OAK RIDGE, Tenn., Aug. 30 (UPI) -- A U.S. government supercomputer's power has been increased to 54 teraflops -- 54 trillion mathematical calculations per second.

The computer, dubbed Jaguar, is an upgrade of the Cray XT3 supercomputer at Oak Ridge National Laboratory and is among the most powerful open scientific systems in the world, officials said.

Laboratory officials said Jaguar -- the largest in the Department of Energy's Office of Science -- is available to all scientific researchers and research organizations, including industry, through an annual call for proposals.

Michael Strayer, director of the Department of Energy's Office of Advanced Scientific Computing Research, said "The expanded system will be instrumental in addressing some of the most challenging scientific problems in areas such as climate modeling, materials science, fusion energy and combustion."

The upgrade involved replacing all 5,212 processors with Cray's latest dual-core processors, doubling the supercomputer's memory and bisection bandwidth. The Jaguar features more than 10,400 processing cores and 21 terabytes of memory.

Laboratory officials said the supercomputer is expected to exceed 100 teraflops by the end of this year and to reach a petaflop, or 1 quadrillion mathematical calculations per second, by 2009.
