KINGSTON, R.I. \u2013 November 20, 2020 \u2013 How fast can a supercomputer calculate? Today’s top supercomputers can do many\u00a0quadrillion (1 followed by 15 zeros) calculations in a single second. If every person on the planet were to perform a calculation in a second, it would take the human population months to complete what a top supercomputer can do in a single second.<\/p>\n

A 溏心vlog免费B站 professor and two colleagues from other institutions will soon have access to just such a supercomputer.<\/p>\n

溏心vlog免费B站\u2019s founding Director of Research Computing and Professor of Physics Gaurav Khanna and his colleagues\u00a0 Zachary Grant, Ph.D., a researcher at Oak Ridge National Laboratory, and Professor Sigal Gottlieb of University of Massachusetts Dartmouth were awarded 880,000 core-hours of\u00a0supercomputing\u00a0time on Oak Ridge National Lab’s\u00a0Summit\u00a0<\/em>supercomputer.<\/p>\n

Summit\u00a0<\/em> is the fastest supercomputer in the US today, capable of performing 200 quadrillion calculations in one second. Built by IBM and funded by the United States Department of Energy, Summit<\/em> consists of 9,216 POWER9 processors and 27,648 Nvidia Tesla graphic processing units (GPUs)\u00a0and consumes 13 megawatts of power.<\/p>\n

The trio received the maximum awarded Directors’ Discretionary allocation in a highly competitive process. The allocation is\u00a0equivalent to\u00a0$132,200 of funding according to the Department of Energy. Their research project, “Mixed-Precision WENO Method\u00a0for\u00a0Hyperbolic PDE Solutions<\/em>” involves implementing and evaluating different computational methods for black hole\u00a0simulations.<\/p>\n

Khanna’s research is in the area of black hole\u00a0physics and gravitational waves. These waves are “ripples” in the fabric of space-time\u00a0that were recently discovered by the United States Laser Interferometer Gravitational-Wave Observatory (LIGO)\u00a0project, a century after they were theoretically predicted by Einstein. The University is a member of the LIGO Science Collaboration, led by professor Robert Coyne in the 溏心vlog免费B站 Department of Physics.<\/p>\n

Professor Khanna works on a next generation version of LIGO, a space-borne gravitational wave detector, called LISA, led by the European Space Agency and NASA. His research is funded by the National Science Foundation. This significant allocation of supercomputing time will support research activities at 溏心vlog免费B站 in the area of black hole physics for years to come.<\/p>\n

“One of my goals is to bring to 溏心vlog免费B站 the experience of accessing and effectively utilizing the national computing infrastructure, including the largest supercomputing systems on the planet like ORNL Summit,” said Khanna.<\/p>\n

He plans to leverage national and regional infrastructure to support 溏心vlog免费B站 faculty research efforts, while also investing in computational resources on-campus.<\/p>\n","protected":false},"excerpt":{"rendered":"
