The world's first fastest supercomputer is Cray XT5, also known as “Jaguar”. Located at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) for achieving another supercomputing milestone. With a peak speed of 2.33 petaflops (over two thousand trillion calculations per second),
The new 1.64-petaflop Cray XT Jaguar features more than 180,000 processing cores, each with 2 gigabytes of local memory. The resources of the ORNL computing complex provide scientists with a total performance of 2.5 petaflops. Which beating IBM's Roadrunner, who has been holding the top crown since past 18 months.

Roadrunner is a supercomputer built by IBM at the Los Alamos National Laboratory in New Mexico, USA.
Currently the world's second fastest computer. The supercomputer was designed and developed for the DOE and Los Alamos National Laboratory (LANL) under the DOE/LANL project name "Roadrunner."
In November 2008, it reached a top performance of 1.456 petaflops, retaining its top spot in the TOP500 list.
3.
Cray XT5 system, also known as "Kraken" was ranked as world's 3rd fastest supercomputer. Located at the National Institute for Computational Sciences (University of Tennessee), Kraken supercomputer achieved a speed of 832 teraflop/s. A teraflop/s is a trillion calculions per second. Both Kraken and Jaguar are Cray XT5 supercomputers.
4.
IBM's BlueGene/P was ranked as world's 4th fastest supercomputer. Located at the Forschungszentrum Juelich in Germany. The BlueGene/P is the fastest computer outside United States. It achieved 825.5 teraflop/s.
5.
Tianhe-1 supercomputer, and was ranked as world's 5th fastest supercomputer. Tianhe-1, which means River in Sky, is located at the National Super Computer Center in Tianjin, China. The system is used for research in petroleum exploration and simulation of large aircraft designs.
Tianhe-1 achieved a speed of 563 teraflops in the tests, but it is capable of 1.042 petaflops, and is a hybrid design with Intel Xeon and AMD graphics processors used as accelerators. Each node consists of two AMD GPUs attached to two Intel Xeon chips. Tianhe-1 runs an operating system based on the Linux kernel.
6.
SGI Altix supercomputer known as Pleiades, was ranked as world's 6th fastest supercomputer. The supercomputer is located at NASA's Ames Research Center (NAS).
7.
The seventh fastest supercomputer in the world is again from IBM, BlueGene/L. The supercomputer is located at Lawrence Livermore National Laboratory's Terascale Simulation Facility. After an upgrade in 2007 the performance increased to 478.2 trillion floating operations per second (teraFLOPS) on Linpack.
BlueGene/L had been used widely for materials science calculations such as assessing materials at extreme temperatures and pressures.
8.
IBM BlueGene/P was ranked as world's 8th fastest supercomputer. The supercomputer was installed in 2007 in US-based Argonne National Laboratory.
9.
Sun Microsystem's Ranger was ranked as world's 9th fastest supercomputer. 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
10.
Juropa was ranked as world's 10th fastest supercomputer. Companies from Europe and the United States have joined hands with Forschungszentrum Jlich research centre in Germany, to enter the future of high-performance cluster computing.
The system was designed by experts of the Jülich Supercomputing Center and implemented in conjunction with partner companies Bull, Sun, Intel, Mellanox and ParTec. Es besteht aus 2208 Rechenknoten mit einer Gesamtrechenleistung von 207 Teraflop/s. It consists of 2208 compute nodes with a total computing performance of 207 teraflop / s.
