2. EOP-A Research and Technology Development Section SpaceGRID Goals Assess how GRID technology can serve requirements across a large variety of space disciplines and applications. Foster collaboration and enable shared efforts across space applications Sketch the design of an ESA-wide (horizontal and common) GRID infrastructure Proof of concept through prototyping Involve both industry and research centres Keep Europe up with GRID efforts !!

3. EOP-A Research and Technology Development Section SpaceGRID Study Financed under Agency’s General Study Programme 800KEuro Datamat, main contractor, subcontractors: Alactel Space Industries, CS Systémes d’Information, Qinetic, Rutherford Appleton Laboratories, Science Systems (Space) Ltd 1 Technical Officer + 4 Domain experts from Agency: –Eamonn Daly, Hugh Evans (Space Weather) –Hans-Peter De Koning (Spacecraft Engineering) –Gerhard Kreiner, Salim Ansari (Solar System Research) –Patrick Grimont (Future EO Ground Segments) September 2001-July2003 Co-operation with EC financed projects DataGRID, EGSO

4. EOP-A Research and Technology Development Section Radiation Transport Geant4 Application Monte-Carlo simulation of high energy particle interactions inside a spacecraft system, components or detector. Large numbers (>10 7 ) of source particles are required to ensure good statistics. Easily adaptable to a parallel processing system (independent particle histories).

5. EOP-A Research and Technology Development Section Spacecraft/Plasma Simulation Monte-Carlo 3-d time dependent electrostatic kinetic Particle-in-Cell Method. Large Number of particles (>10 9 ) to be tracked per iteration. Strong coupling between cells required to solve the field. Challenging to develop sufficiently independent subtasks for parallel processing.

6. EOP-A Research and Technology Development Section Space Weather Simulation Simulation of a Coronal Mass Ejection and interplanetary shock from the Sun to the Earth and subsequent effects on the Earth’s magnetosphere Magneto Hydrodynamic Simulation (MHD). Particle simulation of shock effects on trapped particle belt population (adiabatic responses). Trade-off GRID vs LCMPP and “@home” solutions
