A supercomputer is a computer that is at the frontline of current processing capacity, particularly speed of calculation. Supercomputers were introduced in the 1960s and were designed primarily by Seymour Cray at Control Data Corporation (CDC), and led the market into the 1970s until Cray left to form his own company, Cray Research. He then took over the supercomputer market with his new designs, holding the top spot in supercomputing for five years (1985–1990). In the 1980s a large number of smaller competitors entered the market, in parallel to the creation of the minicomputer market a decade earlier, but many of these disappeared in the mid-1990s "supercomputer market crash".

There's a new numero uno in the World's fastest supercomputers ranking, reveals the bi-annual Top500 list. The Top500 supercomputers list is compiled by researchers at the University of Mannheim (Germany), Berkeley National Laboratory (US) and the University of Tennessee (US).
Just as in the last time's ranking, the Top500 list is made up mostly of Hewlett-Packard and IBM computers. HP accounted for 210 of this year's 500, and IBM 185. In terms of processors, Intel still enjoys the lion's share, with 80 percent. The most popular operating system continues to be Linux, with 90 percent share.
Here's over to the world's top 10 fastest supercomputers.

1. Jaguar

The world's fastest supercomputer is Cray XT5, also known as Jaguar. Jaguar bags the no. 1 spot, beating IBM's Roadrunner, who has been holding the top crown since past 18 months.
Jaguar recently upgraded its quad-core CPUs to hex-core Opteron processors, which meant a 2.3 petaflop per second theoretical performance peak (”nearly a quarter of a million cores”), and 1.75 petaflops measured by the Linpack benchmark. This surpasses Roadrunner's 1.04 petaflop/s. A petaflop/s refers to 1 quadrillion calculations per second.
Jaguar, located at the US Department of Energy's Oak Ridge Leadership Computing Facility, came close to beating Roadrunner in the two previous Top500 lists. This time, however, Roadrunner's performance fell from 1.105 petaflop/s in June due to a repartitioning of the system.

2. Ranger

At no. 9 is Sun Microsystem's Ranger. The Ranger supercomputer belongs to Sun's Blade System family. The supercomputer is located at Texas Advanced Computing Center. Running on AMD x86_64 Opteron Quad Core 2300 MHz processor, Rangers main memory is a mammoth 125952 GB
