ESnet Leaps Ahead By Two Generations, Upgrades Backbone to 10 Gbps

March 18, 2003

The Energy Sciences Network (ESnet), the high-performance network funded by the U.S. Department of Energy’s Office of Science, has just completed an upgrade to 2.5gigabits (billions of bits or Gbps) per second and 10Gbps in the highest speed portion of the network. Typically, a new generation of data communications bandwidth consists of a fourfold increase in performance. ESnet’s new 10Gbps circuits represent an increase of 16 times existing performance levels, representing a jump of two… Read More »


Lab Quickly Clamps Down on Slammer Worm

January 31, 2003

Some quick thinking by Lab network systems engineer Greg Bell helped protect LBNL, ESnet and other DOE sites from the fast-spreading “SQL Slammer” worm recently. While the Lab had contained the situation within two hours after discovering the attack the evening of Friday, Jan. 24, other organizations weren’t so fortunate. Customers of major banks were unable to use ATMs over the weekend, a major credit card company couldn’t provide users with access to their account information and the… Read More »

Berkeley Lab to Share Expertise in SC2002 Tech Program, Exhibition

November 4, 2002

Lawrence Berkeley National Laboratory, a leader in advancing scientific computing for the U.S. Department of Energy, will share its expertise with the high-performance computing and networking community at the SC2002 conference to be held Nov. 16-22 in Baltimore. Berkeley Lab scientists and users of DOE’s National Energy Research Scientific Computing (NERSC) Center located at the Lab will instruct in three tutorials, give one plenary talk, present 10 technical papers, conduct two… Read More »

Caroline Gatti-Bono Named Second Alvarez Fellow in Computational Science

October 15, 2002

As a computational science fellow at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, Caroline Gatti-Bono's research is reaching new heights. She's currently working to create algorithms for studying how atmospheric effects caused by high mountain ranges, such as the Andes, affect climate on the plains below. Read More »

ESnet Teams with Juniper Networks to Put IPv6 Into Production Alongside IPv4

August 27, 2002

The U.S. Department of Energy’s Energy Sciences Network (ESnet) recently teamed with Juniper Networks became one of the very first networks to run both IPv4 and IPv6 simultaneously on a large-scale production network connecting hundreds of thousands of scientific researchers around the world. The successful rollout of the next generation Internet Protocol, known at IPv6, in parallel with the ongoing use of the current Internet Protocol (version 4, also known as IPv4), is an important step in… Read More »

Berkeley Lab Team Achieves 10.6 Gigabits/second Data Throughput in 10-Gigabit Ethernet Test

July 3, 2002

BERKELEY, CA – Although there has been a lot of discussion recently about 10-Gigabit Ethernet capability, actually achieving that level of performance in the real world has been difficult. Until now. Last week, a team from Lawrence Berkeley National Laboratory, which operates some of the world’s most powerful computing, data storage and networking resources for the U.S. Department of Energy, teamed with Force10 Networks (switches), SysKonnect (network interfaces), FineTec Computers… Read More »


Andreas Adelmann Is NERSC's First Alvarez Fellow in Computational Science

May 29, 2002

While his work in accelerator modeling on supercomputers definitely puts his professional life in the fast lane, Andreas Adelmann and his family are finding it a challenge to adjust to the fast-paced Bay Area lifestyle. Read More »

Lab Team Again Proves Best at Moving Massive Amounts of Data across Networks

November 15, 2001

For the second year in a row, a team led by high-performance computing experts from Berkeley Lab took top honors in a contest to move the most data across the network built around SC, the annual conference of high-performance computing and networking, held last month in Denver. The winning application was a live visualization of a simulation of colliding black holes. SC2001, held this week in Denver, marked the second staging of the Network Bandwidth Challenge in which researchers with… Read More »


RAGE Rolls Out in Denver

November 9, 2001

At the SC2001 supercomputing conference held in Denver, Colorado, November 12-16, visitors are likely to encounter a roaming robot named RAGE. Despite its fearsome moniker, RAGE is intended to be a convivial sort of critter, built specifically for the purpose of extending the reach of the group-communication tool known as the Access Grid to people and events far from the Grid's fixed "nodes."
