Abstract

In this paper we describe resource and service discovery mechanisms available in iGrid, a novel Grid Information Service based on the relational model. iGrid is developed within the GridLab project by the ISUFI Center for Advanced Computational Technologies (CACT) at the University of Lecce, Italy and it is deployed on the European GridLab testbed. The GridLab Information Service provides fast and secure access to both static and dynamic information through a GSI enabled web service. Besides publishing system information, iGrid also allow publication of user's or service supplied information. The adoption of the relational model provides a flexible model for data, and the hierarchical distributed architecture provides scalability and fault tolerance.
