The TOP500 project ranks and details the 500 (non-distributed) most powerful known computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, the second one is presented in November at the ACM/IEEE Supercomputing Conference. The project aims to provide a reliable basis for tracking and detecting trends in high-performance computing and bases rankings on HPL, a portable implementation of the High-Performance LINPACK benchmarkwritten in Fortran for distributed-memory computers.

The TOP500 list is compiled by Hans Meuer of the University of Mannheim, Germany, Jack Dongarra of the University of Tennessee, Knoxville, and Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory.

Project history

In the early 1990s, a new definition of supercomputer was needed to produce meaningful statistics. After experimenting with metrics based on processor count in 1992, the idea was born at the University of Mannheim to use a detailed listing of installed systems as the basis. Early 1993 Jack Dongarra was persuaded to join the project with his Linpack benchmark. A first test version was produced in May 1993, partially based on data available on the Internet, including the following sources:

• "List of the World's Most Powerful Computing Sites
  
  
  " maintained by Gunter Ahrendt


• David Kahaner, who had an immense amount of data.

The information from those sources was used for the first two lists. Since June 1993 the TOP500 is produced bi-annually based on site and vendor submissions only.

Since 1993, performance of the #1 ranked position steadily grew in agreement with Moore's law, doubling roughly every 14 months. The fastest system as of November 2010 is roughly 36,000 times faster (in terms of peak Tflops) than the fastest system as of June 1993.

Legend

• Rank – Position within the TOP500 ranking. In the TOP500 List table, the computers are ordered first by their Rmax value. In the case of equal performances (Rmax value) for different computers, the order is by Rpeak. For sites that have the same computer, the order is by memory size and then alphabetically.


• Rmax – The highest score measured using the LINPACK benchmark suite. This is the number that is used to rank the computers. Measured in quadrillions of floating point operations per second, i.e. petaflops.


• Rpeak – This is the theoretical peak performance of the system. Measured in Pflops.


• Name – Some supercomputers are unique, at least on its location, and are therefore christened by its owner.


• Computer – The computing platform as it is marketed.


• Processor cores – The number of active processor cores actively used running Linpack. After this figure is the processor architecture of the cores named. If the interconnect between computing nodes is of interest, it's also included here.


• Vendor – The manufacturer of the platform and hardware.


• Site – The name of the facility operating the supercomputer.


• Country – The country in which the computer is situated.


• Year – The year of installation/last major update.


• Operating System – The operating system that the computer uses.

Japan’s “K Computer” maintained its position atop the newest edition of the TOP500 List of the world’s most powerful supercomputers, thanks to a full build-out that makes it four times as powerful as its nearest competitor. Installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, the K Computer it achieved an impressive 10.51 Petaflop/s on the Linpack benchmark using 705,024 SPARC64 processing cores.

The K Computer is the first supercomputer to achieve a performance level of 10 Petaflop/s, or 10 quadrillion calculations per second. In June 2011, the partially built K computer had taken the No. 1 position with a performance of 8.16 Petaflop/s. Contrary to many other recent very large systems, it does not utilize graphics processors or other accelerators. The K Computer is also one of the most energy efficient systems on the list.

Still in second place is the Chinese Tianhe-1A system with 2.57 Petaflop/s performance. One year ago, the Tianhe-1A system took the top spot, but was dethroned when the next TOP500 list was published six months ago.

In fact, the Top 10 supercomputers on the latest list – the 38th edition of the twice-yearly list – remain unchanged from June 2011. The latest list, the data behind it and the trends it reflects will be the topic of a Birds-of-a-Feather session to be held at 5:30 p.m. Tuesday, Nov. 15, at the SC11 supercomputing conference in Seattle.

“This is the first time since we began publishing the list back in 1993 that the top 10 systems showed no turnover,” said TOP500 editor Erich Strohmaier, who will lead the discussion at SC11.

The largest U.S. system is a Cray XT5 system called Jaguar and installed at the Oak Ridge National Laboratory, with a 1.75 Petaflop/s performance running the standard Linpack benchmark application. Other top U.S. systems include Cielo, a Cray XE6 at Los Alamos National Laboratory (No. 6); Pleiades, an SGI Altix machine at NASA’s Ames Research Center (No.7); Hopper, a Cray XE6 at the National Energy Research Scientific Computing Center (No. 8); and Roadrunner, an IBM system that was the first ever to break the Petaflop/s barrier, at Los Alamos (No. 10). Systems in China, Japan and France round out the Top 10.
