Agenda as of Thursday, 11-0ct-01 15:07:06. The final agenda differs from this draft. See also the report of the meeting from Alan Silverman Monday: UNIX Issues Tuesday: UNIX Issues and Site Reports Wednesday: Common Issues and Windows Issues Thursday: Windows Issues Monday Oct 15 UNIX Issues 9:00 Future Directions in Scientific SuperComputing (Horst Simon - NERSC Director) 9:30 Benchmarking CDF Code (Rochelle Lauer - Yale University Physics Department) This brief talk describes benchmarks performed at the Compaq Greenbelt Maryland Benchmark Facility. The goal was determine which Intel based multi-processor running Redhat Linux 6.1 would provide adequate performance for compiling, linking and running CDF code at Yale. The factors which led to the requirement for a benchmark as well as the benchmark requirements are discussed. Benchmark results are presented 10:00 Break 10:30 Linux Filesystems Part II (Steven Chan - NERSC) 11:00 A General Purpose High Performance Linux Installation Infrastructure (Alf Wachsmann - SLAC) I shall talk about SLAC's Linux Installation Infrastructure. It is a fully automatic infrastructure which uses PXE as network boot component on the nodes. It uses DHCP and TFTP server to get IP addresses and a bootloader to all nodes. It then uses Kickstart to install Red Hat Linux over NFS. To make everything unattended and automatic, I have written some short scripts to glue these services together. In particular, I have a script for automatic and reliable MAC addresses detection. I shall show some benchmark results from a recent cluster installation. They show among other intersting things the overall installation time of about 30 Minutes for all 256 machines. 11:30 Lunch (This will be at the lab cafeteria.) 13:00 Large Scale Distributed Computing (Nick Cardo - NERSC) 13:30 Installing and running Sun Grid Engine (Friebel, Wolfgang - CERN) I will present the batch system concept for the DESY Zeuthen Linux farm, which is based on the SGEEE (Sun Grid Engine Enterprise Edition) software. I will discuss the benefits from using this open source software and from changing our queue policies. 14:00 Experiences of Batch Utilization at CERN (CHARBONNIER Catherine - CERN) The latest steps in the batch system evolution at CERN have been to reduce the multitude of clusters and to focus on improving the sharing of the resources amongst user communities. We will present the current status, experience with different configurations we have tried out and how we plan to evolve the configurations to cope with LHC demands. 14:30 FBS (Farm Batch System) status report (Tanya Levshina - Fermilab) FBS overview and new features implemented since November, 2000 (HEPiX-HEPNT, Jefferson Lab) 15:00 Break 15:30 DataGrid Testbed Status (Michel Jouvin - LAL / CNRS) DataGrid prepares the second phase of its testbed. It will be the first release of components developed by Datagrid Working Packages, to enhance basic functionalities provided by Globus framework. This presentation will give an overview of features that will be introduced, problems met so far and plans for the near future. 16:00 Grid Engine batch queuing and resource management software (Shannon Davidson - Raytheon) 1 Hour The focus of the presentation will be on how Grid Engine works and the capabilities that it provides. 17:00 End of day Tuesday Oct 16 UNIX Issues/ Site reports 8:00 Registration 9:00 NERSC Storage talk (Nancy Meyer - NERSC) HPSS@NERSC : current stats short sum of changes(net,disk,tape) repack @ media conversion managing hpss: ops support + golden rules 9:30 Computer Security Update (Bob Cowles - SLAC) Exploits and vulnerabilities since the last conference will be discussed. Some things to look forward to based on presentations at the Defcon conference last July. 10:00 Break 10:30 How to improve network transfers (Shane Canon - NERSC) 11:30 Lunch 1:00 Site reports Lisa Giacchetti FERMILAB Rochelle Lauer Yale University Physics Department Alan Silverman CERN Sandy Philpott Jefferson Lab Jouvin Michel LAL/IN2P3 Corrie Kost TRIUMF Wojcik CCIN2P3 Roberto Gomezel INFN Chuck Boeheim SLAC Thomas Yanuklis RHIC Computing Facility Shane Canon NERSC David Kelsey RAL Henner Bartels DESY Henner Bartels (Windows Site Report) DESY 15:00 Break Wednesday Oct 17 Common Issues and Wmdows Issues 9:00 lt's all kerberos, right? Microsoft and Unix Kerberos Interoperability (Chris Brew - Fermilab) 9:30 NGOP Status Report (Tanya Levshina - FERMILAB) current state of deployment and future development 10:00 Break 10:30 FERMI PC Vendor Qualification Update (Lisa Giacchetti - FERMILAB) This talk will be on our most recent PC vendor qualification procedures and how the first purchases based on this qualification went. 11:00 A Summary of the Large Cluster Computing Workshop in Fermilab in May 2001 (Alan Silverman - CERN) 11:30 Lunch 13:00 NERSC Security Practices (Steve Lau - NERSC) 1 hour NERSC is unique in supercomputing centers in that we believe in an open system. This presents a unique challenge in protecting our systems from unauthorized and malicious use. I will be giving an overview of NERSC's computer security methods, our recent experiences, future plans and how users of NERSC can help in ensuring their computational experiences are secure ones. 14:00 Towards efficient storage-over-IP solutions (John Goebel - SLAC for CASPUR) Our experience with a new hardware that allows for new ways of storage access for commodity farms will be described. This middleware may also be used for asymmetric guaranteed SCSI delivery over WAN. 14:30 LAL recent move from SCSI based storage to Fiber Channel SAN (Michel Jouvin - LAL) 15:00 Break 15:30 Software Certification (Alan Silverman - CERN) A scheme to publicise and perhaps share information about the software certification in the major HEP sites. 16:00 Windows NT and Windows 2000 File Permissions Incompatibilities (Andrea Chan - SLAC) 16:30 Exchange and Email Anti-Virus at SLAC (Teresa Downey - SLAC) The SLAC conversion to Exchange and changes in email anti-virus methods will be discussed. We'll also bring you up to date on our current configuration and lessons learned over the past two years. 17:00 End of day Thursday Oct 18 Windows Issues 9:00 The Fermilab Windows 2000 Domain Structure (Tim Doody - Fermilab) 10:00 Break 10:30 Tuning your network quasi hands on (Brent Draney - NERSC) 1 hour 11:30 Lunch (This might be open if we end at noon.) 13:00 Tour of Advanced Light Source (ALS) and the lab facility.
