IEEE Quotes LBNL Staff in Announcing New Ethernet Standard

On October 5, IEEE announced the ratification of the IEEE P802.3az Energy-Efficient Ethernet (EEE) standard, the first standard in the history of Ethernet to address proactive reduction in energy consumption for networked devices. Michael Bennett of Berkeley Lab’s IT Division is chair of the IEEE 802.3az Energy-Efficient Ethernet Task Force.

The IEEE press release quotes Bennett as saying, in part, “The great advantage of using products supporting EEE is that there is no complex configuration necessary. In most cases, energy will be saved automatically.” The press release also includes quotations from Berkeley Lab CIO Rosio Alvarez and ESnet manager Steve Cotter.

Registration Closes Tomorrow for NERSC User Group Meeting

Registration closes tomorrow (Tuesday, October 12) for next week’s NERSC User Group Meeting at OSF or by remote attendance. Training sessions will be held Monday through Wednesday, October 18–20, with the business meeting on Thursday, October 21. See the draft agenda.

Hopper Phase 2 Power-Up Celebration This Wednesday

The celebration of the full configuration and power-up of NERSC’s Hopper Phase 2 system has been rescheduled to 4:00–5:00 pm Wednesday, October 13, in OSF Room 238. Cray will provide three cases of Leinenkugel beer (brewed in Chippewa Falls, Wisconsin, birthplace of Seymour Cray and home to one of Cray’s R&D facilities). There will be non-alcoholic drinks as well, and folks are invited to bring salty or sweet snacks.

Mellander and Lant to Discuss Bro at Network Security Summit

Jim Mellander and Craig Lant of NERSC are giving several presentations on LBNL’s intrusion detection system, Bro, at the Network Security Monitoring Technical Summit being held this week, October 11–14, at Pacific Northwest National Laboratory in Richland, Washington. The NSM Summit presents opportunities for cyber-security specialists from many DOE national laboratories to share leading-edge technical solutions with their colleagues. NERSC is teaming with the IT division’s Anne Hutton to present a comprehensive view of Bro’s capabilities as a high speed IDS, especially relevant in light of ever-increasing bandwidth requirements.

This Week’s Computing Sciences Seminars

OSF Brown Bag: Co-Array Fortran Programming with Application to the GTS Code
Tuesday, October 12, noon, OSF Room 238
Robert Preissl, NERSC Petascale Postdoc

Robert is working Stephane Ethier at PPPL and others to implement one-sided communication in the GTS code using Co-Array Fortran. He will discuss his work and share his experiences using the Hopper II test system, Grace.

High Performance Computing: Union of Software and Reconfigurable Logic
Tuesday, October 12, 6:30 pm networking and food, 7:00 pm presentation
Microsoft Research, 1288 Pear Ave., Mountain View (free, registration required)
Ivo Bolsens, Senior VP and CTO, Xilinx

Modern FPGA platforms have capabilities that are well suited to assume a more central role in the implementation of complex embedded processing systems. In particular, FPGAs are well placed to be at the heart of complex signal processing, packet processing and high performance computing applications because of their high computational efficiency matched by high bandwidth concurrent memory access and rich on-chip interconnectivity, all of this combined with complete programmability.

The key to unleashing the full horsepower of FPGA platforms to the system designer is, first of all, a hardware platform that allows tight integration between the processor, the programmable logic and the memory. Second, the hardware architecture has to be supported by a programming flow that abstracts the hardware implementation details and provides seamless and efficient mapping of system functions on multiple processor cores and programmable hardware functions. Finally, a programmable infrastructure has to be provided that targets specific requirements for packet processing or signal processing or high performance computing.

Molecular Engineering to Computer Science: The Role of Photonics in the Marriage of Computing and Communications
Friday, October 15, 11:00 am–12:30 pm, 521 Cory Hall (Hogan Room), UC Berkeley
Robert F. Leheny, Assistant Director, Information Science and Technology Division, Institute for Defense Analyses

This presentation will discuss the remarkable advances in photonic materials science and engineering (molecular engineering) technologies that have paralleled, and in many respects have enabled, the development, over the last fifty years, of today’s networked information technologies; and provide some insights into the current status of research supporting the continued advancement in support of IT technologies.

Link of the Week: Scholars Test Web Alternative to Peer Review

Traditional peer review has shaped the way new research has been screened for quality and then how it is communicated; it has defined the border between the public and an exclusive group of specialized experts. Today a small vanguard of digitally adept scholars is rethinking how knowledge is understood and judged by inviting online readers to comment on works in progress; and one journal, Shakespeare Quarterly, is using crowd sourcing as an adjunct to peer review. Read more in “Scholars Test Web Alternative to Peer Review” by Patricia Cohen in the New York Times.

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 6,000 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 DOE 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.
