ABSTRACT:
Deterministic and scale- free programming models built on a task abstraction offer a viable path to ubiquitous parallelism. However, it remains hard to reconcile these attributes with pipeline parallelism, where the number of pipeline stages is typically hard-coded in the program and defines the degree of parallelism. This paper introduces hyperqueues, a programming abstraction that enables deterministic and scale-free pipeline parallel programs. Hyperqueues extend the concept of Cilk++'s hyperobjects to provide thread-local views on a shared data structure. While hyperobjects are organized around private local views, hyperqueues require shared concurrent views on the underlying data structure. We define the semantics of hyperqueues and describe their implementation in a work-stealing scheduler. We demonstrate scalable performance on pipeline parallel PARSEC benchmarks and find that hyperqueues provide comparable or better performance than implementations that are highly tuned to the number of available processing cores using POSIX threads and Intels Threading Building Blocks.
