  5. ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 5

  6. New look Portal Under Development ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 6

  7. INO Wiki • Implemted using Joomla!, a popular Content Management System • All about INO activities • Electronics, Magnet, RPC... • The place for information, documentation, Howto's, Writups, etc.. • Public content, password accessed content • Joomla! is based on PHP, MySql ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 7

  8. Joomla! as INO Wiki ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 8

  9. 2. Collaboration tools for INO ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 9

  10. Collaboration Tools • INO is an open collaboration • Communication and documentation - two very important elements of successful collaboration • Share news, announcements, ideas, data, drafts of papers, mailing lists, keep in close contact • Work Logs: Every bit of work, success/failure, to be recorded • Preserving all developments, especially source codes ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 10

  11. Managing Conferences, Workshops.. • Indico- a popular conference management utility, (CERN, SISSA..) • Indico server at INO since 2006 – • Win07, RPC2007, IWPSD2007, Optoschool2008, Workshop on Physics at LHC (2009), IDS-NF Meet, Nufact2010, Lepton Photon-2011 • Data on RAID6 filesystem • Data back up regularly, standy server ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 11

  12. Discussion Forum • Discussion forum - an indispensable component of collabotation • HyperNews (hypernews.org, SLAC), implemented for INO in Sep 2008 • Multiple forums for different interests • Restricted access, moderated account creation • Posting by email as well as login to website • 106 members from various Univs/Insts in India ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 12

  13. Work logs for the collaboration • Detailed work logs and documentation – absolutely essential in experiments • INO work on several fronts, multiple rooms, multiple organizations • Need to track work, daily basis • Implemented a web based Electronic log books ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 13

  14. ELOG • “Web log”, by Stefan Ritt (PSI, Zurich) • Multiple e-logbooks, time stamped entries, attachments, WYSIWYG editor, tables, searches, threads • Chosen for its simplicity and features - • its own webserver, secure connections over SSL, • no database required, data in plain ASCII format • Password protected, over SSL • Data on RAID6 filesystem, also backed up regularly ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 14

  15. INO's ELOG ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 15

  16. INO Mailserver • Dedicated mail server (user@ino.tifr.res.in) • Mail server for INO members • Required for mail enabled packages (Indico, Elog, Hypernews) • IMAPS: for secure access to mailbox with from inside and outside TIFR ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 16

  17. 3. Networks ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 17

  18. INO Network: Geographical issues RPC Lab Near Animal House D Block 4th Floor DAQ Lab TIFR LAN Optical Fiber cable Commissioned by INO C Block 2nd Floor DAQ Lab D Block 3rd Floor C Block 1st Floor C Block Gnd Floor Server Room MTNL Switch Room (Brahmagupta) ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 18

  19. INO LAN within TIFR LAN: Why? • Different centers of activity and DAQ • Common place of data storage, shared home directories, analysis, repositories, printers • Limited supply of public IP numbers • Network enabled DAQ components • Need for keeping some hosts behind firewall • Outgrown the 100Mbps network of TIFR ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 19

  20. Private LANs and Gigabit LANs Room C217 RPC Prototype Stack, DAQ several desktops, Data analysis, disk storage, printer Room D423 RPC testing, desktops.. CAT5E CABLE Pvt LAN Gigabit PVT LAN Students' HALL Cblock 1st Floor C130 Common Room CG18B in CC Server Room - Disk servers, DNS Computing Farm ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 20

  21. 4. Computing Systems for Physics Work ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 21

  22. Desktops and Computing • Large number of students on different steps of academic ladder (VSRP to PostDocs, Staff) • Common (HEP) physics packages • Similar versions of packages for all • Identical software environment • Provide enough disk space • Preserving the work after students move out ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 22

  23. Desktop Environment • Linux based desktops,uniform version of Scientific Linux (recompiled RHEL, maintained by CERN+FNAL) • Desktops as a Linux “cluster” • distributed username-password • common shared home directories • DNS, networked printers, single webserver for everybody's personal homepages • Wifi, too ( with suggested precations) ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 23

  24. Cluster services • Homedir: NFS shared RAID6 filesystem • RAID ≠ Backup: so homedir backed up every midnight (three previous backups always available.) • NIS for same username on all desktops • Print server for identically named print queues • Serving software packages, INO data • All servers on gigabit network in CG18B ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 24

  25. INO Simulation Cluster • Set of compute nodes, on private gigabit LAN • 96 CPU Cores - All Xeons (the old single core, dual and new quad cores) – all rack mounted 1U servers • All computed nodes behind a Master • Common home directories, common software product instances • Enhanced access by extending Gigabit network to Students Hall on 1st floor • Ganglia Monitoring, Batch queue system ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 25

  26. Software repository • Large number of physics packages • Often, same product has different “instances” (versions and flavors 32 or 64 bit, gcc version) • Use of UPS/UPD (Unix Product Support, a Fermilab product) • maintain multiple instances may products • invoke any instance, resolving dependencies • Working to modify UPS/UPD for INO specific products ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 26

  27. The many packages ROOT QtROOT Pythia Genie Lepto CERN LAMPS CERN-Source Matlab Nuance QT4 Octave GEANT4 Mathematica BigStack ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 27

  28. Thank you ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 28
