Programming model and software system for exploiting parallelism in irregular programs

Systems and methods for parallelizing applications that operate on irregular data structures. In an embodiment, the methods and systems enable programmers to use set iterators to express algorithms containing amorphous data parallelism. Parallelization can be achieved by speculatively executing multiple iterations of the iterator in parallel. Conflicts between speculatively executing iterations can be detected and handled using information in class libraries.Board of Regents, University of Texas Syste
