Earthquake Drill Scheduled for Wednesday, June 6

The Lab’s annual earthquake drill will be held Wednesday, June 6, as part of Emergency Preparedness Week at LBNL. The drill will begin at 10 a.m. Wednesday with instructions over the public address system telling everyone to assume there has just been an earthquake. Offsite buildings will simulate the PA announcement via the communications at their locations. After dropping, covering and holding, employees will be told by members of Building Emergency Teams to evacuate their buildings. The “all clear” will be provided to the building managers via the building emergency radios. The entire drill should take about 15-20 minutes.

ESnet Workshop to Focus on Future Network Requirement for Basic Energy Sceinces

ESnet is hosting a workshop today and tomorrow (June 4-5) “to accurately characterize the networking requirements of science funded by DOE’s Basic Energy Sciences (BES) Program Office. These requirements will serve as input to the ESnet architecture and planning processes, and will help ensure that ESnet continues to provide world-class support for scientific discovery for DOE scientists and their collaborators. The tangible outcome of the workshop will be a document that includes both the network requirements and a supporting narrative,” according to the workshop Web site. The by-invitation-only workshop is being held in Gaithersburg, Md.

SciDAC 2007 Tutorials Workshop to Provide Hands-On Intro to Petascale Tools

To provide computational scientists with hands-on training in topics related to petascale computing, the SciDAC (Scientific Discovery through Advanced Computing) Outreach Center and the Massachusetts Institute of Technology are cosponsoring a daylong tutorials workshop on Friday, June 29, at MIT.

The workshop, which will include 10 tutorial sessions, is being held in conjunction with the June 24-28 SciDAC 2007 Conference in Boston. The SciDAC Tutorials Workshop is open to all physical scientists, mathematicians, computer scientists, and computational scientists. There is no workshop fee, but registration in advance is required, and in the event of oversubscription, space in the tutorials will be allocated according to the order of registration. More information, including a link to the registration page, can be found at: http://www.scidac.gov/Conference2007/tutorials/index.html.

Since its inception in 2001, collaborative SciDAC research teams of physical scientists, mathematicians, computer scientists, and computational scientists have developed a wealth of software and computational tools for scientific petascale computing. Members of these research teams will lead the tutorials to familiarize participants with the use of key SciDAC software and computational tools. Here is a list of the scheduled sessions:

* Interoperable Technologies for Advanced Petascale Simulations (ITAPS) Tools for Geometry, Mesh, and Field Manipulation, presented by Lori Diachin (Lawrence Livermore National Laboratory), Mark Shephard (Rensselaer Polytechnic Institute) and Tim Tautges (Argonne National Laboratory)
* Parallel I/O in Practice, presented by Rob Ross and Rob Latham (Argonne National Laboratory)
* Enabling Distributed Petascale Science, presented by Ian Foster and Jennifer Schopf (Argonne National Laboratory and the University of Chicago)
* Data Parallel Software for Lattice QCD, presented by James Osborn (Boston University) and Andrew Pochinsky (MIT)
* Introducing VORPAL, presented by John Cary (TechX Corp)
* High-Resolution and Adaptive Numerical Methods and Software for Partial Differential Equations, presented by Phil Colella, Brian van Straalen, and Dan Martin (Lawrence Berkeley National Laboratory)
* Load-balancing and partitioning for scientific computing using Zoltan, presented by Erik Boman and Karen Devine (Sandia National Laboratories)
* Scalable Solvers for PDE-based and other simulations, presented by Rob Falgout (Lawrence Livermore National Laboratory), Mike Heroux (Sandia National Laboratories) and David Keyes (Columbia University)
* Scientific Data Understanding: Using the VisIt and SCIRun Visualization and Analysis Tools, presented by Sean Ahern (Oak Ridge National Laboratory) and Allen Sanderson (University of Utah)
* Component Software for High-Performance Computing: Using the Common Component Architecture, presented by Rob Armstrong (Sandia National Laboratories), David E. Bernholdt and James A. Kohl (Oak Ridge National Laboratory) and Gary Kumfert (Lawrence Livermore National Laboratory)

Descriptions of the tutorials can be found at http://www.scidac.gov/Conference2007/tutorials/tutorials.html.

The SciDAC Tutorials Workshop is sponsored by the MIT Laboratory for Nuclear Science, the CyberInfrastructure Engineering Lab in the Harvard School of Engineering & Applied Sciences, the Center for Computational Science at Boston University and the SciDAC Outreach Center.

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.
