In July 2020, EPEEC announced the development of OmpSs-2@OpenACC [1] by the BSC Accelerators and Communication team using ZPIC [2], 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.

The National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with the Argonne Leadership Computing Facility (ALCF) at Argonne National Laboratory, has signed a contract with Codeplay Software to enhance the LLVM SYCL GPU compiler capabilities for NVIDIA A100 GPUs.
This collaboration will help NERSC and ALCF users, along with the high-performance computing community in general, produce high-performance applications that are portable across compute architectures from multiple vendors.
