Oak Ridge Leadership Computing Facility

Bart Hammontree sets the stage for Summit supercomputer installation.

To better understand dopamine uptake at neuron synapses, scientists from the Weill Cornell Medical College of Cornell University are using the Titan supercomputer at the Oak Ridge Leadership Computing Facility to simulate important molecular interactions at the neuron membrane.

In June, the OLCF’s Tom Papatheodore led a CUDA workshop to teach students, interns, and researchers how to program on a GPU architecture such as Titan.

The ALCC program provides high-performance computing resources such as America’s fastest supercomputer, Titan, to projects that align with DOE’s energy mission.

OLCF staff members recently participated in coding events that aimed to introduce middle and high school students to computing and coding concepts—CodeStock Academy and WiC’s “Introduce Your Daughter to Code.”

With 2 years left of Titan operation, as well as the recent deployment of new test beds built by Cray, Inc., OLCF is staying active in the Cray community.

A team led by University of Iowa’s George Constantinescu is using Titan to create 3-D non-hydrostatic flood models that can be used to improve the predictive capabilities of existing 2-D models.

Using the 27-petaflop Titan supercomputer, a team of researchers based at Princeton Plasma Physics Laboratory are predicting how ITER—the world’s largest experimental magnetic fusion reactor, which is currently under construction in France—will withstand the extreme heat involved in extracting exhaust.

In response to a growing interest in data services that are integrated with high-performance computing, the National Center for Computational Sciences has expanded its data analysis group, the Advanced Data and Workflow group.

The OLCF played a major role in the annual American Physical Society March Meeting—the largest gathering of physicists in the world—by bringing high-performance computing talks to the meeting as part of a petascale computing focus session.
