System and method for computations utilizing optimized earth model representations

A system for computation utilizing an earth model representation, comprising:

• a first level memory;
• a second level memory being slower but with a higher memory capacity than the first level memory;
• a first processor having access to an earth model dataset, the first processor being operatively in communication with the first level memory and the second level memory;
• non-transitory computer readable media accessible by the first processor, the computer readable media comprising computer readable code for:
• compressing the earth model dataset at 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.
