Abstract
This invention provides a method for inputting seismic trace data to a seismic processing program running on a massively parallel processor (MPP). The MPP, consisting of a plurality of individual processing nodes connected by a data and control communications network, is treated as a bipartite system of "operator" nodes and "input" nodes. Operator nodes apply mathematical operators to transform seismic data. Groups of seismic traces are loaded into the input nodes. The input nodes examine the data to determine which regions of the seismic survey are covered by the traces. The input nodes then broadcast to all operator nodes a compact description of the trace coverage. The operator nodes then retrieve traces from the input nodes, using efficient data transfer mechanisms of the data network. The input nodes can be seen to serve as a distributed, content-addressable data cache. In the preferred embodiment of the invention, the input nodes read trace data from a disk storage system using techniques that are efficient over a large range of numbers of nodes in the MPP and disks in the disk system. Thus, the invention provides an efficient method that can be used with MPP systems of vario…
