  2. Outline • Background • Issues of Interest – UNIX • Issues of Interest – Windows

  3. Background • HEPiX-HEPNT= organization to discuss and share issues specific to HEP computing • Meetings bi-annually • Local reps: • Lisa Giacchetti • Jack Schmidt • Mail list: hepix-hepnt@fnal.gov • Web: http://www.cern.ch/wwwhepix/

  4. Background (cont’d) • Fall ’03 meeting held in Vancouver at TRIUMF (http://www.triumf.ca/) • Web link: http://www.triumf.ca/hepix2003/ • All presentation slides and video of meeting available from “Programme” link • Refer to these for more detail and references/contact info • Meeting Summary available from “Summary” link

  5. *NIX - Trends • Storage/File systems • Many investigating large scale storage solutions and global file system solutions (ala panasas, ibrix, etc…) • CERN setting up “Open Lab” joint venture with commercial entities • IDE raid widely used for bulk data • Tape Technology • STK and 9940b’s widely used • HPSS primary software used to manage

  6. *NIX trends (cont’d) • Monitoring • Ganglia in use at many sites • Nagios is used at a couple of places

  7. New this meeting • Vendor presence • Red Hat presentation on new software distributions • Microsoft presentation on sharing files between Windows and Linux • Panasas talk on Object Oriented storage • IBRIX demo suite

  8. Presentations of interest • Fabric Management Tools at CERN • http://www.triumf.ca/hepix2003/pres/20-17/tkleinwort • Xml based • Node=manageable unit and needs to be autonomous (everything it needs stored locally) • Principles:configuration via one Node install and config reproducible • Success story: LSF upgrade from single tool, config info through one interface and stored centrally. 2.4 to 5.1 on >1000 nodes in 15 minutes, kernel upgrade, security updates • APT for RPM – Simplified Package Management • http://www.triumf.ca/hepix2003/pres/21-03/ftaurino • Alternate to yum. Good comparison of tools

  9. Presentations of interest • PDSF Host Database project • http://www.triumf.ca/hepix2003/pres/21-04/scanon • Similar to miscomp but interface seems more user friendly • Admins use it on a daily basis to track hardware/clusters • Web-based file systems and Webdav • http://www.triumf.ca/hepix2003/pres/21-07/apace • Very interesting cross platform shared file system • Webdav=standardised extension to HTTP protocol using XML for file access via the web • ADC Tests • http://www.triumf.ca/hepix2003/pres/21-14/jiven • Cern’s research activities into new technology • Data challenge process and benchmarks • OpenLab: collaboration with various vendors (hardware contributions from vendors)

  10. Presentations of interest • LCG Talks • LCG-1 Status and deployment http://www.triumf.ca/hepix2003/pres/22-07b/ineilson • LCG Overview and scaling challenges http://www.triumf.ca/hepix2003/pres/22-08/dsmith • Vendor Presentations • Redhat Issues (not taped) http://www.triumf.ca/hepix2003/pres/21-11/dlangley • Windows and UNIX interoperability http://www.triumf.ca/hepix2003/pres/22-11/dfay • Object based storage technology http://www.triumf.ca/hepix2003/pres/22-13/ggibson
