Titan, once the world’s fastest computer, will be retired Aug. 1

The Titan supercomputer at Oak Ridge National Laboratory debuted as the fastest computer in the world in 2012, and it remained in the top 10 for seven years, providing billions of core hours of total computing time to researchers from around the world. The system will be decommissioned on Aug. 1, 2019, and its data center space will be retrofitted for a new supercomputer, Frontier. (Photo by ORNL)

A supercomputer that was once the world’s fastest will be retired at Oak Ridge National Laboratory on August 1.

The supercomputer is a Cray XK7 machine called Titan. It is operated by the Oak Ridge Leadership Computing Facility. It’s a petaflop system capable of performing up to 27 quadrillion calculations per second.

Titan was the world’s fastest supercomputer in November 2012, but it was bumped to number two by Tianhe-2, a Chinese supercomputer in June 2013. Still, Titan continued to rank as one of the world’s top 10 fastest supercomputers from its debut at number one in 2012 until this June, when it dropped to number 12.

In June, ORNL said Titan, which has been operating for seven years, will be decommissioned on August 1 and disassembled for recycling. Titan will be removed to make room for a new, much more powerful supercomputer, Frontier. That will be an exascale system capable of 1.5 exaflops, or 1.5 quintillion calculations per second (a billion billion calculations per second). Frontier will be a $600 million Cray computer that is expected to be the world’s most powerful when it debuts in 2021.

Miaofang Chi of the Center for Nanophase Materials Sciences at Oak Ridge National Laboratory has earned the ORNL Director’s Award for Outstanding Individual Accomplishment in Science and Technology.

ORNL Director Thom Mason presented the award to Chi on Friday during the annual Awards Night event in Knoxville hosted by UT-Battelle, the management and operating contractor for ORNL.

Chi was honored for her pioneering early career research in analytical electron microscopy. Chi’s research has advanced the understanding of defect and interface chemistry and structure and how such defects control materials properties at the atomic level. Her work includes the recent development of transformative insitu microscopy methods to probe transport phenomena at the atomic scale.

Chi also earned the Early-Career Researcher Award. [Read more…]

Buddy Bland, project director of the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory, will discuss world-leading computing and ORNL sciences during a lunchtime meeting Tuesday.

The meeting on Tuesday, September 8, is open to the public.

“Today, the Titan supercomputer at ORNL is one of the world’s fastest and most productive tools for science at every scale,” a press release said. “From the composition of nucleons from quarks, to nanomaterials, to chemistry and biology, to transportation, to fission and fusion reactors, to astrophysics, modeling, and simulation using high-performance computers has transformed the way we do science and engineering. This presentation will cover a brief history of computing at ORNL, where we are going in the future, and the impact that computing has on our local community, the nation, and the world.” [Read more…]

Oak Ridge National Laboratory’s Titan supercomputer has completed rigorous acceptance testing to ensure the functionality, performance, and stability of the machine, one of the world’s most powerful supercomputing systems for open science.

The U.S. Department of Energy machine, the first to combine different types of processing units to maximize performance at such a large scale, ranked as the fastest supercomputer in the world in the November 2012 list published at http://www.top500.org/. Titan, a Cray XK7 supercomputer, is capable of more than 27,000 trillion calculations each second—or 27 petaflops. [Read more…]

World’s fastest supercomputer at ORNL more about research than rankings

The No. 1 ranking for the new Titan supercomputer, designating it as the most powerful in the world, was clearly appreciated in East Tennessee on Monday.

But even as they celebrated a return to the top spot, scientists at Oak Ridge National Laboratory, where the giant computer is based, said they are focused more on research than rankings.

“We love being No. 1,” said Bronson Messer, acting group leader for scientific computing at the National Center for Computational Science at ORNL. “It’s great recognition. But what really matters is what science will do with the machine.”
