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.
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.
OLCF scientific computing liaison Gustav Jansen received honorable mention for the 2017 Hermann Kümmel Early Achievement Award in Many-Body Physics. The award recognizes “young physicists whose published work is a significant contribution to quantum many-body theory.”
The Titan supercomputer at the Oak Ridge Leadership Computing Facility has enabled scientists from a team led by Lawrence Berkeley National Laboratory to explore an unexpected oxidation state in the rare, radioactive element berkelium that was first observed in experiment.
Oak Ridge Leadership Computing Facility staff discussed OLCF resources that could be leveraged for ECP research and development, including the facility’s next flagship supercomputer, Summit, expected to go online in 2018.
While upgrading chemistry applications in the pre-Summit development environment known as Summitdev, Oak Ridge Leadership Computing Facility staff fixed an unexpected bottleneck in a key tensor algebra library, boosting performance by as much as 10 times.
Using the Titan supercomputer, researchers from Oak Ridge National Laboratory (ORNL) and the Oak Ridge Leadership Computing Facility (OLCF) collaborated with the University of California, Los Angeles (UCLA), Lawrence Berkeley National Laboratory (Berkeley Lab), and other institutions to simulate—for the first time—atomic-level magnetic properties in regions of a real nanoparticle based on experimental data. The results have been published in Nature.
A new version of OpenACC—an application programming interface that integrates accelerators with a host CPU—is due for release in mid-2017. In 2016, OLCF user assistance staff participated in the annual OpenACC standards organization meeting that resulted in a list of features for the new version.
The Oak Ridge Leadership Computing Facility and General Electric, an industry user of the OLCF’s 27-petaflop Titan supercomputer, have been recognized in the annual HPCwire Readers’ Choice Awards for Best Use of HPC Application in the Energy Industry.
