ESnet Staff Featured in Podcast About Network Performance

Nobody owns the Internet. It’s essentially a global collection of networks, both big and small. These networks connect in many different ways to form the single entity that we know as the Internet. When everything moves as it should, it’s easy to marvel at how seamlessly these networks work together. But when there is a problem, it’s really hard for engineers to pinpoint the source. This is where perfSONAR comes in. In this podcast from Packet Pushers, ESnet’s Brian Tierney and Nick Buraglio (who will officially join ESnet Oct. 7) discuss how this open-source package of networking tools pinpoints and solve problems that may span multiple networks and international boundaries. ESnet led the international collaboration that developed perfSONAR. The tool is currently deployed in over 100 locations around the world. Read More.

Bringing Energy Efficiency to HPC

The ability of high performance computers (HPCs) to solve complex applications has risen exponentially since their introduction in the 1960s—along with their electricity use. Many HPCs require more than a megawatt of electricity to operate, and annual electricity costs can run into millions of dollars. As the use of HPCs became more widespread, Berkeley Lab researchers saw the need to improve their energy efficiency. Thus, a grassroots collaboration—the Energy Efficient High Performance Working Group—was born. The group, which includes Computational Research Division’s (CRD's) John Shalf and Erich Strohmaier, aimed to promote energy-efficient computing best practices and to drive improvements in energy performance of HPC systems. Learn how their efforts have paid off.  Read More

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
