Kokkos is a programming model developed at Sandia National Laboratories for enabling application developers to achieve performance portability for C++ codes. It is now the primary programming model at Sandia to port production-level applications to modern architectures, including GPUs. We'll discuss the core abstractions of Kokkos for parallel execution as well as data management, and how they are used to provide a critically important set of capabilities for the efficient implementation of a wide range of HPC algorithms. We'll present performance evaluations on a range of platforms to demonstrate the state of the art of performance portability. This will include data from Intel KNL-based systems as well as IBM Power8 with NVIDIA NVLink-connected NVIDIA Tesla P100 GPUs. We'll also provide an overview of how Kokkos fits into the larger exascale project at the Department of Energy, and how it is used to advance the development of parallel programming support in the C++ language standa  Back
