Inversion of Geophysical Data on Computer System Having Parallel Processors

摘要

A method for efficient use of a computing system of parallel processors to perform inversion of geophysical data, or joint inversion of two or more data types. The method includes assigning at least one control processor to control sequence of operations and reduce load imbalance, assigning a group of one or more processors dedicated to updating one or more model parameters, and assigning another group of one or more processors dedicated to forward modeling simulated data.

1. A method for efficient use of a computing system of parallel processors to update a geophysical model, the method comprising:
assigning at least one control processor to control sequence of operations and to reduce load imbalance between the processors, and assigning a first dedicated processor group of one or more processors to update one or more model parameters in the geophysical model; assigning a second dedicated processor group of one or more processors to simulate forward modeling simulated data; and performing an iterative geophysical model optimization, wherein each iteration comprises:
using the geophysical model to simulate measurement data;comparing simulated data to measurement data; andupdating the geophysical model to lessen misfit based on the comparison.
