Sreenivas Rangan Sukumar, former group leader of the OLCF's Advanced Data and Workflow group, spearheaded the ORiGAMI project. The software is now open-source, and is up for an R&D 100 Award. Staff members involved in high-performance computing at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) stand…
A team at the Oak Ridge Leadership Computing Facility recently addressed a performance bottleneck in one portion of an OLCF user’s application. Because of its efforts, the user’s team saw a sixfold performance improvement in the code.
OLCF Staff members recently upgraded the OLCF’s data transfer service. The team included (front row, left to right) Sergey Shpanskiy, Jason Anderson, and Dustin Leverman; (back row, left to right) Jason Kincl, Jason Hill, and Clay England; (not pictured) Daniel Pelfrey, Jesse Hanley, and Lawrence Sorrillo. Data transfer can be…
Researchers at US Department of Energy (DOE) national laboratories frequently transfer files between experimental and observational facilities, their home institutions, and computational facilities like the Oak Ridge Leadership Computing Facility (OLCF), a DOE Office of Science User Facility located at DOE’s Oak Ridge National Laboratory (ORNL). Moving large files between…
The Deep Learning Users Group, organized by the OLCF’s Advanced Data and Workflow Group, gathered this summer to discuss topics related to deep learning, a fast-growing offshoot of machine learning with potential for automating knowledge discovery. Though they sprout from the same family tree, scientific computing and artificial intelligence (AI)…
Researchers from commercial and industrial property insurer FM Global want to improve fire protection standards across the country. The company, which insures one in three Fortune 1000 companies with a unique focus on helping clients prevent losses, is dedicated to understanding how fires spread and, conversely, how they can be…
The OLCF’s Advanced Data and Workflow Group and the Computer Science and Mathematics Division’s Scientific Data Group have worked together to scale R—the most commonly used data analytics software in academia and a rising programming language in high-performance computing—to the OLCF’s Rhea, Eos, and Titan systems. With big science comes…
ORNL recently hosted the Eclipse User Group and Development Meeting to teach best practices for using Eclipse’s community of open-source software solutions.
OLCF staff delivered talks and tutorials to Lustre users covering the center’s on-going contributions to the effort to expand the parallel file system’s performance and flexibility.
ORNL's MDF recently reached out to the Oak Ridge Leadership Computing Facility’s (OLCF’s) Advanced Data and Workflow Group for assistance with 3-D visualization.
Forge, a combination of the Allinea DDT and MAP software tools, will continue to provide users at the OLCF with the debugging capability of DDT while adding the MAP software.
The OLCF will support a new service, Spark On-Demand, that enables users to instantiate Apache Spark to conduct in situ data analysis on OLCF compute resources.
Optimizing compute jobs based on these separate and combined streams of information, however, can be challenging. Fortunately for staff and users at the OLCF, a new tool called the Grand Unified Information Directory for the OLCF (GUIDO) has been developed to enhance existing capabilities.
