HAMR
HAMR is a library defining an accelerator technology agnostic memory model that bridges between accelerator technologies (CUDA, HIP, ROCm, OpenMP, Kokos, etc) and traditional CPUs in heterogeneous computing environments. HAMR is light weight and implemented in modern C++. HAMR includes Python integration that enables zero-copy data transfer between C++ and Python technogies such as Numba and Cupy.

Source Code
The source code can be obtained at the HAMR github repository.
Documentation
The HAMR User's Guide documents compiling and use of HAMR and contains simple examples.
The HAMR Doxygen site documents the APIs. Most users will want to start with the hamr::buffer, a container that has capabilities similar to std::vector and can provide access to data in different accelerator execution environments.
