ORNL’s Titan supercomputer retains No. 2 ranking

titanOak Ridge National Laboratory’s Titan supercomputer, a Cray XK7 system capable of more than 17.5 petaflops — or 17.5 million billion calculations per second — remains No. 2 on the new TOP500 list of the world’s fastest supercomputers. The new rankings were released at the Supercomputing Conference in Frankfurt, Germany.

China’s Tianhe-2 still resides atop the list with a capability of more than 33 petaflops. The Tianhe-2 system was developed at China’s National University of Defense Technology.

The TOP500 rankings are released every six months, and China has had the top supercomputer for five consecutive times. Jack Dongarra of the University of Tennessee and ORNL is one of the experts who compiles the list.

Here is the complete list of the world’s top supercomputers.

The only new entry in the top 10 is a Cray supercomputer in Saudi Arabia — called Shaheen II — with a benchmark of about 5.5 petaflops. Four of the 10 fastest supercomputers are located at Department of Energy labs in the U.S.
