System and method for computations utilizing optimized earth model representations

摘要

A method and corresponding system is provided for computation utilizing an earth model representation via a computing system having a first processor having access to an earth model dataset. The method includes compressing the earth model dataset at the first processor to generate a look-up table and a set of data indices (i.e., collectively a compressed earth model representation), wherein the look-up table includes quantized data values. By then storing the look-up table in a first level (“fast”) memory, and storing the indices in a second level (“slower,” higher memory capacity) memory, the look-up table and the indices can be accessed to selectively decompress the compressed earth model representation at the first processor such that the computation can be performed efficiently by the first processor.

1. A method for computation utilizing an earth model representation, the method being executed via a computing system having a first processor having access to an earth model dataset, the first processor being operatively in communication with a first level memory and a second level memory, the second level memory being slower but with a higher memory capacity than the first level memory, the method comprising:
compressing the earth model dataset via the first processor to generate a compressed earth model representation, the compressed earth model representation comprising a plurality of data indices and a look-up table comprising quantized data values, by quantizing the earth model dataset to generate at least one of the quantized data values; storing the look-up table in the first level memory; storing the indices in the second level memory; and accessing the look-up table from the first level memory and the indices from the second level memory to selectively decompress the compressed earth model representation at the first processor to enable the computation by the first processor.
