6What 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.
7What 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_at_Home searching for life in galaxy,
Austrophysics_at_Swinburne for pulsars) - People/collaborators.
8A View of the Grid Infrastructure
9What 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 standardisation efforts (common, open
protocols). - Killer applications?
10Grid Activities in Cyprus
- Focused around the University of Cyprus.
- Funded by European Commission through IST-FP5.
- Currently, three running projects
- BioGrid
- CrossGrid
- SeLeNe
11Grid 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.
12CyGrid
- 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
14CG 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.

18CyCA 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 that are
allowed access to the grid resources and hosts.
19Crossgrid CA's
20CyCA Acceptance
- List of mutually recognized Certification
Authorities and their status maintained in the
Acceptance Matrix of Brian Coghlan, TCD.
