Description
The HEPiX forum unifies IT system support engineers from the High Energy Physics (HEP) laboratories and institutes, such as BNL, CERN, DESY, FNAL, IN2P3, INFN, JLAB, NIKHEF, RAL, SLAC, TRIUMF and others. The HEPiX meetings have been held regularly since 1991, and are an excellent source of information for IT specialists. That's why they enjoy large participation also from the non-HEP organizations.

        Spamcop is a popular tool on the internet for reporting
        "spammers" to the ISP's. Several HEP sites have signed up
        SpamCop as a method of detecting spam. Unfortunately, the
        way Fermilab processes bounced spam email it can appear to
        Spamcop that Fermilab is an initiator of spam. This has
        occurred several times in the past year. To resolve the last
        incident, we requested several sites add Fermilab to their
        servers whitelists. In addition, we adjusted our mail
        gateways to eliminate bounced spam messages whenever
        possible. We are also looking into improving our spam
        filtering systems to minimize any spam that might get
        through and subsequently forwarded to another site. We would
        like to discuss getting together a list of other HEP sites
        and their email servers, and sharing this list so that we
        don't inadvertantly block each others email transmissions.

      • 11:30 Service Level Status - A Real-time status Display for IT 30'
        Nowadays, IT departments provide, and people use many
        various computing services of more and more heterogeneous
        nature. And there is a growing need of having a common
        display that groups these different services and reports
        about their status and availabilities in a uniform way. At
        CERN, it led to launching the SLS project.
        
        Service Level Status Overview (SLS) is a web-based tool that
        dynamically shows availability, basic information and
        statistics about various IT services, as well as
        dependencies between them.
        
        The presentation starts with a short description of the
        project, its goals, architecture, and users. Then, the
        concepts of subservices, metaservices, dependencies, service
        availability etc. are introduced, followed by a
        demonstration of the system and an explanation of how to add
        a service to SLS. The talk ends with a information on how
        SLS could be used by other HEP institutes.

      • 14:00 Using RT to Manage Installation Workflow 30'
        We had a need to more formally manage the workflow of
        installation tasks, because there had gotten to be so many
        happening simultaneously that confusion was resulting.  We
        modeled the workflow using RT, the Request Tracking system
        that we use for user requests.  The result is a relatively
        lightweight and flexible system that gives planners a
        "dashboard" of the status of all active projects, and the
        information they need to execute the task.

        Deploying grid services means managing a potentially large
        number of machines that partially share their configuration.
        A tool is needed not only to install but to maintain such a
        configuration. Quattor, developped as part of EDG, is such a
        tool. This talk will focus on the LCG/gLite support in Quattor.

        The BNL RHIC/ATLAS Computing Facility (RACF)  Central
        Analysis/Reconstruction Server (CAS/CRS) Farm is a large
        scale computing cluster currently consisting of ~2000
        multiprocessor
        hosts running Scientific Linux.  Besides providing for
        computation, the CAS/CRS systems' local disk drives are used
        by network 
        distributed data systems such as dCache, ROOTD and XROOTD to
        store considerable amounts of data (presently ~400 TB).  The
        sheer number of systems in the farm, combined with our
        distributed storage model complicates network installation
        management.  
        This presentation describes the system developed at RACF to
        fully automate and simplify management of the PXE
        installation process.

      • 09:30 Support of Kerberos 5 Authenticated Environment by TORQUE 30'
        TORQUE is a successor of the OpenPBS batch queuing system,
        available as an Open Source product. Despite the wide spread
        usage of TORQUE as Job Management System on  computational
        farms and LHC grid installations, this batch system does not
        support any advanced authentication mechanisms. 
        We show two possibilities, how to redesign the existing
        source code in order to add Kerberos 5 authentication
        support for batch jobs. 
        The first way uses local server-client RPC connections while
        the second one makes use of the Authenticated Remote Control
        tool (ARCv2).
        The described modifications have been successfully deployed
        in the local computing infrastructure of the H1
        Collaboration at DESY. This provides on identical
        environment for batch jobs and
        user desktop processes.

        The upgrade to Jefferson Lab will require a hardware refresh
        of the mass storage system in order to handle the higher
        volume of data from new experiments and simulations. The
        next generation, higher capactity tape drives are also
        significantly faster, a fact that has implications for
        almost all parts of the mass storage system. This talk
        examines the performance tuning required to make efficient
        use of these drives and underscores some of the particular
        needs of tape-based storage systems used by most experiments.

        Incident and the Cisco IOS source code theft, both of 
        which received widespread attention from the media.

        time-consuming data-mining operations from multiple sources
        just to answer simple questions about IDS alerts.  This talk

        GridX1 is a Canadian computational grid which combines the
        shared resources of several Canadian research institutes for
        the primary purpose of executing HEP applications. With more
        than two years of production experience, GridX1 has
        demonstrated the successful application of Globus Toolkit
        (GT) v.2 cluster gatekeepers managed by a Condor-G resource
        brokering system. A novel feature of the project was a
        resource brokering interface to the LHC Compute Grid, which
        was used during Data Challenge 2 to route ATLAS jobs to the
        Canadian resources without having dedicated Compute Elements
        at each cluster. Further, independent Condor-G resource
        brokers have been implemented to manage the Canadian ATLAS
        and BaBar MC production systems. Finally, our recent efforts
        have been directed toward building a service-oriented grid
        using GT4, including a WS-MDS registry service and WS-GRAM
        enabled metaschedulers built upon Condor and GridWay.
