IBM Sequoia supercomputer has become the fastest in the world, having overtaken Fujitsu K by a factor of 1.5
The new leader of the Top 500 list is 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 c of its 10.51 petaflops. At the same time, it consumes 7.9 megawatts versus 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 - one gigabyte for each core. The computer takes 96 racks. It works under Linux OS.
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 becomes as important an indicator 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 take one of the first places in the list. Fujitsu K now ranks 32nd with a score of 830.18 megaflops / watt.
In addition to reducing electricity consumption, attempts are being 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 surrounding buildings. Such a cooling system increases overall energy efficiency by 40%. The SuperMUC computer is the fastest in Europe and takes the 4th place in the Top 500.
