Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

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.

        Experiences with SpamCop 30m
        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.

        Service Level Status - A Real-time status Display for IT 30m
        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.

        Using RT to Manage Installation Workflow 30m
        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.

        Using Quattor to manage a grid (EGEE) Fabric 30m
        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.

        RACF's PXE Installation Management System 30m
        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.

        Support of Kerberos 5 Authenticated Environment by TORQUE 30m
        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.

        Planning for Hall D: The Hazards of Fast Tape Drives 30m
        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.

        Storage Class : Problematic and Implementation at CCIN2P3 30m
        Storage Classes attempt to represent storage use cases for a given experiment. It is considered harmfull to match the storage classes to real life storage system especialy if the latter is based on path to get the storage configuration of a file. This presentation aims to define the problematic of Storage Classes, explain one possible solution which is implemented at CCIN2P3 and discuss the pros ans cons.

        The Stakkato Intrusions 45m
        During 15 months, from late 2003 until early 2005, hundreds of supercomputing sites, universities and companies worldwide were hit by a series of intrusions, with the perpetrator leapfrogging from site to site using stolen ssh passwords. These are collectively known as the Stakkato intrusions, and includethe Teragrid Incident and the Cisco IOS source code theft, both of which received widespread attention from the media. This talk will cover case studies of performed intrusions, an analysis of why Stakkato could be so successful, and the story of how the suspect was finally tracked down and caught.

        Network Security Monitoring with Sguil 30m
        Most mid- or large-sized organizations conduct some sort of network monitoring for security purposes. Traditional Intrusion Detection Systems (IDS) tell only part of the story, leaving analysts to perform complex and time-consuming data-mining operations from multiple sources just to answer simple questions about IDS alerts. This talk presents a more efficient model that uses the open source Sguil software to optimize the process for analyst time and efficiency.

        GridX1: A Canadian Computational grid for HEP Applications 30m
        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.
