teraFLOPS

(tera FLoating point OPerations per Second) One trillion floating point operations per second. IBM's BlueGene/L supercomputer, designed for computational science at Lawrence Livermore National Laboratory, was upgraded in 2007 from 65,536 to 106,496 processing nodes, where each added node had twice the memory of the old. The result for BlueGene/L: a peak speed of 596 teraFLOPS.

Human TeraFLOPS
It has been said that the human brain processes 100 teraFLOPS; however, the older one gets, that seems to be a gross exaggeration!

The fourth largest super on the list, nicknamed Tungsten, is installed at the National Center for Supercomputing Applications (NCSA), is comprised of two-way Dell Corp PowerEdge 1750 servers with a total of 2,500 3.06 GHz Pentium 4 Xeon DP processors from Intel and rated at 9.8 teraflops.
The current goliath of supercomputing is Earth Simulator, built by NEC Corp for the Japanese government, which is rated at 40 teraflops. Earth Simulator is a parallel cluster of vector processors that run at 500MHz.
So going from approximately 4 Teraflops to 24 Teraflops is bound to need a lot of power right?
Combined, both systems will achieve a total theoretical peak performance of 691.7 teraflops, making the new supercomputer system the largest-scale system in the Kyushu region of Japan.
On a per processor basis, Big Ben is 2.4 times faster than LeMieux, which has 3,000 processors and provides six teraflops of peak performance.
IBM's long-term goal is to demonstrate a TRIPS chip by 2010 that can jam 1 teraflops of computing power into a single chip.
The first system--called ASCI Purple-will offer the Department of Energy the world's first supercomputer capable of up to 100 teraflops, more than twice as fast as the most powerful computer in existence today.
At present, India's fastest supercomputer is housed at CSIR Center for Mathematical Modelling and Computer Simulation in Bengaluru, delivering a top performance of 303.9 teraflops. Telecom and IT minister, Kapil Sibal has supposedly written to Prime Minister Manmohan Singh, detailing a Rs.
system registered maximum performance of 190.9 teraflops (one teraflop is one trillion floating point operations per second).
Each node features two Intel Xeon X5650 processors, allowing for a total of 600 CPUs and a theoretical peak performance of 38.3 teraflops. The interconnect that manages inter-node communications is equipped with an InfiniBand QDR network interface, which enables data to be transferred at 4GB/s, while allowing for high-speed parallel calculations.
