MetaFork: A Framework for Concurrency Platforms Targeting Multicores

We present MetaFork, a metalanguage for multithreaded algorithms based on the fork-join concurrency model and targeting multicore architectures. MetaFork is implemented as a source-to-source compilation framework allowing automatic translation of programs from one concurrency platform to another. The current version of this framework supports CilkPlus and OpenMP. We evaluate the benefits of the MetaFork framework through a series of experiments, such as narrowing performance bottlenecks in multithreaded programs. Our experiments show also that, if a native program, written either in CilkPlus or OpenMP, has little parallelism overhead, then the same property holds for its OpenMP or CilkPlus counterpart translated by MetaFork.
