The OLCF’s new ARM1 early development system gives researchers the opportunity to test various software packages and explore an experimental environment for ARM architecture–based systems.
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.
In 2016, the OLCF introduced a new runtime framework that allows users of hybrid systems—such as the OLCF’s 27-petaflop Titan—to better exploit GPU-accelerated architectures.
OLCF staff created the Constellation DOI framework that makes it possible for a researcher to obtain a digital object identifier (DOI) to catalog and publish scientific data artifacts for open access.
OLCF staff members led a workshop January 10–12 to provide CAAR teams with a quickstart guide for using the Summitdev early access system, which features IBM’s POWER processors and NVIDIA’s Pascal GPU–based architecture.
Leveraging the high-performance computing and data resources provided by the OLCF and CADES, neuroscience researchers are advancing the computational modeling of individual neurons.
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.
Open Scalable File Systems, Inc. (OpenSFS), the nonprofit community organization dedicated to Lustre file system technology, recently changed its structure to give users a premier role in the organization. File and Storage System Team Lead Sarp Oral will represent the OLCF on the newly appointed OpenSFS board.
ORNL recently partnered with Oracle to test some of the database technology company’s new firmware in a collaborative laboratory environment inside the OLCF’s High-Performance Storage System. Oracle is providing five of its enterprise-class tape drives, while ORNL is providing the resources, networking, and manpower for the testing environment.
