| Abstract: | Information services play a crucial role in grid environments in that the state information can be used to facilitate the
discovery of resources and the services available to meet user requirements, and also to help tune the performance of a grid
system. However, the large size and dynamic nature of the grid brings forth a number of challenges for information services.
This paper presents PIndex, a grouped peer-to-peer network that can be used for scalable grid information services. PIndex
builds on Globus MDS4, but introduces peer groups to dynamically split the large grid information search space into many small
sections to enhance its scalability and resilience. PIndex is subsequently modeled with Colored Petri Nets for performance
evaluation. The simulation results show that PIndex is scalable and resilient in dealing with a large number of peer nodes.
