We 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 compiler, runtime, and programming model to support OmpSs-2 + OpenACC programming. To validate our proposal we port ZPIC, a plasma simulator application, to leverage our hybrid OmpSs-2 + OpenACC implementation. We compare our approach against OpenACC versions of ZPIC in terms of programmability and performance on a multi-GPU HPC system. We show that our approach manages to outperform manually programmed versions, including multi-GPU execution, while removing significant burden from the application’s developer.
