A new Chinese supercomputer is theoretically twice as fast as the Titan supercomputer at Oak Ridge National Laboratory, and it could bump Titan from the No. 1 spot on the Top 500 list that will come out on June 17, one of the co-authors of the list said Wednesday.
Titan, which reached the No. 1 spot on the semiannual Top 500 list in November, has a theoretical peak of 27 petaflops, or roughly 27,000 trillion calculations per second.
The Chinese supercomputer, Tianhe-2, also known as TH-2 or Milkyway-2, has a theoretical peak of 54.9 petaflops. It also has about twice as much memory as the Titan system, said Jack Dongarra, a Top 500 co-author, University of Tennessee faculty member, and distinguished research staff member in ORNL’s Computer Science and Mathematics Division.
