Oak Ridge National Laboratory on 29th Oct2012 made operational the worlds fastest Supercomputer ---the Titan supercomputer is a Cray machine made of nearly 19,000 processing units stitched together with 710 terabytes of memory.
Claiming the first place it made 'Sequoia' second-most-powerful supercomputer with a crunching performance of 20 petaFLOPS.
i.e this machine can perform 20 thousand trillion calculations per second.
The Cray Titan is expected to be number 1 on the TOP500 list November 2012 update in a supercomputing conference in Salt Lake City.
Titan is 10 times as powerful as Oak Ridge National Lab’s last big supercomputer, called Jaguar. Most of the internals on Jaguar were used in Titan to reduce the costs.
Titan uses the same building and 200 cabinets covering 404 sqm (4352 sq ft) that Jaguar did, simply replacing the internals.Reusing the power and cooling systems already in place for Jaguar saved the lab approximately US $20 million.This machine cost $100 million. Its electric bill will total $9 million a year. These numbers are huge,but worth of maintaining this machine are great. Here are some ---
