For the fourth consecutive time, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, has retained its position as the world’s number one system.

The rankings are from the 44th edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers, which was announced Monday in Mannheim, Germany; Berkeley, California; and Knoxville.
