Though the U.S remains the leader, the current top supercomputer is a new machine as of this month, displacing the previous champion, the IBM Sequoia. The U.S. reclaimed the crown of world’s fastest in June of this year with the Linux-powered Sequoia, which is installed at the Lawrence Livermore National Lab.
Sequoia’s top spot came after a three year absence for the U.S. in terms of holding the global supercomputing crown. While Sequoia originally clocked in at 16.32 petaflops per second, it’s now been displaced by the Cray-built Titan system, which clocks in at 17.59 Petaflops per second.
