fold growth in resources provided to researchers. The average award is more than 75 million core hours - with individual awards of up to several hundred million core hours - on systems capable of quadrillions of calculations each second.
The ALCF's primary leadership computing resource is Mira, a 10-petaflops IBM Blue Gene/Q system with 49,152 compute nodes and a power-efficient architecture. The OLCF's Titan supercomputer is a 27-petaflops Cray XK7 hybrid system, employing both CPUs and energy-efficient, high-performance GPUs in its 18,688 compute nodes.
Despite continued upgrades and expansions, demand for leadership computing facilities surpasses availability, and DOE's world-class facilities continue to attract new users. This year INCITE applications greatly exceeded awards.
"INCITE is one of the main programs that gives researchers access to some of the country's leadership computing facilities", stated Julia White, INCITE manager at DOE's Leadership Computing Facilities. "Large supercomputer awards like this also give researchers support from computer experts who design code and optimize it for the supercomputers, which helps ensure that the scientists who run simulations on DOE's machines can take full advantage of their enormous processing power."
Supercomputer simulations create a detailed picture of complex phenomena by relying on codes packed with math equations. Highlights of the 2014 allocations include the following:
