Abstract

We examine the use of policy-driven data placement services to improve the performance of data-intensive, petascale applications in high performance distributed computing environments. In particular, we are interested in using an asynchronous data placement service to stage data in and out of application workflows efficiently as well as to distribute and replicate data according to Virtual Organization policies. We propose a data placement service architecture and describe our implementation of one layer of this architecture, which provides efficient, priority-based bulk data transfers.
