Abstract:
Traditional Grid monitoring and discovery services are mainly
responsible to discover shared computing resources spanning multiple
administrative domains and present their unified functionality to the users.
Often these discovery services are not fault tolerant, and popular Grid
middleware deploy discovery services which do not tolerate high resources
churn. Moreover, some Grids deploy centralized discovery service solutions
which severely limit the scalability of the Grid. Although solutions such as
heart beat systems for dynamic resource availability, super peer discovery
services which cater for scalability, have been devised to address this
problem. However no unified discovery architecture has been proposed and
implemented for next generation dynamic, decentralized, pervasive Grids. In
this report, architecture is proposed which integrates an autonomic
infrastructure into Grid monitoring and discovery services in order to
provide for a more flexible, robust and self-healing Grid. The proposed
architecture will lead towards a generic implementation which will be used
to transparently extend existing discovery services.
