The complexity of parallel programming greatly limits the effectiveness of chip-multiprocessors (CMPs). This paper presents the case for task superscalar pipelines, an abstraction of traditional out-of-order superscalar pipelines, that orchestrates an entire chip-multiprocessor in the same degree out-of-order pipelines manage functional units. Task superscalar leverages an emerging class of task-based dataflow programming models to relieve programmers fromexplicitlymanaging parallel resources. We posit that task superscalar overcome many of the limitations of instruction-level out-of-order pipelines, and provide a scalable interface for CMPs.
