China’s Tianhe-2 Supercomputer Maintains Top Spot on List of World’s TOP500 Supercomputers

FRANKFURT, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.— For the sixth consecutive time, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, has retained its position as the world’s No. 1 system, according to the 46th edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers. Overall, change at the top of the list is again minor, with only two new systems in the Top 10 -- the Trinity supercomputer built by Cray and jointly deployed by the Department of Energy’s (DOE) Los Alamos and Sandia national laboratories, and the Hazel-Hen system built by Cray and installed at the HLRS - Höchstleistungsrechenzentrum Stuttgart in Germany.

Jack Dongarra on TOP500: Past, Present, and Future

As the TOP500 project works its way through its third decade of its life, there is talk of expanding the effort to include new metrics to Linpack. There is no one better to discuss this topic than veteran TOP500 co-author, Jack Dongarra, who was present at the birth of list in 1992.

A Chat with TOP500 Co-Author Horst Simon

Horst Simon is the Deputy Director of Lawrence Berkeley National Laboratory. Outside his executive role at the lab, Simon is a highly respected mathematician in the high performance computing (HPC) community. Within the HPC community, he plays another significant role as the co-editor of the TOP500 project.

Forecast Calls for GPU Packed Supercomputer Nodes

In the course of tracking commercial and research supercomputers here at The Platform, it has become apparent that this is the year for massive refreshes and updates to existing weather prediction systems.

This Hospital Computer Knows When Your Days Are Numbered

Chalk “predict death” off the list of “what computers can’t do.” A supercomputer at Beth Israel Deaconess Medical Center in Boston, Mass., can decipher the likelihood of a patient’s imminent demise with uncanny accuracy.

How One HPC Center Learned to Count

By John West; Given the impact of HPC, it is important that we do everything we can to ensure that we are including the best solutions possible in the technologies that we build, and for that we need to be sure we are asking the broadest sampling of people for their best ideas.
