  • Single instruction multiple data (SIMD) code generation for parallel loops using versioning and scheduling
    Patent number: 8341615
    Abstract: Embodiments of the present invention address deficiencies of the art in respect to loop parallelization for a target architecture implementing a shared memory model and provide a novel and non-obvious method, system and computer program product for SIMD code generation for parallel loops using versioning and scheduling. In an embodiment of the invention, within a code compilation data processing system a parallel SIMD loop code generation method can include identifying a loop in a representation of source code as a parallel loop candidate, either through a user directive or through auto-parallelization.
    Type: Grant

  • Generating optimized SIMD code in the presence of data dependences
    Patent number: 8037464
    Abstract: A method for generating code, including identifying at least one portion of source code that is simdizable and has a dependence, analyzing the dependence for characteristics, based upon the characteristics, selecting a transformation from a predefined group of transformations, applying the transformation to the at least one portion to generate SIMD code for the at least one portion.
