  • Optimized matrix and vector operations in instruction limited algorithms that perform EOS calculations
    Patent number: 9489176
    Abstract: There is provided a system and method for optimizing matrix and vector calculations in instruction limited algorithms that perform EOS calculations. The method includes dividing each matrix associated with an EOS stability equation and an EOS phase split equation into a number of tiles, wherein the tile size is heterogeneous or homogenous. Each vector associated with the EOS stability equation and the EOS phase split equation may be divided into a number of strips. The tiles and strips may be stored in main memory, cache, or registers, and the matrix and vector operations associated with successive substitutions and Newton iterations may be performed in parallel using the tiles and strips.
