UREC Lyon
What is IST2001?

the IST projects Exhibition is dedicated to displaying
the results of projects within the European
Commission’s Research and Development programmes.
 The Exhibition offers substantial commercial and PR
possibilities, with a peak attendance of over 3500
people last year, plus some 100 journalists from the
trade and general press (data from EU)
 The DataGrid project has been selected to participate to
the exhibit
 When?
From 3 to 5 December in Dusseldorf
The DataGrid Exhibit

Applications:
– Demo A.I: DataGrid and the secrets of the matter (WP8)
– Demo A.II: DataGrid for human health (WP10)
– Demo A.III: DataGrid for the quality of life in our planet
(WP9)
– Show A.I: DataGrid for the quality of life in our planet
(Video ESA)

Middleware:
– Demo B.I: The Grid at work, new business models for
service provider (WP2, Grid simulator)

General info on the project
– Show C.I: The DataGrid portal
– Brochure and posters

Introduction

Goal : send messages to the visitors
– Genomics on an unprecedented scale
– Medical imaging on the grid : a big step towards
telemedecine
– Very High Speed Networks : monitoring and topology

Implementation : flash 5.0
– Professional job
– Animation (http://www.levitated.net/daily/cylinderSEM.html)
GPS@
(see C. Blanchet’s talk)

Gridified copy of NPS@ (http://npsa-pbil.ibcp.fr)
– Same user interface
– Addition of Globus scripts to run jobs on testbed1

Globus scripts invoke grid visualization
– GPS@ runs on dedicated resources

Use of true or fake sequences ?
– True results already computed for quick demo
– Copy of GPS@ server and execution on local machine
for bio-aware visitor ?
Simulator

Goal : simulate the submission of jobs on the grid
– Independent of network connection in Düsseldorf

First implementation by JC Jouannel
http://ccwp7.in2p3.fr/
 Improvements
– List of sites
– Flash ? (after IST2001)
Medical imaging animation

Goal : A 3D medical image example, to display
what kind of medical applications will be
improved by the Grid
 First implementation by J. Montagnat

GÉANT

Broad objective : high bandwidth
network
– which interconnects the national research
and education networks (NREN) in Europe
– which offers guaranteed performance and
virtual private network capability to groups
of end users.

deployed for the end of November
GEANT logical Topology
Cooperation between
DataGRID and GEANT

Technical areas of collaboration:
– input to the specification of the GÉANT
–
–
–
–
managed bandwidth service
traffic and performance monitoring,
development of accounting procedures,
specification of necessary security services
(Ipsec...)
testing of new services (differentiated
services, IP multicast...).
Testbed Monitoring
Results from WP7

Metrics
– Throughput: the rate at
which an application's traffic
must be carried by the network
– Latency : the delay that an
application can tolerate in
delivering a packet of data
– Jitter : the variation in
latency
– Loss : the percentage of
lost data

Tools
– PingEr
– IPERF
– RTPL
– NWS…
