AB: An integrated software framework for geophysical data processing was designed by extending a seismic processing system developed previously. Unlike other systems, the new processing monitor is essentially content-agnostic, supports structured multicomponent seismic data streams, multidimensional data objects, and employs a unique backpropagation execution logic. This results in an unusual flexibility of processing, allowing the system to handle nearly any geophysical data. The core package includes nearly 190 tools for seismic, travel-time, and potential-field processing, interfaces to popular graphics and other packages (such as Seismic Unix and GMT). The system also offers an extensive processing environment, including: 1) a modern and feature-rich Graphical User Interface allowing submission of processing jobs and interaction with them during run time, 2) parallel processing capabilities, including load distribution on Beowulf clusters or local area networks; 3) web service operation allowing submission of complex processing jobs to shared remote servers; 4) automated software update service for code distribution to multiple systems, 5) automated online documentation, and 6) software development utilities. The core package was used in several areas of seismology (shallow, reflection, crustal wide-angle, and teleseismic) and in 3D potential-field processing. As a first example of its application, the new web service component (http://seisweb.usask.ca/SIA/ws.php).was used to build a library of processing examples, ranging from simple (UTM coordinate transformations or calculation of great-arc distances) to more complex (such as synthetic seismic modeling).
