KNOXVILLE—Jack Dongarra, distinguished professor of computer science at the University of Tennessee in Knoxville, is being honored for his leadership in high performance computing.

He will receive the Association for Computing Machinery-Institute for Electrical and Electronics Engineers Computer Society Ken Kennedy Award on Nov. 19 in Denver at SC13, the International Conference on High Performance Computing.

Dongarra, who is also a distinguished research staff member at Oak Ridge National Laboratory, is being recognized for designing and promoting standards for mathematical software used to solve numerical problems common to high-performance computing. His work has led to the development of major software libraries of algorithms and methods that boost performance and portability in high-performance computing environments. [Read more…]

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.
