Track summary

Received 38 abstracts 33 oral presentations, 5 posters

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

configuration and workflow Computing studies: compilers, parallel,

performance optimization Communication and information management







3


GUI and generic application design

ROOT GUI status update Impressive amount of

work done Solid and rich basis New GUI builder Improved interaction

with Qt

Fons Rademakers, ID 187







4



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

QuickTime™ and aTIFF (Uncompressed) decompressorare needed to see this picture.Release and distribution mangement, job configuration and workflow

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







7


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

Release and distribution mangement, job configuration and workflow

Marco Mambelli, ID 35







8

QuickTime™ and aTIFF (Uncompressed) decompressorare needed to see this picture.Computing studies: compilers, parallel, performace optimisation

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







9


Communication and information management

Prototyping a HEP ontology Separate data from presentatio

needs more structure in the data GUI tool developed at SLAC to

describe an ontology (Protege2000) Presently generates RDF Schema

First attempt to describe the domain of HEP Targeting educational aspects

initially

Bebo White, ID 29







10


Communication and information management

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

SLAC, Desy, FNAL support HEPNames comprehensive and widely used directory of

individuals involved in HEP and related fields includes for example: experiment you are

in, date of your PhD, active or not, ... Proposal to extent FOAF to include info from

HEPNames providing an expanded,machine-readable

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