  1. Grid Activities in CyprusMarios DikaiakosUniversity of Cyprus

  2. Overview • A few words about the Grid • Grid activities in Cyprus • CyGrid and the Local Testbed • Program of talks

  3. The Dead Supercomputer Societyand the “killer micros” Once upon a time…….. Microcomputer Mini Computer Cluster (by Christophe Jacquet)

  4. The GRID distributed computing idea …and today (by Christophe Jacquet)

  5. Why Now? Moore’s Law vs. storage improvements vs. optical improvements. Graph from Scientific American (Jan-2001) by Cleo Vilett, source Vined Khoslan, Kleiner, Caufield and Perkins.

  6. What is a Grid? • Collaborative set of computing, data storage and network resources belonging to different administrative domains that has knowledge about the status of its components through active, distributed information services. • Uses standard, open, general-purpose protocols and APIs. • Allows certified users belonging to multi-domain Virtual Organizations to access a large amount of resources via single log in. (sign on). • Offers a simple, consistent, dependable, and pervasive access across wide-area networks and presents users with an integrated global resource. • Manages concurrent access by large numbers of dispersed users.

  7. What is a Grid ? • An infrastructure that couples: • Networked Computers – PCs, workstations, clusters, supercomputers, laptops, notebooks, mobile devices, PDA, etc; • Software – e.g., ASPs renting expensive special purpose applications on demand; • Catalogued data and databases – e.g. transparent access to human genome database; • Special devices– e.g., radio telescope – SETI@Home searching for life in galaxy, Austrophysics@Swinburne for pulsars) • People/collaborators.

  9. What it takes to build the Grid? • New programming tools. • Software that can translate the requirements of an application into requirements for computers, networks, and storage. • Security mechanisms that permit resources to be accessed only by authorized users. • Computers and operating systems that are more tightly integrated with high-speed networks. • Strong standardisationefforts (common, open protocols). • Killer applications?

  10. Grid Activities in Cyprus • Focused around the University of Cyprus. • Funded by European Commission through IST-FP5. • Currently, three running projects: • BioGrid • CrossGrid • SeLeNe

  11. Grid Projects in Cyprus • BioGrid (September 2002 / 24 months) • Development of a research infrastructure for large genomics and proteomics databases applications. • Globus • CrossGrid (March 2002 / 36 months) • Grid Infrastructure for Interactive applications. • EDG/CG • SeLeNe (November 2002 / 12 months) • Feasibility study of using Semantic Web technology for dynamically integrating metadata from heterogeneous and autonomous educational resources.

  12. CyGrid • An activity funded in the context of the CrossGrid project. • Goal: • Establish the local node of the pan-european CrossGrid testbed. • Establish a Certification Authority for Cyrpus. • Promote the uptake of Grid technologies in Cyprus and the deployment of new applications on the CyGrid testbed.

  13. What is the “CrossGrid testbed” ? • A collection of distributed computing resources • Supporting a “Grid environment” • Objectives • Development, Testing and validation • Emphasis on interoperability with EU-DataGrid (EDG) • Extension of GRID across Europe

  14. CG Testbed Overview • A collection of distributed computing resources • 16 sites (small & large) in 9 countries, connected through Géant + NRN • 115 CPUs (Worker Nodes) • 4 TB (Storage Elements) • + Grid Services: Middleware (based on Globus,EDG) RB, VO, RC… • A group of people and resources make up the CrossGrid Virtual Organization (VO) and trust each other through national Certification Authorities.

  18. CyCA: The Certification Authority of CyGrid • Established within the EU project "CrossGrid" & the CyGrid testbed. • Goal: to enable researchers to safely use the Grid. • Main operation: provides X.509 certificates for identification and authentication purposes related to Grid activities. • CyGrid CA is independent of any single organization. • Signs certificates for individuals thatare allowed access to the grid resources and hosts.

  19. Crossgrid CA's

  20. CyCA Acceptance • List of mutually recognized Certification Authorities and their status maintained in the Acceptance Matrix of Brian Coghlan, TCD.
