Weathering the Flood of Big Data in Climate Research
ESnet's Eli Dart moved 56 TB of climate data from 21 sites to NERSC, a task that took three months. In contrast , it took just two days to transfer the raw dataset using Globus from NERSC to the Mira supercomputer at Argonne National Laboratory.

Confirmed: Stellar Behemoth Self-Destructs in Type IIb Supernova
For the first time, astronomers have direct confirmation that a Wolf-Rayet star died in a violent explosion known as a Type IIb supernova. Using the iPTF pipeline, researchers caught supernova SN 2013cu within hours of its explosion. These observations are providing valuable insights into the life and death of the progenitor Wolf-Rayet. These stars are interesting because they enrich galaxies with the heavy chemical elements that eventually become the building blocks for planets and life. Read More
ESnet’s Mike Bennett Retiring after 26 Years of Making Key Connections
Since he started working at the lab back in 1988, Mike Bennett has found himself in the middle of a number of interesting transitions. But come April 30, he’ll make his last one – transitioning into retirement. When Bennett started as an engineering technologist at the Bevatron, one end of the control room was filled with analog equipment featuring knobs, dials, oscilloscopes and other… Read More
100 Gbps Test Link Sets Pace for Faster Trans-Atlantic Data Transfers
Data transfers from the Large Hadron Collider at CERN in Switzerland to sites in the U.S. have historically taken different paths – 15 in all – via 10 gigabit per second (Gbps) links separately managed by three research networks in the U.S. and Europe. So what would happen if those massive datasets were instead transferred using a single 100 Gbps connection? That was the thinking behind an… Read More
ESnet Staff to Present at Internet2's 2014 Global Summit
About 800 networking experts from across the country and around the world are meeting April 6-11in Denver for Internet2’s annual “Global Summit,” a weeklong series of presentations, discussions and meetings aimed at improving the performance of research and education networks. The name of the conference, formerly the Internet2 Members Meeting, was chosen to reflect the increasingly… Read More
Democratizing Science With High Speed Networks
For the first time, data collected and analyzed by a very remote user of National Center for Electron Microcopy (NCEM) via the Energy Sciences Network (ESnet) has been published. As a result, many scientists are optimistic about the future of remote microscopy for DOE supported science. Read More
Deployments of Network Monitoring Software perfSONAR Hit 1,000
In January 2014, perfSONAR reached a milestone with 1,000 instances of the diagnostic software installed on networking hosts around the U.S. and in 13 other countries. perfSONAR is a joint effort between the ESnet, Fermilab and SLAC; and Georgia Tech, Indiana University, Internet2 and the University of Delaware.
