The HEPGrid Project - High Energy Physics and Grid Network
This project aims to design and develop a safe, secure, dynamic and adaptive Data Grid Resource Broker for managing and scheduling data intensive science applications on geographically distributed resources. The broker will engineered to logically couple with data sources to perform online extraction data from closest data sources or replicas depending on user requirements. The broker selects data sources depending on their cost and user defined quality of services to optimize the use of resources. It evaluates whether to process on a resource where data is available by moving the application code, moving data to a resource where the application is available, or move the data and the application to a resource whether computing power most economically is available. This is a significant challenge in the design and evaluation of scheduling algorithms. These will then be incorporated into application scheduler. The requirements for the Data Grid Broker scheduler will be derived from two application areas: High Energy Physics and Molecular Modeling for Drug Design.
Building upon the earlier work of Experimental Particle Physics Group at the the University of Melbourne, we plan to port the Belle Experiment analysis code to the GRID framework. Belle is an experiment based at the KEK, Laboratory in Japan that is right now accumulating tens of terabytes of data per year. Our plan is to initially test the suitability of the GRID framework to handle a real running experiment and then to be deployed as the computing solution for the Belle experiment.
The proposed Kangaroo Data Grid broker leverages existing grid middleware systems such as Globus and Nimrod-G. The framework for Problem Solving Environment builds on existing works and extends its capability to support tasks grouping, dependencies and flow graphs. The user-level data management and caching techniques will be developed for smart scheduling and also for sharing results of event processing with other researchers.
