Using AFS As A Distributed File System For Computational And Data Grids In High Energy Physics

The use of the distributed file system, AFS, as a solution to the “input/output sandbox” problem in grid computing is studied.A computational grid middleware, primarily to accommodate the environment of the BaBar Computing Model, has been designed, written and is presented. A summary of the existing grid middleware and resources is discussed.A number of benchmarks (one written for this thesis) are used to test the performance of the AFS over the wide area network and grid environment. The performance of the AFS is also tested using a straightforward BaBar Analysis code on real data.Secure web-based and command-line interfaces created to monitor job submission and grid fabric are presented.
