Department of Energy to Showcase World-Leading Science at SC19

The DOE’s national laboratories will be showcased at SC19 next week in Denver, CO. “Computational scientists from DOE laboratories have been involved in the conference since it began in 1988 and this year’s event is no different. Experts from the 17 national laboratories will be sharing a booth featuring speakers, presentations, demonstrations, discussions, and simulations. DOE booth #925 will also feature a display of high performance computing artifacts from past, present and future systems. Lab experts will also contribute to the SC19 conference program by leading tutorials, presenting technical papers, speaking at workshops, leading birds-of-a-feather discussions, and sharing ideas in panel discussions.”

DOE Extending Quantum Networks for Long Distance Entanglement

Scientists from Brookhaven National Laboratory, Stony Brook University, and DOE’s Energy Sciences Network (ESnet) are collaborating on an experiment that puts U.S. quantum networking research on the international map. Researchers have built a quantum network testbed that connects several buildings on the Brookhaven Lab campus using unique portable quantum entanglement sources and an existing DOE ESnet communications fiber network—a significant step in building a large-scale quantum network that can transmit information over long distances.

SLAC Researchers use ESnet for Record Speed Transfer of 1 Petabyte of Data

“The innovative and versatile nature of ESnet’s OSCARS enabled us to design a unique 5000-mile 100 Gbps loop, which our ESnet colleagues quickly helped establish in 2015,” said Zettar Founder and CEO Chin Fang. “We were thus able to have the data storage clusters and the data transfer nodes co-located in the same rack although they were at both ends of the loop. Physically they were separated by inches, but digitally they are separated by 5000miles. Further the clusters themselves have a self-imposed cap of 80 Gbps.”

Overcoming Roadblocks in Computational Networks

Mariam Kiran is using an early-career research award from DOE’s Office of Science to develop methods combining machine-learning algorithms with parallel computing to optimize such networks. “This type of science and the problems it can address can make a real impact, Kiran says. “That’s what excites me about research – that we can improve or provide solutions to real-world problems.”

Engineering a Better Portal for Scientific Discovery

Engineers from ESnet and the Globus team have designed a new approach that makes data sharing faster, more reliable, and more secure. As described in a new report, the “Science DMZ” provides a new architecture to meet increasing demands for accessing shared data.

Speeding Data Transfer with ESnet’s Petascale DTN Project

Researchers at the DOE are looking to dramatically increase their data transfer capabilities with the Petascale DTN project. “The collaboration, named the Petascale DTN project, also includes the National Center for Supercomputing Applications (NCSA) at the University of Illinois in Urbana-Champaign, a leading center funded by the National Science Foundation (NSF). Together, the collaboration aims to achieve regular disk-to-disk, end-to-end transfer rates of one petabyte per week between major facilities, which translates to achievable throughput rates of about 15 Gbps on real world science data sets.”

How Zettar Transferred 1 Petabyte of Data in Just 34 Hours Using AIC Servers

In the world of HPC, moving data is a sin. That may be changing. “Just a few weeks ago, AIC announced the successful completion of a landmark, 1-petabyte transfer of data in 34 hours, during a recent test by Zettar that relied on the company’s SB122A-PH, 1U 10-bay NVMe storage server. The milestone was reached using a unique 5000-mile 100Gbps loop which is a SDN layer over a shared, production 100G network operated by the US DOE’s ESNet.”

SLAC & Berkeley Researchers Prepare for Exascale

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory are playing key roles in two recently funded computing projects with the goal of developing cutting-edge scientific applications for future exascale supercomputers that can perform at least a billion billion computing operations per second – 50 to 100 times more than the most powerful supercomputers in the world today.

Software Defined Networking to Speed Data for Cori Supercomputer

NERSC is working with Cray to explore new ways to more efficiently move data in and out of Cori, a powerful supercomputer being constructed in California. “We need to take advantage of a network guru’s design for moving data for a specific experiment but have SDN do all of the bookkeeping for which compute nodes need to be connected to what networks,” said Brent Draney, group lead for the Networking, Servers and Security Group at NERSC. “I would rather see our network engineers analyze the data flow and how to meet the need instead of having to manually reconfigure the network for the demands of each job.”

NSF Sponsors Women Engineers for SCinet Buildout at SC16

The Networking at SC (WINS) program officially launched today. Funded through a grant from the NSF and ESnet, the program sponsors eight career women in the research and education network community to participate in the build out and live operation of SCinet. “Not only is WINS providing hands-on engineering training to the participants but also the opportunity to present their experiences with the broader networking community throughout the year.”
