OmpSs-2 and OpenACC Interoperation
DescriptionWe propose an interoperation mechanism to enable novel composability across pragma-based programming models. We study and propose a clear separation of duties and implement our approach by augmenting the OmpSs-2 programming model, compiler and runtime system to support OmpSs-2 + OpenACC programming. To validate our proposal we port ZPIC, a kinetic plasma simulator, to leverage our hybrid OmpSs-2 + OpenACC implementation. We compare our approach against OpenACC versions of ZPIC in terms of on a multi-GPU HPC system. We show that our approach manages to provide automatic asynchronous and multi-GPU execution, removing significant burden from the application’s developer, while also being able to outperform manually programmed versions, thanks to a better utilization of the hardware.
