FFI C++ Interface: Availability of Device-CPU Data Transfer APIs

[dasikuzi2]

Does the FFI C++ interface provide APIs for data communication between device and CPU, such as device-to-CPU or CPU-to-device transfers?

Thanks @dasikuzi2 for the question. We intentionally minimize the overall dependency as a result do not introduce device cpu transfer apis atm. Users can still run such transfer with existing APIs like cudaMemcpy
