10 of the world's fastest supercomputers

The semi-annual Top500 ranking of the world’s fastest supercomputers is in for fall 2018 with China claiming 227 of the 500 spots on the list, although it managed to take just two places in the top 10. The United states took five of the top 10, including first and second place. New to the Top500 rankings at number 205 is Astra, an HPE-built machine at Sandia National Laboratories that is the first powered by ARM chips to make the list. The top 10 highlighted in this slideshow demonstrate what might become available in corporate data centers.

IBM Sequoia is a petascale Blue Gene/Q supercomputer

10. Sequoia

This U.S. Department of Energy computer was the world’s most powerful in 2012 and has managed to cling to the top 10 ever since. This past summer Sequoia ranked number 8, but it dropped to number 10 in the latest list. It is an IBM BlueGene/Q system that can deliver 17.17 petaflops using 1,572,864 cores and peaks out at 20.13 petaflops.

5. Piz Daint

Piz Daint continued its steady ascent up the Top500 list, reaching number 5 this fall after listing number 6 earlier this year. It started its climb back in 2012 when it jumped into the Top500 at number 114. Stationed at the Swiss National Supercomputing Centre in Lugano, Switzerland, it is the most powerful supercomputer in Europe at 21.2 petaflops. It’s powered by Intel Xeon processors and NVIDIA Tesla P100 GPUs.
