Revision of the Detection/Analysis System at SDAC
Abstract
This report presents the computational requirements for a new detection processor and regional analysis system at the Seismic Data Analysis Center (SDAC). In addition, the report considers the computational requirements to support a research environment at the SDAC which would include the detection/ regional analysis capability as well as seismic research, development of new signal processing algorithms and techniques, and seismic experiments and applications of data base management techniques. Based on these requirements, various alternative computer systems are reviewed, including the existing computer facilities at the SDAC. If the new system is to be devoted to the DP/ regional analysis service routinely, then the SEL 32/77 computer with its high input/output and computational bandwidth and its plug compatibility with all IBM peripherals at SDAC will be the most cost effective choice. Moreover, there will be no need to convert old SDAC programs since all software for this application will be new. On the other hand, if the new computer must serve a research environment calling for on-line DP and regional analysis experiments, batch processing for seismic research, and continual softwre development of new processing algorithms and techniques, then the IBM 4341 is the best choice. The new IBM computer is compatible with all existing IBM peripherals at SDAC, can run virtually all existing SDAC programs without modification, and offers the most complete software development tools and versatile operating systems. The additional capital cost of this machine would be more than offset by savings in software conversions and development.
