Cray XT5 Supercomputer at Oak Ridge National Laboratory Named World's Fastest Supercomputer

By DE Editors

The Cray XT5 supercomputer, nicknamed “Jaguar,” located at the Department of Energy’s Oak Ridge National Laboratory (ORNL) has been recognized by the Top 500 list as the world’s fastest supercomputer.

“We are pleased that the upgraded Cray XT5 system at ORNL has added this new honor to its growing list of achievements,” said Peter Ungaro, president and CEO of Cray. “While we are thrilled to have designed and built a supercomputing system that has broken a number of firsts in the industry, we are most proud of the fact that Jaguar is used day-in and day-out to solve real-world scientific problems at sustained speeds that no other system in the world can match—including the first two scientific applications in the world ever to break one petaflops in sustained performance.”

In 2008, Jaguar became the first high performance computing system to set a new world record for computer speed with sustained performance of over one petaflops (quadrillion mathematical calculations per second) on two scientific applications.  This fall, the Jaguar system was upgraded with Six-Core AMD Opteron processors, increasing the number of its processing cores to more than 224,000 and advancing its peak performance to more than two petaflops of compute power.
