BReSC and CeRB

Bristol: GridPP, GENIE, genomics, digital media, etc.

UWE: Mammogrid

Exeter: eStar, IAs

Bristol: BReSC a component of CeRB

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 placeScience drivers – remain strong, additional University

hires in area (Valdes et al.)SRIF spend – possible significant allocation being

negotiated

Wide-Field Survey Viewer

• Designed for a wide-field survey with multiple wavebands and camera positions

• Source detection and merging of object catalogues

• Uses overlaps and stellar colour-colour sequences to produce uniform photometry

• Make, store true-colour images

• Single interface to images & catalogues (local or remote)

• Data analysis ‘plug-in’ modules

6 November 2003 Mark Birkinshaw, U. Bristol 8

NeSC, Nov 2003

Slit-mask design: interactive slit edits, overlap checks

Photometry plots: e.g. cluster colour-magnitude diagram

Remote databases: e.g. FIRST catalogue, maps

Surface density plot: colour-magnitude selected samples

WFSV: data-analysis modules

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• 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 3131 = 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).

Surface air temperature difference between extreme states (off - on) of the thermohaline circulation.

North Atlantic 2C colder when the circulation is off.

NeSC, Nov 2003

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!
