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

GUI and generic application design
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

GUI and generic application design
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

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

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

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

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

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.
