IBM’s Sequoia named world’s fastest supercomputer
IBM's Sequoia has taken the top spot on the list of the world's fastest supercomputers, marking the first time since 2009 that the US has claimed the title.
According to the latest TOP500 rankings, the system was able to achieve 16.32petaflop/s on the Linpack benchmark using 1,572,864 cores. The result relegated Fujitsu's K into second place after two years at the top.
The supercomputer was installed at the Department of Energy's Lawrence Livermore National Laboratory and was found to be 55% faster than K, which clocked in at 10.51Pflop/s using 705,024 SPARC64 processing cores. It was also said to be one of the most energy efficient computers on the list, consuming 7.9MW of power to K's 12.7MW.
The rankings show that IBM produced 213 of the systems featured on the list (42%), compared to HP which had 138 (27%). 372 of the systems (74.4%) featured Intel processors.
