Tracing its roots back to the days of dial-up modems in the 1970s, ESnet has consistently worked to make the network faster and more robust. Typically this has been done by taking advantage of new data transfer technologies and upgraded hardware. But with the emergence of software-defined networking over the past decade, ESnet is pioneering new possibilities for automatable networking in real time. More>
Representatives from the Lab’s five national user facilities attended the Society for Science at User Research Facilities (SSURF) Annual Meeting in late June. JGI Director Nigel Mouncey presented, “How Facilities Can Partner With Industry to Strengthen the Scientific Infrastructure.” The Molecular Foundry’s Alison Hatt, who also serves on the SSURF Board of Directors, moderated a session.

The three-year, $3.5 million grant the National Science Foundation awarded to Indiana University and the Lab’s Energy Sciences Network (ESnet) will create EPOC, the Engagement and Performance Operations Center, which will allow researchers to routinely, reliably, and robustly transfer data through a holistic approach to understanding the full pipeline of data movement — and better supporting collaborative science.

The Senate Energy and Natural Resources Committee hosted a User Science Exhibition last month. The Society for the Science at User Research Facilities (SSURF) — which includes the Lab’s Molecular Foundry, NERSC, Joint Genome Institute, ESnet, and the Advanced Light Source — hosted exhibits and demos of their research and conveyed the positive impact of user facilities.
With all the ways the web is used today, it was created 30 years ago primarily to help access and share scientific data. The web remains central to researchers today, but the most common method of sharing data remains firmly attached to its earliest days. This can be a huge obstacle to scientific discovery. A new approach to address this issue has been developed. More>
Eli Dart (ESnet), Michael Wehner (CRD), and Prabhat (NERSC) recently teamed up to document the data transfer workflow, data transfer performance, and other aspects of moving approximately 56 terabytes of climate data from the distributed Coupled Model Intercomparison Project (CMIP5) archive to NERSC.

Like other complex systems, computer networks can break down and suffer bottlenecks. Keeping systems running smoothly requires algorithms that can identify problems and find solutions on the fly. Mariam Kiran is using her DOE Early-Career Research Program award to develop methods combining machine-learning algorithms with parallel computing to optimize such networks. More>
A new Petascale Data Transfer Node (DTN) project — spearheaded by ESnet — aims to achieve regular disk-to-disk, end-to-end transfer rates of one petabyte per week between major supercomputing facilities. This translates to achievable throughput rates of about 15 GB per second on real world science data sets. More>
Like other sciences, medical research is generating increasingly large datasets that need to be shared. However, the data that could help stop the spread of deadly viruses or create precision medical treatments require high levels of security and individual privacy, safeguards that a Science DMZ could meet, researchers recently proposed.

The Nobel Prize in Physics was awarded to scientists in the LIGO Scientific Collaboration who discovered gravitational waves. Software tools developed by researchers in the Lab’s Computational Research Division played a key role in enabling the analysis of the vast quantities of data generated by LIGO.
