Photos: The world's 25 fastest supercomputers

US back on top

The second of the TOP500 supercomputer lists of 2018 is out, and the US has continued to grow its lead over competing Chinese supercomputers.

The new TOP500 list is led for the second time by Summit, a US Department of Energy supercomputer capable of performing 122 quadrillion floating-point operations per second.

Another US-based supercomputer, Lawrence Livermore National Laboratory's Sierra, has overtaken the previous number two, the Chinese National Computing Center's Sunway TaihuLight, putting the US in the top two spots.

While there are many changes in the top 25, most of machines still rely on vast numbers of Intel CPUs, aided by Nvidia GPUs or many-core Intel Xeon Phi processors.

Here are the 25 most powerful machines in the TOP500 list of supercomputers.
