3
BReSC and CeRB

• Bristol GridPP, GENIE, genomics, digital media,
  etc.
• UWE Mammogrid
• Exeter eStar, IAs
• Bristol BReSC a component of CeRB

4
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,
  

5
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

Projects

• Some examples
• WFSviewer
• GENIE
• InSAR
• Isomerisation
• Others
• Bristol digital media, genomics, earthquake
  modelling, volcano predictions
• Exeter eStar, Ias
• UWE Mammogrid

7
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

8
WFSV data-analysis modules
Slit-mask design interactive slit edits, overlap
checks
Photometry plots e.g. cluster colour-magnitude
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 Earths
  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.

10
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 31?31 961 individual
  simulations.
• Each simulation takes ?4 hours to execute on
  typical Intel P3/1GHz, 256MB RAM, machine ? 163
  days

11
Scientific achievements
Surface air temperature difference between
extreme states (off - on) of the thermohaline
circulation. North Atlantic 2?C colder when the
circulation is off.
Intensity of the thermohaline circulation as a
function of freshwater flux between Atlantic and
Pacific oceans (DFWX), and mid-Atlantic and North
Atlantic (DFWY).

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!
