Inversion of geophysical data on computer system having parallel processors

A computer system of parallel processors programmed to perform iterative geophysical model optimization, the computer system comprising:

• a computer system including at least one control processor in communication with a plurality of processors;
• memory accessible to the at least one control processor and the plurality of processors, wherein the memory includes a geophysical model, measured data, and a set of instructions which, when executed by the computer system causes,
• the at least one control processor to control to control a sequence of operations and reduces load imbalance between the plurality of processors,
• the at least one control processor to assign some of the plurality of processors to a first dedicated processor group that update one or more model parameters in the geophysical model,
• the at least one control processor to assign some of the plurality of processors to a second dedicated processor group that simulate forward modeling of simulated data, and
• the computer system to perform an iterative geophysical model optimization, wherein each iteration includes:
• the first dedicated processor group and the second dedicated processor group accessing the geophysical model in the memory;
• the second dedicated processor group simulating measurement data from the geophysical model;
• the computer system comparing the simulated measurement data to the measured data stored in the memory, and
• the first dedicated processor group updating the geophysical model to lessen misfit based on the comparing,
• wherein the at least one control processor dynamically balances processing load resulting from the iterative geophysical model optimization across the first dedicated processor group and the second dedicated processor group.

A method of performing a joint geophysical inversion comprising:

• (a) obtaining at least two types of geophysical data;
