Limits of Task-based Parallelism in Irregular Applications

By Barbara Kreaseck, Dean Tullsen and Brad Calder


Traditional parallel compilers do not effectively parallelize irregular applications because they contain little loop-level parallelism. We explore Speculative Task Parallelism (STP), where tasks are full procedures and entire natural loops. Through profiling and compiler analysis, we find tasks that are speculatively memory- and control-independent of their neighboring code. Via speculative futures, these tasks may be executed in parallel with preceding code when there is a high probability of independence
