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

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

Managing Conferences, Workshops. . Indico - a popular conference management utility, (CERN, SISSA. . ) Indico server at INO since 2006 – Win 07, RPC 2007, IWPSD 2007, Optoschool 2008, Workshop on Physics at LHC (2009), IDS-NF Meet, Nufact 2010, Lepton Photon-2011 Data on RAID 6 filesystem Data back up regularly, standy server ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 11

Discussion Forum Discussion forum - an indispensable component of collabotation Hyper. News (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

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

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 RAID 6 filesystem, also backed up regularly ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 14

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

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

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

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

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 100 Mbps network of TIFR ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 19

Private LANs and Gigabit LANs Room C 217 Room D 423 RPC Prototype Stack, DAQ several desktops, Data analysis, disk storage, printer RPC testing, desktops. . CAT 5 E CABLE Pvt LAN Gigabit PVT LAN C 130 Comm on Room ASET Colloquium, 23 July 2010 Students' HALL Cblock 1 st Floor CG 18 B in CC Server Room Disk servers, DNS Computing Farm Nagaraj Panyam, DHEP TIFR 20

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

Desktops and Computing Large number of students on different steps of academic ladder (VSRP to Post. Docs, 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

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

Cluster services Homedir: NFS shared RAID 6 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 CG 18 B ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 24

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 1 U servers All computed nodes behind a Master Common home directories, common software product instances Enhanced access by extending Gigabit network to Students Hall on 1 st floor Ganglia Monitoring, Batch queue system ASET Colloquium, 23 July 2010 Nagaraj Panyam, DHEP TIFR 25

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

The many packages ROOT Qt. ROOT Genie LAMPS CERN-Source CERN Pythia Lepto Matlab Nuance QT 4 Octave Mathematica ASET Colloquium, 23 July 2010 Big. Stack Nagaraj Panyam, DHEP TIFR GEANT 4 27
