GridSim: A Grid Simulation Toolkit for Resource Modelling and Application Scheduling for Parallel and Distributed Computing
http://www.gridbus.org/gridsim/

Peer-to-Peer/Grid computing has emerged as a potential next generation platform for solving large-scale problems in science, engineering, and commerce. It is expected to involve millions of (heterogenous) resources scattering across multiple organizations, administrative domains, and policies. The management and scheduling of resources in such a large-scale distributed systems is complex and therefore, demands sophisticated tools for analysing and fine-tuning the algorithms before applying them to the real systems. Simulation appears to be the only feasible way to analyse algorithms on large-scale distributed systems of heterogenous resources. Unlike using the real system in real time, simulation works well, without making the analysis mechanism unnecessary complex, by avoiding the overhead of co-ordination of real resources. Simulation is also effective in working with very large hypothetical problems that would otherwise require involvement of a large number of active users and resources, which is very hard to coordinate and build at large-scale research environment for investigation purpose. The primary objective of this project is to investigate effective resource allocation techniques based on computational economy through simulation. They like to simulate millions of resources and thousands of users with varied requirements and study scalability of systems, algorithms, efficiency of resource allocation policies and satisfaction of users. They are also interested to explore how significantly the local economy and the global positioning (e.g., the time zone) of a particular resource play role in securing jobs under various pricing and demand/supply situations.
