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

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

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

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

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

INO Mailserver

Dedicated mail server ([email protected])

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

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

21
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

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

23
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

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

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
