pykokkos-base provides the ability to pass Kokkos data structures (View, DynRankView -- which are similar to NumPy's ndarray) between Python and C++ and interoperability with NumPy and CuPy arrays.
Kokkos implements a programming model in C++ for writing performance portable applications targeting all major HPC platforms. It provides abstractions for both parallel execution of code and data management with a variety of backends including, but not limited to: CUDA, HIP, OpenMP, HPX, and Pthreads, with backends for OpenMPTarget and SYCL currently under development.
Making these bindings available was a critical step in the progress toward writing Kokkos in native Python via pykokkos, which is currently available for Linux + Python 3.8 + GCC 7.5 + CUDA 10.2 toolchains.
