egee grid project
EGEE – Grid project
  • M. Petitdidier (IPSL/CETP)
  • Coordinator of Earth science domain
  • In collaboration with EGEE and DEGREE EU-project
acute questions for earth science
Acute Questions for Earth Science
  • Forecasting of meteorological events
    • Extreme events: storm, tornado, hurricane, earthquake, tsunami…
    • Water management: precipitations, flood, aquifer..
    • Pollution,,…
    • => To provide real time information: real time data access, data assimilation and modelling
  • Long term prediction : Climate Change
    • Climatology i.e. trend of parameter variations like temperature, precipitations….
    • Polar ozone hole
    • Impact on weather, agriculture…
    • => Long series of multiple data sets, Intense processing,
  • Discoveries and Dissemination of the knowledge
    • How it works, Why….
    • These are Questions for
    • Operational and Science organisations
grid a solution
GRID: a solution
  • GRID infrastructure Since 2000
    • Considered an “open platform” for handling computing resources, data, tools…
  • Partner can use a lot more resources than the ones he (she) brings in
    • Impressive number of shared resources
      • EGEEII around 40,000 CPUS distributed in 200 sites
      • 5 PB storage
  • A collaborative possible platform among teams and/or countries
      • interactive collaboration to avoid effort duplication
  • Secure and restricted access to resources, data, tools…
      • Same data and software policy as outside Grid
  • Grid will open new fields of investigation on Earth Science

Highlights of EGEE-II

EGEE Production Grid Infrastructure

Steady growth over the lifetime of the project

Improved reliability

Data Transfer





98k jobs/day

  • Size of the infrastructure today:
  • 237 sites in 45 countries
  • ~36 000 CPU
  • ~ 5 PB disk, + tape MSS
  • distributed operations
  • copes well with increase in size and usage

final remarks
Final Remarks
  • New tools needed to use the whole Grid potential
    • Due to Change in scale of computing power
    • Need of Exploration of huge data sets
    • Creation of Platform integrating web services, computing power, information systems….
  • New conceptual approach of Earth Science
    • Role of Scientist
    • Application development

DEGREE EU project is preparing the future

Strategic objectives
    • Bridge the ES and GRID communities throughout Europe
    • Ensure that ES requirements are satisfied in next Grid generation
    • Ensure the integration of emerging technologies for managing ES knowledge

  • The DEGREE team:
    • IISAS, Slovakia (Coordinator)
  • CNRS, France
  • KNMI, The Netherlands
  • UNINE, Switzerland
  • CRS4, Italy
  • SCAI, Germany
  • GCRAS, Russia
  • ESA-ESRIN, Italy
  • CGG, France
  • Dutch Space, The Netherlands

Project Vision

Build a bridge linking the ES and Grid communities

european grid initiative
European Grid Initiative
  • Need to prepare permanent, common Grid infrastructure
  • Ensure the long-term sustainability of the European e-Infrastructure independent of short project funding cycles
  • Coordinate the integration and interaction between National Grid Infrastructures (NGIs)
  • Operate the production Grid infrastructure on a European level for a wide range of scientific disciplines

Must be no gap in the support of the production grid


Routine Usage


Utility Service
