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.
