13 Nov 2017 Oak Ridge - The U.S. Department of Energy's Office of Science announced 55 projects with high potential for accelerating discovery through its Innovative and Novel Computational Impact on Theory and Experiment (INCITE) programme. The projects will share 5.95 billion core-hours on three of America's most powerful supercomputers dedicated to capability-limited open science and support a broad range of large-scale research campaigns from infectious disease treatment to next-generation materials development.
These awards allocate the multi-petascale computing resources of two DOE Leadership Computing Facilities at Argonne and Oak Ridge National Laboratories. The two centres jointly manage the INCITE programme as is the primary means of accessing their resources. INCITE proposals are awarded on a competitive basis to researchers from academia, government research facilities, and industry. The average award is more than 108.1 million core-hours - with some awards of up to several hundred million core-hours - on systems capable of quadrillions of calculations per second.
"DOE's INCITE programme gives researchers access to computational resources to ambitiously address some of the world's most formidable scientific research problems", stated James Hack, director of the National Center for Computational Sciences (NCCS), home to the Oak Ridge Leadership Computing Facility (OLCF), a DOE Office of Science User Facility in Oak Ridge, Tennessee. "These scientific projects would not be possible without access to DOE leadership computing resources, and we're gratified to be able to partner with these outstanding research teams to enable fundamental advances in our understanding of the amazing world in which we live."
Domain scientists and computational scientists at the leadership centers partner with each INCITE project, aiding in code and methods development, optimization, streamlining workflow, troubleshooting unforeseen problems, and assisting with data analysis and visualization.
"Researchers seek out the INCITE programme to support their research through access to three of the world's fastest supercomputers, but our facilities also provide significant staff expertise and support to help them achieve their goals", stated Michael E. Papka, director of the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility just outside Chicago. "This support helps ensure investigators can maximize their time on our leading-edge systems."
The ALCF's Mira supercomputer is a 10-petaflops IBM Blue Gene/Q system with 49,152 compute nodes and a power-efficient architecture. ALCF's Theta is a 9.65-petaflops Cray XC40 system based on the second-generation Intel Xeon Phi processor. 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, expansions, and advances in computing power, demand for leadership-class resources such as Mira, Theta and Titan continues to exceed availability, and, once again, more applications for time were made to INCITE than were awarded.
