Poster: Using Active Storages for Seismic Data Processing

This poster presents an approach to distributed seismic data processing using Seismic Un*x Software and the Active Storage system based on TSim C++ template library and the Lustre file system. Active Storage concept implies the use of distributed system architecture, where each node has processing and storage capabilities. Data are distributed accross these nodes, computational tasks are submitted to the most suitable nodes, to reduce network traffic. The main benefits of our approach are the following: - Effective storing and processing of seismic data with minimal changes in CWP/SU modules - Performance testing shows that the Active Storage system is effective - Meta-programming with C++ templates permits a flexible implementation of scheduling algorithms The study analyzes performance results of the developed system as well as the usability of Active Storage and Seismic Unix integration. In the nearest future, we will get results for a 1.2 TB data file.
