multi-level, parallel, polyhedral, heterogeneous platforms
Tremendous progress in automatic parallelization brought advanced transformations for data parallelism and locality targeting chip multicore processors, but a platform as a whole is seldom considered. Emerging heterogeneous platforms composed of loosely coupled components such as CPUs, GPUs and specialized IP cores, offer unprecedented parallelization opportunities. We propose a hierarchical, multi-level program model, called HiPRDG, for more efficient mapping on heterogeneous platforms, and describe a method for its derivation from the standard program model in the polyhedral framework. In this paper, we show how a HiPRDG can be used to derive a two-level process network model of a streaming application, which is capable of exploiting task, data, and pipeline parallelism on a heterogeneous platform with a GPU accelerator, and present performance results.
