In July 2020, EPEEC announced the development of OmpSs-2@OpenACC  by the BSC Accelerators and Communication team using ZPIC , developed by INESC-ID, as our driving application. They have continued to improve the interoperation and co-design mechanisms by the addition of an affinity scheduler to minimize device-to-device communication. They currently outperform an equivalent multi-GPU OpenMP+OpenACC version of ZPIC without the programmer needing to manually manage asynchronous kernels or scheduling kernels to specific devices.
The Khronos Group today formally launched SYCL 2020, the parallel programming framework based on IS0 standard C++ that has been gaining traction in HPC and will, for example, be supported on the forthcoming exascale supercomputer Aurora (ANL) and pre-exascale system Perlmutter (NERSC/LBNL). SYCL 2020 builds on the functionality of SYCL 1.2.1. adding 40-plus new features and introduces a new naming convention based on the year. SYCL 2020 is based on C++17.
