TOP500 is a list of the 500 fastest computer systems and their characteristics. The list is sorted by the Rmax value of each computer using the high-performance LINPACK benchmark and thus provides a ranking of the most powerful machines for solving linear systems of equations dar. From June 2008, the energy consumption is listed.


Originating from the TOP500 Hans -Werner Meuers is 1986-1992 published annually Mannheim supercomputing statistics. It only installed in the U.S., Japan and Europe vector computer systems were counted. The figures were based this on information from the manufacturer. The difficult data situation, especially in Japan, the increasing popularity of massively parallel systems, and high-performance computers generally did a reorganization necessary.

To make the list of better and more verifiable basis, then took over the organization TOP500, which is represented by the Universities Mannheim and Tennessee and the National Energy Research Scientific Computing Center, the compilation of the list. The commitment to 500 entries took place because on the one hand the last Mannheim Supercomputer list had 530 entries, on the other hand, with respect to the Forbes 500 list of the most successful companies. Since June 1993, the TOP500 is worked out twice a year and presented alternately taking place in Germany International Supercomputer Conference and taking place in the U.S. Supercomputer Conference.

Listed computer


The fastest computer in the world (as of June 2013):


The three fastest supercomputers are German (June 2013):


The three fastest computers are Swiss (June 2013):


The Austrian fastest supercomputer is the VSC -2 with 20,776 Opteron cores lying with 152.9 TFLOPS at number 238 (as of June 2013). The VSC -2 is the second stage of the Vienna Scientific Cluster, a joint project of the Technical University of Vienna, Vienna University and the University of Agricultural Sciences, Vienna. The first stage, the VSC-1, is still in operation, but with 53.07 TFLOPS no longer among the TOP500.

Operating Systems

The Top 8 of the current supercomputer (June 2012) operate under a Linux derivative. A total of the TOP500 systems

  • 462 ( ie 92.4 %) under Linux,
  • 24 under Unix,
  • 2 on Windows (seats 94 and 156)
  • 1 BSD ( ranked 145 ) and
  • 11 mixed operated.

In the " mixed " as specified systems are exclusively for Blue Gene systems under CNK / SLES 9, ie the minimal compute node kernel and SUSE Linux 9
