Why Science?

Swaroop Pophale

ORNL is proud of its role in fostering the next generation of scientists and engineers. We bring in talented young researchers, team them with accomplished scientists and engineers, and put them to work at the lab’s one-of-a-kind facilities. The result is research that makes us proud and prepares...

Oak Ridge Leadership Computing Facility: Tackling big questions with computation

For some researchers, cracking the big questions can be like mining for a lone diamond under tons of solid rock. In those situations it helps to have a good set of tools, particularly the Oak Ridge Leadership Computing Facility and its Titan supercomputer. Titan isn’t the facility’s first...

ORNL-led study analyses electric grid vulnerabilities

ORNL’s climate and energy scientists have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise. “For the first time, we were able to apply data at a high enough resolution to be relevant,” said ORNL’s Melissa Allen, co-...

Computing by the atom

Computers that grow ever faster require creators who are ever more inventive. The inventors have done well so far, boosting individual processors by fabricating tinier and tinier components, networking hundreds of thousands of processors together, and commandeering specialized devices such as...

Staying ahead of Moore's law: ORNL researchers delve into quantum computing’s quandaries

For all the power and complexity of today’s computers, they can still be boiled down to the binary basics—using a code of 1’s and 0’s to calculate and store information. Since the 1980s, though, some computer scientists have strayed from this simple language. They suggest that computers could speak...

Computers and tanks

The waste tanks at Hanford and Savannah River may not be DOE’s only environmental challenge, but they’re at the top of the list.  Hundreds of tanks hold 90 million gallons of highly radioactive, extremely toxic liquids and sludges. The tanks are in constant flux, although they are nowhere...

Summit will take computing to new heights

There’s a good reason research institutions keep pushing for faster supercomputers: They allow the researchers to develop more realistic simulations than slower machines. This is indispensable for scientists and engineers striving to understand the workings of the universe or to create powerful new...

Titan has a very good year

Summit won’t be open to users for another three years, but let’s not forget that ORNL already has the world’s second-fastest computer—the 27 petaflop Titan. Titan has been ranked either first or second in the world since researchers began using it in 2012. In fact, Titan delivered more computing...
