摘要： 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. The method also can include selecting a trip count condition responsive to a scheduling policy set for the code compilation data processing system and also on a minimal simdizable threshold, determining a trip count and an alignment constraint for the selected loop, and generating a version of a parallel loop in the source code according to the alignment constraint and a comparison of the trip count to the trip count condition.
