Oak Ridge Leadership Computing Facility

Researchers simulating high-temperature superconductors has topped 15 petaflops on ORNL’s Titan supercomputer. More importantly, they did it with an algorithm that substantially overcomes two major roadblocks to realistic superconductor modeling.

Scientists from Germany’s HZDR–Dresden used Titan, the most powerful supercomputer in the United States located at Oak Ridge National Laboratory, to simulate billions of particles in two passing plasma jet streams.

A simulation of the internal workings of cells has reached a sustained performance of 20,000 trillion calculations per second, or 20 petaflops, on the Titan supercomputer at ORNL.

Researchers are using DOE’s most powerful computing systems, including the nation’s top-ranked machine, ORNL’s Titan, to simulate the evolution of the universe as it expands across billions of years.

Four out of six Association for Computing Machinery’s Gordon Bell Prize finalists used Titan to overcome complex computational challenges in their fields.

Researchers from Purdue University, the University of Alabama–Huntsville, and Switzerland’s ETH Zurich are finalists for this year’s coveted ACM Gordon Bell Prize, thanks to a nanoscale simulation of electronic devices performed on Oak Ridge National Laboratory’s Jaguar supercomputer.
