BReSC and CeRB
Bristol: GridPP, GENIE, genomics, digital media,
etc.
UWE: Mammogrid
Exeter: eStar, IAs

BReSC theme
Data-interactivity: NRT DP using local Grid and
display on AG node
Cold and hot media – NRT manipulation and
discovery
Example: finding structure anomalies and features
in multi-dimensional datasets via combination
of display and calculation – astronomy,
mathematics, …

BReSC progress
AGN site preparation – decision for site was delayed, but
now made, orders being placed
eScience PDRA – offer made and informally accepted,
will start in December (Bristol will hire a second
PDRA)
Internal Grid – under test, switches in place
Science drivers – remain strong, additional University
hires in area (Valdes et al.)
SRIF spend – possible significant allocation being
negotiated

6 November 2003
Designed for a wide-field survey
with multiple wavebands and
camera positions
Source detection and merging of
object catalogues
Uses overlaps and stellar colourcolour sequences to produce
uniform photometry
Make, store true-colour images
Single interface to images &
catalogues (local or remote)
Data analysis ‘plug-in’ modules

NeSC, Nov 2003
WFSV: data-analysis modules
Slit-mask design: interactive slit edits, overlap
checks
Photometry plots:
e.g. cluster colourmagnitude diagram
Surface density plot:
colour-magnitude
selected samples
Remote databases: e.g.
FIRST catalogue, maps

GENIE?
Grid ENabled Integrated Earth system model
• Investigate long term changes to the Earth’s climate using g
numerical models
• e-Science aims:
– Flexibly couple state-of-the-art components to form unified
Earth System Model (ESM).
– Execute resultant ESM on a Grid infrastructure.
– Share resultant data produced by simulation runs.
– Provide high-level open access to the system, creating and
supporting virtual organisation of Earth System modellers.

The problem: Thermohaline circulation
•

•
•
ƒ
ƒ
Ocean transports heat
through the “global
conveyor belt.”
Heat transport controls
global climate.
Wish to investigate strength
of model ocean circulation
as a function of two external
parameters.
Use GENIE-Trainer.
Wish to perform 31×31 = 961 individual simulations.
Each simulation takes ∼4 hours to execute on typical Intel P3/1GHz,
256MB RAM, machine ⇒ 163 days

Scientific achievements
Intensity of the thermohaline circulation as a
function of freshwater flux between Atlantic
and Pacific oceans (DFWX), and mid-Atlantic
and North Atlantic (DFWY).
6 November 2003
Surface air temperature difference between
extreme states (off - on) of the thermohaline
circulation.
North Atlantic 2°C colder when the circulation
is off.

Real science through real e-Science
• Delivered Grid resources to perform simulations of
prototype Earth System Model.
• Delivered web based system to allow a virtual
organisation of environmental scientists to create and
manage simulations at a high-level.
• Delivered database management system to allow
scientists to share, access and visualise data
produced by simulation runs.
New results with profound implications: papers
out!
