Introduction to Space. GRID What is it? A European Space Agency funded project with: n a study component aimed at analysing the issues (technology, infrastructure, suitable applications) and propose a roadmap for the seamless access to, and exploitation of, distributed data, application and resources in a network of heterogeneous computing resources n a prototype component aimed at implementation of small-scale dedicated test-beds based on existing infrastructure 10/12/2003 Data.

Introduction to Space. GRID Which goals? n n n 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 10/12/2003 Data. Grid Tutorial - ESRIN 3

Introduction to Space. GRID Which focus? Four space related disciplines have been preliminarily identified as potential candidates: n Earth Observation n Space Research n n n Space Weather simulation S/C Plasma interaction Radiation Transport simulation Solar System Research Spacecraft (Mechanical) Engineering 10/12/2003 Data.

Introduction to Space. GRID Who is composing the Consortium? n Industrial partners and research institutions n with strong complementary backgrounds in application disciplines, n already involved in several on-going activities on Grid development at National and EU level.

Space. GRID Results Space Research How different are the domains? 10/12/2003 Data. Grid Tutorial - ESRIN 11

Space. GRID Results How different are the domains? n After the assessment of User Requirements from all different domains involved in the study, two main “classes” can be identified: n n 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 10/12/2003 Data.

Space. GRID Results Common User Requirements (1/2) n n n 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 10/12/2003 Data. Grid Tutorial - ESRIN 13

Space. GRID Results Common User Requirements (2/2) n n n 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 10/12/2003 Data. Grid Tutorial - ESRIN 14

Space. GRID Results Common I/S Requirements (1/2) n Hardware: n n Preferably Linux Web Server for Portal Development and Production Test bed Network: n n n 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 10/12/2003 Data. Grid Tutorial - ESRIN 15

Space. GRID Results Common I/S Requirements (2/2) n Middleware: n n n n n 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, SW) Organisational: n n n Network/System Administrator availability Virtual Organisation (VO) Manager Certification Authority per VO Community Accounting Services per VO Collaborative Environment policies 10/12/2003 Data.

Space. GRID Future What’s next? n After the conclusion of Space. GRID study, we are convinced that most (if not all) outcomes are worth to be further investigated and possibly exploited: n n 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 10/12/2003 Data.
