Fastest Computer
Only the name has changed. IBM has maintained the manufacturers of the fastest computers in the world. Instead of the perennial winner of the Blue Gene / L, this time is Roadrunner based on U.S. Energy Department, Los Alamos National Laboratory. This IBM supercomputer reached a petaflop speeds, first ever by any team.
The ranking was announced today at the International Supercomputing Conference in Dresden, Germany, event biennial which ranks the 500 most powerful computers in the world. According to the Top500 rankings, reaching a maximum yield of 1026 petaFLOPS (floating point operations per second) to take first place. A petaflop equals one billion, or one thousand trillion calculations per second. The No. 2 Blue Gene / L, also made by IBM at Lawrence Livermore National Laboratory, achieved a speed of 478.2 teraflops.
IBM Roadrunner is powered by 12,240 IBM PowerXCell 8i chips cell similar to those found in console games. The basic functions are performed by computing AMD Opteron 6562 dual heart, leaving the Cell chips for the solution of all work necessary for the mathematical calculus intensive in which the specialized processors. You need the space of 278 refrigerator-racks of servers in size.
IBM maintaining its dominant position in supercomputing, makes 210 of the 500 supercomputers. 5 of the 10 supercomputers is IBM. Just behind them is HP (Hewlett-Packard), which 183 fastest computers.
The top 10 fastest supercomputers
Take a look
- The fastest supercomputer in the world is also one of the most efficient energy.
- The No. 1, 2, 3 and 5 are in U.S. laboratories Department of Energy.
- United States remains the center of supercomputers in the world with more than half the systems (257) located in the United States
- United States followed by the United Kingdom with 53, Germany with 46, France 34, Japan with 22 and China with 12. More than half of the systems used quad-core processors.
- Most systems (208 of 500) contain between 2049 and 4096 processors. It is more than double the amount that systems using only six months ago.
- Intel dominates the market for high-end processors with 75 percent of all systems on the list and 90 per cent of quad-core based systems that have been classified.
