1. SpaceGRID Grid Developments for Space related applications DataGrid Tutorial ESRIN, 10/12/2003 Stefano Beco DATAMAT S.p.A. stefano.beco@datamat.it

2. Introduction to SpaceGRID What is it? A European Space Agency funded project with: • a study component aimed at analysingthe issues (technology, infrastructure, suitable applications) and propose a roadmap for the seamless access to, and exploitation of, distributeddata, application and resources in a network of heterogeneous computing resources • a prototype component aimed at implementation of small-scale dedicated test-beds based on existing infrastructure DataGrid Tutorial - ESRIN

3. Introduction to SpaceGRID Which goals? • Assess how Grid technology can serve requirements across a large variety of space disciplines • Foster collaboration and enable shared efforts across space applications • Sketch the design of an ESA-wide (and common) Grid infrastructure • Proof of concept through prototyping • Involve both industry and research centres • Keep Europe up with Grid efforts DataGrid Tutorial - ESRIN

4. Introduction to SpaceGRID Which focus? Four space related disciplines have been preliminarily identified as potential candidates: • Earth Observation • Space Research • Space Weather simulation • S/C Plasma interaction • Radiation Transport simulation • Solar System Research • Spacecraft (Mechanical) Engineering DataGrid Tutorial - ESRIN

5. Rutherford Appleton Laboratory Introduction to SpaceGRID Who is composing the Consortium? • Industrial partners and research institutions • with strong complementary backgrounds in application disciplines, • already involved in several on-going activities on Grid development at National and EU level.

10. SpaceGRID Results How different are the domains? Space Research DataGrid Tutorial - ESRIN

11. SpaceGRID Results How different are the domains? • After the assessment of User Requirements from all different domains involved in the study, two main “classes” can be identified: • Model-oriented/Simulation-based domains:Space Weather, Spacecraft Plasma Interaction, Radiation Transport • Data-oriented/Application-based domains:Earth Observation, Solar Systems Research • Mechanical Engineering could be seen as across the two “classes” • This means that an ESA-wide Grid infrastructure has to be capable to cope with applications coming from both “classes” of domains DataGrid Tutorial - ESRIN

12. SpaceGRID Results Common User Requirements (1/2) • Support of heterogeneous user communities • Capability to use heterogeneous and distributed computing resources • Provision of distributed computational and data storage services to end users • Follow the evolution of services and specific applications data models • Web portal to access distributed resources and services DataGrid Tutorial - ESRIN

13. SpaceGRID Results Common User Requirements (2/2) • Security: protect data and applications from any unauthorised access, grant access to services and resources only upon registration • Support of collaborative work in distributed environments: common visualisation tools, common working areas • Need for a robust Grid environment DataGrid Tutorial - ESRIN

14. SpaceGRID Results Common I/S Requirements (1/2) • Hardware: • Preferably Linux • Web Server for Portal • Development and Production Test bed • Network: • Enough intra-site bandwidth (100 Mb/s – 1 Gb/s ) • Enough inter-site bandwidth (100 Mb/s – 1 Gb/s ) • Secure, reliable and available network • Web Server for Portal with the same bandwidth requirements • In/Out-bounding connectivity also of worker nodes DataGrid Tutorial - ESRIN

15. SpaceGRID Results Common I/S Requirements (2/2) • Middleware: • Open Source middleware, possibly based on Web Services • Security infrastructure • Information Service, with producer/consumer mechanism • Monitoring Service, with producer/consumer mechanism • Resource Discovery Service • Language to specify/describe resources • Application-independent User Interface • Installation/Configuration Services (CE, SE, SW) • Organisational: • Network/System Administrator availability • Virtual Organisation (VO) Manager • Certification Authority per VO • Community Accounting Services per VO • Collaborative Environment policies DataGrid Tutorial - ESRIN

17. SpaceGRID Future What’s next? • After the conclusion of SpaceGRID study, we are convinced that most (if not all) outcomes are worth to be further investigated and possibly exploited: • by ESA, preparing plans for continuation of this activity, maybe focussed on each specific targets/domains • by each partner, bringing the know how to possible customers and/or other contexts DataGrid Tutorial - ESRIN
