IBM Sequoia supercomputer is the fastest in the world, ahead of Fujitsu K 1.5 times

    New Top 500 List Leader Built at Livermore National Laboratory . Its performance is 16.32 petaflops, which is one and a half times more than the previous champion - Fujitsu K with its 10.51 petaflops. At the same time, it consumes 7.9 megawatts compared to 12.6 for Fujitsu. IBM Sequoia is built on the Blue Gene / Q architecture and contains 1.6 million cores and 1.6 petabytes of memory - a gigabyte per core. The computer occupies 96 racks. It runs on Linux.



    IBM is a leading manufacturer of supercomputers. Among the 500 most productive computers in the world, 213 are made by IBM. Modern supercomputers consume so much electricity that their energy efficiency is becoming as important as absolute performance. There is even a list of Green 500 , the place in which depends on the number of megaflops per watt of electricity. For Sequoia, this figure is more than 2000, which means it will occupy one of the first places on the list. Fujitsu K now ranks 32nd with a score of 830.18 megaflops / watt.

    In addition to reducing electricity consumption, attempts are also made to utilize the heat generated by supercomputers during operation. So, another IBM machine - SuperMUC, installed in the Leibniz supercomputer center near Munich, uses fully water cooling. Hot water at the outlet is used for heating and hot water supply of the surrounding buildings. Such a cooling system increases overall energy efficiency by 40%. SuperMUC is the fastest computer in Europe and ranks 4th in the Top 500.
