摘要：

The Parallel ROOT Facility, PROOF, enables the analysis Of Much larger data sets on a shorter time scale. It exploits the inherent parallelism in data of uncorrelated events via a multi-tier architecture that optimizes I/O and CPU utilization in heterogeneous clusters with distributed storage. The system provides transparent and interactive access to gigabytes today. Being part of the ROOT framework PROOF inherits the benefits of a performant object storage system and a wealth of statistical and visualization tools. This paper describes the data analysis model of ROOT and the latest developments on closer integration of PROOF into that model and the ROOT user environment, e.g. support for PROOF-based browsing of trees stored remotely, and the Popular TTree: :Draw() interface. We also outline the ongoing developments aimed to improve the flexibility and user-friendliness of the system. (c) 2005 Elsevier B.V. All rights reserved.
