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

2. Collaboration tools for INO


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


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


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


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


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


15

INO's ELOG


16

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


17

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

4. Computing Systems for Physics Work


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


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)


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


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


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


27

The many packages

ROOT

CERN

Pythia

Lepto

QtROOT

CERN-Source

Octave

Mathematica

Nuance

Genie

QT4

GEANT4

Matlab

BigStack

LAMPS
