Executive control of multi-channel operation in seismic data processing system

A large number of functional modules are involved in seismic data processing, only under unified control of the execution control system such a complex systematic project with these functional modules in seismic data processing can be completed, and pipeline technology in existing computer operating system can support the control of single channel operation, but can´t realize the control of multi-channel operation. This paper presented an execution and control method of multi-channel operation based on named pipe and redirection technology, which realized the control of complex multi-channel operation, and implemented the processing of multiple data streams in PBS through the combination of PBS with execution and control procedures. The application experiment results show that this method has strengthened the capability of system to execute and control operations, and improved the efficiency of seismic data processing.
