OAK RIDGE, Tenn. (WVLT) -- The Oak Ridge National Laboratory is once again home to the world's most powerful computer, according to a semiannual ranking of computers from around the world, the Top500.
"We'll deliver science from Day One with Titan, and I look forward to the advancements the Titan team will make in areas such as materials research, nuclear energy, combustion and climate science," said ORNL Director Thom Mason.
Titan, which replaced the XT5 Jaguar, reclaimed the crown held by its predecessor from November 2009 through June 2010, said the Dept. of Energy. The supercomputer is reportedly capable of a theoretical peak speed of 27 quadrillion calculations per second - 27 petaflops - while using approximately 9 megawatts of electricity, roughly the amount required for 9,000 homes.
"The new Top500 list clearly demonstrates the U.S. commitment to applying high-performance computing to breakthrough science, and that's our focus at Oak Ridge," said Mason.
According to numbers provided by ORNL, Titan reached a speed of 17.59 petaflops on the Linpack benchmark test - the specific application that is used to rank supercomputers on the Top500 list. It is Titan 10 times faster than Jaguar with only a 20 percent increase in electrical power consumption.
