Realistic modelling in Environmental
And LIfe Sciences Through Escience
Addresses issues of complexity and
knowledge creation and management
myGrid and RealityGrid work is
complementary
Combine with FP5 Grid Projects
Realiste Grid Strategy
„
„
„
„
„
“Connect locally, connect globally”.
Grids are federations on sub and
super-scales.
Grids are about flow of information
not just computation.
A experiment, a supercomputer, a
database are all Grid components.
Define a role for HEC in Grid.
Realiste Components

„
„
„
„
A high quality network – GEANT
Grid middleware – Globus and Unicore
Computing resources, heterogeneous
Centres of data and expertise, EBI, EMBL.
Scientific applications and collaboration
Support and training, national centres of
excellence, e.g CSC, PSC, NIEES
Industrial partners.
Science Drivers
„
„
„
„
Life and environmental sciences face
complexity, need to bring data management
and computation closer.
Can build on data and computation layers of
the Grid, FP5 projects.
Europe has great strength in modelling and
complex Grid applications, lead in GGF
Applications WG
Links with activity in Asia-Pacific, e.g.
Earth Simulator.

Emergent behaviour
•
•
•
•
Self-sustaining global Grids are likely to emerge
from federation of successful VOs
For self-sustaining GRIDs, questions of
accounting, resource transfer and trust are of
central interest.
How much structure for Grid economies to
emerge?
It is important that the structures arise out of
scientific necessity and not solely to create a
Grid.

Links with DataGrid bioinformatics work,
links between physics and biology Grid
work.
Relation to overall European Grid.
Complementary to UK eScience proposal.
Provenance, metadata and workflow for
simulation techniques, GriPhyN workshop
also beginning to address these issues.
