ISC Beyond the Hans Meuer Era (HPCWIRE)

"Hans Werner Meuer (1936 – 2014†) and his legacy need little introduction within the high-performance computing (HPC) community. In Europe, he is known as the “Father of European supercomputing.” Hans, as he was fondly known in the community, became involved in data processing in 1960 and for the next 54 years of his life, he played various roles in the supercomputing world."

Who Are the Top500 List Countries?

Since June of 1993, the Top500 List has been presenting information on the world’s 500 most powerful computer systems. The statistics about these systems have proven to be of substantial interest to computer manufacturers, users and funding authorities. While interest in the list is focused on the computers, less attention is paid to the countries hosting them. Let’s take a look at the Top500 List countries. Who are they? How might one characterize them?

Call for Participation in the Top500 List

Submission deadline for the June release of the TOP500 List which will be released on Monday, June 23rd during the the International Supercomputing Conference (ISC) is May 18th (23:59 PST). All system reported have to be installed by June 1st. The last date for submitting linkpack updates is also June 1st.  For more details, please take a look at the submission guidelines and the instructions of the submission process.

China’s Tianhe-2 Supercomputer Takes No. 1 Ranking on 41st TOP500 List

MANNHEIM, Germany; BERKELEY, Calif.; and KNOXVILLE, Tenn.--Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, is the world’s new No. 1 system with a performance of 33.86 petaflop/s on the Linpack benchmark, according to the 41st edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers. The list was announced June 17 during the opening session of the 2013 International Supercomputing Conference in Leipzig, Germany.

With Roadrunner's Retirement, Petascale Enters Middle Age

Maybe I'm getting old, but the petascale era of supercomputing still feels new to me. On the other hand, the recent decommissioning of IBM's Roadrunner, the world's first petaflopper, suggests otherwise. Roadrunner booted up at the Department of Energy's Los Alamos National Laboratory five years ago in 2008. Its retirement last week marks the approximate mid-point between the first petaflop system and the first exaflop one -- assuming, of course, you're an exascale optimist.

TOP500 Systems and Exascalar Efficiency, Part II (Datacenter Knowledge)

Intel’s Winston Saunders with Part II of his feature piece on how the most recent Top500 and Green500 machines stack up in terms of Exascalar, the “logarithmic distance” to 1018 flops in a 20 MegaWatt power envelope.
