Summit — the world’s most powerful supercomputer, with a peak performance of 200,000 trillion calculations per second, or 200 petaflops* peak performance — was announced<\/a> June 8 by the U.S. Department of Energy\u2019s\u00a0Oak Ridge National Laboratory<\/a> (ORNL).<\/p>\n

The previous leading supercomputer was China’s Sunway TaihuLight<\/a>, with 125 petaflops peak performance.**<\/p>\n

Summit will enable researchers to apply techniques like machine learning and deep learning to problems in human health such as genetics and cancer, high-energy physics (such as astrophysics and fusion energy), discovery of new materials, climate modeling, and other scientific discoveries that were previously impractical or impossible, according to ORNL.<\/p>\n

\u201cIt\u2019s at least a hundred times more computation than we\u2019ve been able to do on earlier machines,\u201d said ORNL computational astrophysicist Bronson Messer.<\/p>\n

Summit’s IBM system has more than 10 petabytes (10,000 trillion bytes) of memory and 4,608 servers — each containing two 22-core IBM Power9 processors and six NVIDIA Tesla V100 graphics processing unit (GPU) accelerators. (\u201cFor IBM, Summit represents a great opportunity to showcase its Power9-GPU AC922 server to other potential HPC \u00a0and enterprise customers,\u201d notes Michael Feldman<\/a>, Managing Editor of Top 500 News<\/em>.)<\/p>\n

Exascale next<\/strong><\/p>\n

Summit will be eight times more powerful than ORNL\u2019s previous top-ranked system, Titan. For certain scientific applications, Summit will also be capable of more than three billion billion mixed-precision calculations per second, or 3.3 exaops.<\/p>\n

Summit is a step closer to the U.S. goal of creating an exascale (1 exaflop* or 1,000 petaflops) supercomputing system by 2021. (However, China has multiple exaflop projects expected to be running a year or more before the U.S. has a system at that level, according to EE Times<\/a>.)<\/p>\n

Summit is part of the Oak Ridge Leadership Computing Facility at DOE\u2019s Office of Science <\/a>.<\/p>\n

* A petaflop is 1015<\/sup> (1000 trillion) floating point operations per second (\u201cfloating point\u201d refers to the large number of decimal-point locations required for the wide range or numbers used in scientific calculations, including very small numbers and very large numbers). An exaflop is 1018<\/sup> floating point operations per second.<\/em><\/p>\n

** The \u201cpeak\u201d rating refers to a supercomputer\u2019s <\/em>theoretical maximum performance. A more meaningful measure is \u201cRmax\u201d — a score that describes a supercomputer’s maximal <\/em>measured performance on a Linpack<\/em> benchmark<\/a>. Rmax for the Summit\u00a0<\/em>has not yet been announced.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
