Connectors in the Titan supercomputer at Oak Ridge National Laboratory have been repaired, and workers are preparing the world’s fastest machine for a second round of acceptance testing, an official said Monday.

That testing could allow the $100 million machine to be put into full production mode by the end of this month or early May, said Jeff Nichols, ORNL associate lab director for computing and computational sciences.

Titan won’t be available to researchers for a short period while the lab re-runs acceptance tests. [Read more…]

Hundreds of connectors are being re-soldered each week, and the Titan supercomputer at Oak Ridge National Laboratory—the world’s fastest machine—could be in regular production by May, a lab official said Wednesday.

Jeff Nichols, ORNL associate lab director for computing and computational sciences, said connectors on the $100 million computer’s motherboards had too much gold, and solder was interacting with the gold on connector pins, making the solder unstable and leading to cracks.

There are about 20,000 of the pencil-sized connectors, which link central and graphic processing units, or CPUs and GPUs. Each connector has about 100 pins.

Oak Ridge National Laboratory regained the lead in high-performance computing, enjoyed record-setting recognition for its research, and became a showpiece for renewable energy technology during 2012.

The U.S. Department of Energy’s Office of Science reciprocated with favorable marks in its annual appraisal of managing contractor UT-Battelle. DOE cited the laboratory’s operation of its scientific user facilities, its “delivery of impactful science,” and a successful workforce restructuring to reduce operating costs.

“The dedicated efforts of our laboratory staff in all phases of science and technology and operational support have resulted in an excellent record of delivering science to the nation in 2012,” said ORNL Director Thom Mason. “ORNL will continue to set the pace in research toward a clean and secure energy future.”

ORNL’s 2012 included achievements in both research and support.

Not only is Oak Ridge National Laboratory’s Titan the world’s most powerful supercomputer, it is also one of the most energy-efficient.

Titan came in at number three on the Green500 list. Organized by Virginia Tech’s Wu-chun Feng and Kirk Cameron, the list takes the world’s 500 most powerful supercomputers—as ranked by the Top500 list announced Monday—and reorders them according to how many calculations they can get per watt of electricity.

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.”

The new Titan supercomputer at Oak Ridge National Laboratory is now the world’s fastest, according to a Top 500 list released this morning.

A Cray XK7 system, Titan achieved 17.59 petaflops on a benchmark test, equal to more than 17,000 trillion calculations each second, a press release said.

Titan knocked Lawrence Livermore National Laboratory’s Sequoia from the No. 1 spot and into second place. Sequoia is an IBM BlueGene/Q system, and it was No. 1 in June with 16.32 petaflops.

The Oak Ridge National Laboratory launched a new era of scientific supercomputing today with Titan, a system capable of churning through more than 20,000 trillion calculations each second—or 20 petaflops—by employing a family of processors called graphic processing units first created for computer gaming. Titan will be 10 times more powerful than ORNL’s last world-leading system, Jaguar, while overcoming power and space limitations inherent in the previous generation of high-performance computers.

Titan, which is supported by the U.S. Department of Energy, will provide unprecedented computing power for research in energy, climate change, efficient engines, materials, and other disciplines, and pave the way for a wide range of achievements in science and technology.
