PDPTA'08 Invited Talk - Rajkumar Kettimuthu
Reliable Data Movement Framework for Distributed Science Environments
Argonne National Laboratory, Argonne, Illinois, USA

Time: 4:20 PM
Location: Ballroom 4
Today the science environment is very different from that of a few years ago. Large-scale collaborative science is becoming increasingly common, involving thousands of collaborators distributed across national laboratories and universities and generating massive amounts of data that must be transferred across wide area networks. Simulation sciences such as climate, computational chemistry, fusion, and astrophysics, as well as experimental sciences such as high-energy physics, nuclear physics, light sources, and fusion, are poised to produce enormous quantities of data. However, this data is useful only if it can be effectively accessed and analyzed - tasks that are challenging not only because of the sheer size of the data but also because of the distributed environment in which data is stored and analysis occurs. Critically needed is coordination of numerous shared resources, including CPUs, storage, and networks. In this talk, I will provide an overview of an extensible framework that we are developing for reliable, high-performance, secure, and policy-driven placement of data within a distributed science environment. I will also discuss the tools we are developing for managing the space, bandwidth, connections, and other resources needed to transfer data to and from a storage system.
