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

High performance computing plays a critical role in scientific discovery, and researchers increasingly rely on advances in computer science, mathematics, computational science, data science, and large-scale computing and networking to increase our understanding of ourselves, our planet, and our universe. Berkeley Lab’s Computing Sciences Area researches, develops, and deploys new foundations, tools, and technologies to meet these needs and to advance research across a broad range of scientific disciplines.

Founded in 1931 on the belief that the biggest scientific challenges are best addressed by teams, Lawrence Berkeley National Laboratory and its scientists have been recognized with 13 Nobel Prizes. Today, Berkeley Lab researchers develop sustainable energy and environmental solutions, create useful new materials, advance the frontiers of computing, and probe the mysteries of life, matter, and the universe. Scientists from around the world rely on the Lab’s facilities for their own discovery science. Berkeley Lab is a multiprogram national laboratory, managed by the University of California for the U.S. Department of Energy’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 energy.gov/science.
