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

(2) ‘Information Exchange’ not a ‘Solution Provider’‘Information Exchange’ not a ‘Solution Provider’ no extensive investigations or developmentno extensive investigations or development Where necessary (and possible?),Where necessary (and possible?), –coordinate NT activities –enable interworking between sites –enable interworking NT/UNIX (with HEPiX) We do not intend to standardise the desktopWe do not intend to standardise the desktop We do not recommend (or impose!) single solutions on HEP except where necessaryWe do not recommend (or impose!) single solutions on HEP except where necessary –e.g. compilers

6. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL6 HEPNT meetings 7 (closed) meetings have been held discussing...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

7. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL7 Meeting #6 (CERN) 24/25 Sep 98 NT Internet Services on NICE (Alberto Di Meglio, CERN)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 serversCERN have also tested scalability of NTFS file servers –conclude - can support up to 1000 users/server

8. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL8 Meeting #6 (2) AFS on Windows NT study (R. Toebbicke, CERN)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...HEPNT conclusions... –AFS not recommended as sole home file system –best interim solution for WAN file sharing –use NTFS for NT profiles

9. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL9 ‘HEPNT Days’ at CERN 2-4 Dec 98 Open meeting (#7) - aimed at NT system managersOpen meeting (#7) - aimed at NT system managers 67 participants from 11 countries67 participants from 11 countries The important themes…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

10. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL10 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

11. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL11 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

12. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL12 Meeting #8 (CERN) 28/29 Jan 99 WAN file sharingWAN 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)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 99Aim to complete web pages by June 99

14. 15-Apr-1999D.P.Kelsey - HEPNT update - HEPiX/RAL14 HEPNT Future plans (2) More open HEPNT meetings?More open HEPNT meetings? –The HEPNT Days participants decided “Yes” –And suggested joint meetings with HEPiX A proposal…A proposal… Let’s try a joint HEPiX/HEPNT meeting next time (USA, Autumn 99)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?
