What is the performance of super computer?

Answer 1

The fastest supercomputer today\u0026#39;s fastest supercomputer is the Roadrunner. This monster cost $ 120 million and weighing 250 tons in 2008, ranks first in the TOP500, the list of most powerful supercomputers in the world. List is regularly updated University of Mannheim and Tennessee, The most important criterion for getting into the TOP500 is computing power, measured in FLOPS (Floating point operations per second, the translation from English. - The number of computational floating-point operations per second). Developed by IBM Roadrunner supercomputer delivers 1,105 PFLOPS (1 PFLOPS \u003d 10 to 15 degrees FLOPS). That is, this \u0026quot;hog numbers\u0026quot; can do more quadrillion operations per second. For comparison: if all the inhabitants of the Earth (about 6 billion) have calculators and performed one operation per second, Roadrunner still would have worked quickly to 180 thousand times. Compared with today\u0026#39;s desktop PC (the performance of about 40 GFLOPS), this supercomputer is considered fast in the 27 500 times. Like most supercomputers, Roadrunner in the U.S.. Fourth place in the TOP500 list is based on the German system of IBM BlueGene / P, a 12 place - domestic supercomputer \u0026quot;Lomonosov\u0026quot;, established at Moscow State University (his actual performance is 350, and the peak - to 415 TFLOPS). How are supercomputers Unlike most home PC with one processor, one hard disk and two to four memory modules, today\u0026#39;s supercomputers represent a union of thousands of individual spetskompyuterov, called nodes, each of which typically includes multiple processors. For this purpose, standard high-performance processors, usually Intel Xeon or AMD Opteron. Individual nodes are connected with each other in a very fast network that gives you great overall performance. Such a structure called a parallel computer, the most important task is the distribution of computational tasks on multiple processors to multiple speed increases. Supercomputers are a major manufacturer of Hewlett-Packard and IBM, which together have built nearly 400 of the 500 fastest supercomputers in the world. Significant contribution is also the company Cray and SGI, have created a very powerful supercomputers, although not in such numbers. Programme for Supercomputing For supercomputers require special software. Software is as important for fast and reliable operation, as well as equipment. Normal Windows on that computer would work no faster than a simple PC, since it could use a few of the many thousands of processors. Therefore, supercomputers typically use specific operating systems, such as Scientific Linux.
