  1. HEPNTan update David KelseyCLRC Rutherford Appleton Lab, UKd.p.kelsey@ rl.ac.ukhttp://hepwww.rl.ac.uk/HEPNT/ D.P.Kelsey - HEPNT update - HEPiX/RAL

  2. Outline • Reminder - What is HEPNT? • HEPNT meetings (since HEPiX/FNAL) • Sep 98 (#6) • Dec 98 (Open meeting - #7) • Jan 99 (#8) • Future plans D.P.Kelsey - HEPNT update - HEPiX/RAL

  3. What is HEPNT? (1) • Sub-group of HTASC • Set up by HEP-CCC in May, 1997 • Mandate for 12 months, then extended to 2 years • Deliberately different from HEPiX • Small closed group of active NT people • Inform others via the WWW • http://hepwww.rl.ac.uk/HEPNT/ • also via the Open meeting (Dec 98) • Collaboration with HEPiX is important • must not polarize the community (UNIX vs NT)! D.P.Kelsey - HEPNT update - HEPiX/RAL

  4. Members of HEPNT • K. Bos NIKHEF • A. Chan+others SLAC • D. Foster CERN • J. Gordon RAL • D. Kelsey RAL (Chairman) • A.Pace CERN • J. Schmidt FNAL • G.P. Siroli Univ Bologna+INFN • J. Surget Saclay • G. Trowitzsch DESY - Zeuthen D.P.Kelsey - HEPNT update - HEPiX/RAL

  5. What is HEPNT? (2) • ‘Information Exchange’ not a ‘Solution Provider’ • no extensive investigations or development • Where necessary (and possible?), • coordinate NT activities • enable interworking between sites • enable interworking NT/UNIX (with HEPiX) • We do not intend to standardise the desktop • We do not recommend (or impose!) single solutions on HEP except where necessary • e.g. compilers D.P.Kelsey - HEPNT update - HEPiX/RAL

  6. HEPNT meetings • 7 (closed) meetings have been held discussing ... • NT installation and configuration • System management • NT farms • CERNLIB, LHC++ on NT, Compilers • WAN file access/sharing • UNIX/NT integration • NT V5.0 • Security • Software licensing • Experiences with NT in HEP experiments • Use of NT for development of Webs D.P.Kelsey - HEPNT update - HEPiX/RAL

  7. Meeting #6 (CERN) 24/25 Sep 98 • NT Internet Services on NICE (Alberto Di Meglio, CERN) • demand for interactive web services growing, including forms, scripts, access to databases • showed architecture for personal webs for NICE/NT • http://cname.web.cern.ch/dirname • Use MS FrontPage 98 as authoring tool • CERN have also tested scalability of NTFS file servers • conclude - can support up to 1000 users/server D.P.Kelsey - HEPNT update - HEPiX/RAL

  8. Meeting #6 (2) • AFS on Windows NT study (R. Toebbicke, CERN) • AFS client for NT - similar to UNIX client • Good for WAN file sharing (NT/UNIX, or NT/NT) • Can AFS be used as an NT home file system? • Impact of NTFS specifics (ACLs, Client/Server both accessing the file, e.g. FrontPage 98) • Few problems encountered • HEPNT conclusions ... • AFS not recommended as sole home file system • best interim solution for WAN file sharing • use NTFS for NT profiles D.P.Kelsey - HEPNT update - HEPiX/RAL

  9. ‘HEPNT Days’ at CERN 2-4 Dec 98 • Open meeting (#7) - aimed at NT system managers • 67 participants from 11 countries • The important themes… • Installation, configuration and management • CERN, DESY, FNAL, SLAC - all different! • how to scale down in size - cloning seems best • Windows 2000 (NT5) • Very important issues and opportunities! • We should try to agree on an AD design and look at possibilities for HEP • An HEP migration group seems desirable D.P.Kelsey - HEPNT update - HEPiX/RAL

  10. HEPNT Days (2) #7 • Security • Important! • Must share experiences • UNIX/NT integration • UNIX and NT are both here to stay • NT is just another operating system • We should use each for the appropriate tasks • Make it easy for physicists to use which they want D.P.Kelsey - HEPNT update - HEPiX/RAL

  11. HEPNT Days (3) #7 • File serving/sharing • AFS is a very useful interim WAN file system • NT/UNIX • NT/NT • But it will not work for everything • We should track developments! • HEP - physics applications on NT • Early days • It is possible • There are farms D.P.Kelsey - HEPNT update - HEPiX/RAL

  12. Meeting #8 (CERN) 28/29 Jan 99 • WAN file sharing • INFN proposal for WAN NT domain • Identified need for tests of RAS/PPTP over Internet • AFS/NT is still the interim solution • WWW is likely to be the future • Windows 2000 (NT5) • several test domains exist • more are coming (e.g. a CERN WG) • useful to collaborate on migration to Windows 2000 • Aim to complete web pages by June 99 D.P.Kelsey - HEPNT update - HEPiX/RAL

  13. HEPNT Future Plans (1) • Closed meeting - 20/21 May 99 (DESY Zeuthen) • agenda will include... • Status of HEPNT web pages • plans for Windows 2000 • review mandate • report back to HTASC/HEPCCC • If HEPNT’s mandate is not renewed... • Windows 2000 migration group? D.P.Kelsey - HEPNT update - HEPiX/RAL

  14. HEPNT Future plans (2) • More open HEPNT meetings? • The HEPNT Days participants decided “Yes” • And suggested joint meetings with HEPiX • A proposal… • Let’s try a joint HEPiX/HEPNT meeting next time (USA, Autumn 99) • The HEPNT group prefers an extended meeting rather than parallel sessions • 4 or 5 days? • What does HEPiX think?
