In the “Star Trek” episode “The Ultimate Computer,” the Starship Enterprise tests a fully automated command and control platform that can—hypothetically—do everything the crew does, only faster and without the inevitable human error. Not surprisingly, things go awry and the computer goes rogue, f...

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 worl...
