• Project Leader, "Globally Distributed Object Databases" (GIOD Project), 5/97 to present

Instigator of, and Principal Investigator in a joint project between Caltech and CERN, funded by Hewlett-Packard. Project investigates use of Object Oriented software, commercial Object Databases and mass storage systems as solutions to the PetaByte storage needs of the next generation of high-energy physics experiments. Close collaboration with Caltech's Center for Advanced Computing Research (CACR). Design and implemention scheme for populating Object Database with ~1 TeraByte of physics data using SMP servers and clusters of NT workstations. Develop C++ and Java/3D/JFC applications that run against the database (a featured application at the Fall '98 Internet-2 meeting). Measure scalability and deployment issues. Evaluate Object Database performance on large SMP server with distributed and numerous clients. Combine the Object Database with a hierarchical storage management system. Measuring and compare the performance of systems based on two commercial Object Databases. Model the system behaviour to produce scaling predictor algorithms, with special emphasis on the WAN aspects of the systems. Develop sophisticated event viewers based on Java 3D that interact with the Object Database to directly access and render the complex event structures.
