June 18, 2008 - the 31st of the global top 500 super computers TOP500 formally announced, this means that the global list of high-performance computing formally entered a new region - with 1 petaflop / s (more than 1000000000000000 floating-point Operational / second) supercomputer.

The list of champions for IBM for the U.S. Department of Energy Los Alamos National Laboratory built called "Roadrunner" computer system, the faster it reached 1.026 petaflop / s (1000000000000000 / second), it is also the first Taiwan more than one 1000000000000000 / second super computer system at the same time, the system or the TOP500 list of the highest energy consumption efficiency of the system.

The system uses the IBM Q22 blade construction, the use of processors based on the POWER architecture of the processor, since it goes beyond the November 2004, has held the top spot from IBM for the DOE's Lawrence Livermore National Laboratory built BlueGene / L system. Now, this computing power to 478.2 teraflop / s (trillion / sec) of the Blue Gene ranked No. 2.

List of the top five supercomputers are located in the United States, 3, 4, 5-were in the United States Argonne National Laboratory's IBM BlueGene / P system (450.3 teraflop / s) (trillion / sec), located in Texas Advanced Computing Center Sun SunBlade x6420 "Rover" system (326 teraflop / s) (trillion / sec), and in the United States Oak Ridge National Laboratory's Cray XT4 "Jaguar" system (205 teraflop / s) (trillion / S).

No. 6 called in the U.S. territory of the strongest super-computing power of computer systems, located in Germany Forschungszentrum Juelich (FZJ), based on the IBM BlueGene / P systems, computing power for the 180 teraflop / s (trillion / sec).

The processor type, according to statistics, in the list of all systems, Intel processor market share continued to increase, from last November, which released the list of the 70.8 percent increase to the current 75 percent. In addition, four core processors by the wider use of high-performance computing capabilities to enhance the important reasons, the list, 56 percent of the system uses four core processors.

From geographical perspective, the United States ranked first with 257 units, followed by 53 sets of the United Kingdom, Germany 46 sets, 34 sets of France, 22 sets of Japan, mainland China and Taiwan a total of 15 sets.

In the field of operating systems, Linux operating system continue to maintain a leading position with 427 sets of super computer system to use the Linux operating system, use the Unix operating system sets the number at 25, Windows operating system for five sets.
