OpenMP is a de facto standard interface of the shared address space parallel programming model. Recently, there have been many attempts to use it as a programming environment for embedded MultiProcessor Systems-On-Chip (MPSoCs). This is due both to the ease of specifying parallel execution within a sequential code with OpenMP directives, and to the lack of a standard parallel programming method on MPSoCs. However, MPSoC platforms for embedded applications often feature non-uniform, explicitly managed memory hierarchies with no hardware cache coherency as well as heterogeneous cores with heterogeneous run-time systems. In this paper we present an optimized implementation of the compiler and runtime support infrastructure for OpenMP programming for a non-cache-coherent distributed memory MPSoC with explicitly managed scratchpad memories (SPM). The proposed framework …
