  • Apparatus and method for parallelizing legacy computer code
    Patent number: 6339840
    Abstract: A computer-implemented method and apparatus for parallelizing input computer-program code based on class-specific abstractions. The method includes the steps of providing a class-specific abstraction (CSA), and generating parallelization code based on the CSA and the input code. Other aspects include checking the input code for compliance with the CSA, performing a dependency analysis of the input code for compliance with the CSA, analyzing the control flow of the input code based on the CSA, and generating a block-based representation of a control flow based on index variables in the input code and on the CSA. In one embodiment, the CSA includes a computational-set template, a dependency template, and a set of allowed index-variable access patterns. Yet other aspects include generating synchronization points based on the CSA, mapping a computational set to a virtual array of parallel processors, and mapping the virtual array of parallel processors to a physical array of parallel processors.
