The design and implementation of extensible information services

Abstract

High-performance distributed computing often requires careful selection and configuration of computers, networks, application protocols, and algorithms. In grid environment, the participators of domains provide site information by default that may be not adequate for resources manager to achieve optimal performance. In this paper, an Extensible Information Service Architecture (EISA) is described to resolve this problem. EISA supports a virtual organization participator's autonomous control of local resources. It consists of three layers, the registration and deployment layer, normalization and organization layer, and information collection layer. Dynamic information services in EISA could be deployed and extended easily. EISA improves the extensibility of grid information services and the efficiency of resources utilization. © Springer-Verlag Berlin Heidelberg 2005.
