The U.S. may need a more powerful supercomputer.
Two Chinese supercomputers and an upgraded supercomputer in Switzerland rank ahead of the U.S. in a biannual list of top supercomputers released Monday by the TOP500 organization, which tracks supercomputer speeds.
It is only the second time that the U.S. absent from the top 3 most powerful supercomputers since the organization started compiling the rankings 24 years ago. In the previous ranking, published in November, the top U.S. supercomputer — located at Oak Ridge National Laboratory in Oak Ridge, Tenn. — was No. 3.
“The only other time this occurred was in November 1996, when three Japanese systems captured the top three spots,” the organization said in a statement.
But it wasn’t all bad news for the U.S.
The U.S. has five of the top 10 supercomputers on the list, the most of any other country. Additionally, the U.S. has 169 supercomputers in the top 500, followed by China with 160.
As for the companies supplying the parts for the supercomputers, Intel is the biggest with 464 of the top supercomputers using its processors. IBM and its Power processors are installed in 21 supercomputers, followed by AMD’s chips, which are used in six supercomputers.
Nvidia’s GPU chips, which are specialized for heavy data crunching like deep learning, are being used in 91 supercomputers to make them more powerful beyond what the typical chips used inside. For example, the Swiss National Supercomputing Center outfitted its supercomputer with Nvidia’s chips, which caused the machine to double its performance and climb from No. 8 to the No. 3 in the supercomputer rankings.
