Track summary

Received 38 abstracts 33 oral presentations, 5 posters

1 oral arrived as poster, 2 didn’t arrive at all

Four main themes (with “fuzzy” borders) GUI and generic application design Release and distribution management,

validation, job configuration and workflow Computing studies: compilers, parallel,

performance optimization Communication and information management

As time is short, I had to make some (subjective) selection Apologies for this …







3


GUI and generic application design

ROOT GUI status update Impressive amount

of work done Solid and rich

basis Cross platform

New GUI builder Improved

interaction with Qt

Fons Rademakers, ID 187







4



Guidelines for GUI application design Design needs to start with UseCase analysis

Three click rule Miller’s law of 7

Use structure to hide complexity Tabs, sub-menus

Fons Rademakers, ID 188







5



Rome - analysis framework generator Based on root Separate framework

part from analysis part Generate the

classes for the framework automatically

Two modes “Rome only” GUI Can be combined

Matthias Schneebeli, ID 454







6



Testing of distributed GUIs/applications UnitTests not enough Usability tests need to capture

information as user(s) use it Capture screen Capture video/audio From all inputs in distributed

environment Also useful for debugging at a

later time Proof of concept done







7


Release and distribution management, validation, job configuration and workflow

The LCG SPI project in LCG phase II Provides a large set of stable

services Savannah portal, External

Software, Testing Frameworks, Software Distribution, Build and Release, QA Activities

SPI work is guided by the Architects Forum representing the users and

steers priorities Will concentrate more on the

experiments’ needs

Andreas Pfeiffer, ID 229







8



Worm and P2P Distribution in Atlas Trigger/DAQ 6 GB of s/w per release, 600

nodes in various locations Distribution tools not always

available outside CERN Using “hacker technology” to

distribute: Worm: Nile

Distribute tools and commands Peer-to-Peer: BitTorrent

Distribute the s/w

Hegoi Garitaonandia, ID 200







9


The Capone workflow manager Used for Atlas productions

on Grid3/OSG grids Used in various

productions for about 340k jobs in total Failures mainly external

(RLS registration) Improving performance by

using a more flexible execution model


Marco Mambelli, ID 35







10



CMS Simulation Validation Suite Mainly for regression testing Covering all sub-detectors plus

“general” aspects Geometry, Material balance,

magnetic field Will be extended to Physics

software Validation Suite Including Digitisations Adding Physics quantities

Daniel V Elvira, ID 261







11


Release Process very similar in Atlas and CMS Main problem: large

number of developers and geographical diversity

Use different tools for configuration mgt and build

Quite some commonality in process (and (some) tools) Nightlies (nicos) collecting/controlling tags


Solveig Albrand (Atlas), ID 71Stefano Argiro (CMS), ID 246







12



Physics-level job configuration Targeting end-user

physicists Defining configurables

Smart low-level building blocks (auto-generated)

Structuring possible Build higher level structures

needed by physics community

Wim Lavrijsen, ID 146







13



Packaging and distributing CMS software Two very different use-

cases, two solutions DAR minimal set of files

needed for production on the grid including monitoring

XCMSI targeting development environment full set of files GUI for installation

Klaus Rabbertz, ID 247Andreas Nowack, ID 248







14

QuickTime™ and aTIFF (Uncompressed) decompressorare needed to see this picture.Communication and Information Management

HyperNews - managing discussions in HEP First used in BaBar then STAR

This year: Atlas, CMS Combining the positive aspects

of e-mail with web-based bulletin boards

Rich set of features Most recent postings Search engine Central (un)subscription to fora

Douglas Smith, ID 298







15


Parallel computing for the Atlas Si tracker ca 35000 Degrees of Freedom

in the tracker Alignment with a global 2

function Limited by memory size,

precision and execution time Using AMD64 Beowulf cluster at

RAL Carefully checked correctness

and quality Gained factor of about 30

Müge Karagöz Ünel, ID 100

Computing studies: compilers, parallel, performance

optimization







16


Performance Optimization Tools for Atlas HLT Allows to use ESD or AOD as

input to the HLT algorithm for studies and optimisation Output will be part of

ESD/AOD in the future Used for case study of physics

channel (HZZ*4e) Two step process Same efficiency (90%) with

slightly lower rate (82 Hz)

Cibran Santamarina, ID 103


optimization







17


Capturing and archiving lectures for HEP Web Lecture Archive Project

Started with pilot in 1999 Working on a standard for

“Lecture Object” XML extension to SMIL “Seminar” vs. “Tutorial” types

with different requirements Automation using robotic

cameras which track speaker Developed “active IR tracking”

Portable, aim at cost < 10 K$

Steven Goldfarb, ID 344,345

Communication and Information Management







18


Safety integrated into Equiment Management at CERN Safety requirements essential at

CERN also for relations with host states Integrate safety reports into

existing resources (EDMS, EMT) Improve handling and feedback

possibilities Migrate 10k documents from old

system Since Aug 05 700 new entries Very positive feedback from

users

Stephan Petit, Eva Sanchez, ID 115

Communication and Information Management







19



optimization Software kernels - performance

studies using small “snippets” of HEP code 10 snippets from HEP codes

selected and analyzed so far More are planned

Talking to compiler writers to improve the compilers Mainly commercial and gcc Good feedback

Need to care about potential pitfalls Inconveniences are outweighed

by the advantages

Sverre Jarp, ID 31







20

QuickTime™ and aTIFF (Uncompressed) decompressorare needed to see this picture.Communication and information management

Prototyping a HEP ontology Separate data from presentation(s)

needs more structure in the data First attempt to describe the domain of HEP

Targeting educational aspects initially, using RDFS

FOAF (Friend-of-a-friend) is an open standard to describe relationships between people Described in RDF/OWL Proposal to extent FOAF to include info from

HEPNames comprehensive and widely used directory of

individuals involved in HEP and related fields providing an expanded,machine-readable data format

for HEP collaborator information that is understandable by HEP Semantic Web applications.

Bebo White, ID 29+30







21


Dissemination of scientific results: CERN Document Server vision Following CERNs OpenAccess

policy (Berlin declaration) Automatic extraction of

keywords and references User-tools: sort by ranking

(citations and downloads), search (metadata, fulltext), alerts (e-mail)

Option for “open reviewing” and commenting

Never forget to self-archive !

Alberto Pepe, ID 216

Communication and information management







22


Report on RTAG-12 Collaborative tools at CERN

need significant improvement Nine recommendation in report

Need to follow them urgently Collaborative action needed

Resources may have to come from everyone

Collaborative Tool Service needs to be established

Estimate resources and find funding

Start R&D and pilot now

Steven Goldfarb, ID 49








23


HepForge and HEP software development Emphasizing the importance of

small well-designed tools Modularity and interfaces A la unix-tools

HepForge created as part of CEDAR Full development environment

(web, cvs/svn, wiki, tracker, mail-lists, download)

In operation since Jan 06 After beta test of 6 months

Andy Buckley, ID 120








24


From VRVS to EVO VRVS well established and well

used, will stay Next-generation tools will avoid

some of the problems found EVO: adaptive, self-managed

infrastructure Decentralized agents (“Panda”) Distributed w/o single point of

failure “Koala”s at client side contact

“nearest” Panda Multi-platform interoperable

Philippe Galvez, ID 154








25


Integrated issue-based QA system Information system around QA

in STAR Try to identify issues asap

Staged: online, “fast offline”, production

Also used for simulation and nightly tests

Integration with Electronic ShiftLog is essential Browsing and searching “Hub of QA”

Gene Van Buren, ID 157
