The University of Bristol’s High Performance Computing (HPC) Research Group has established an Intel oneAPI Center of Excellence, building on its history of close collaboration with Intel on performance portability and advanced computer architectures. The Center is developing best practices for achieving performance portability at exascale using oneAPI open cross-architecture programming and the Khronos Group’s SYCL abstraction layer for cross-platform heterogeneous programming, ensuring that scientific codes can achieve high performance on massive heterogeneous supercomputing systems.
