   NVIDIA tutorial: reading data into GPU memory with KvikIO and GPUDirect Storage

   NVIDIA published a technical tutorial showing how to use the KvikIO Python API to read a file directly into GPU memory through GPUDirect Storage (GDS). The walkthrough configures storage I/O, allocates a 1 GiB CuPy buffer, performs the read via KvikIO's cuFile interface, and then uses cuFile level-three statistics inspected with gds_stats to check whether the nvidia-fs accelerated path or the CPU-staged POSIX path handled the transfer. NVIDIA stresses that KvikIO and cuFile make separate path decisions, so reaching the cuFile API does not by itself confirm the accelerated GDS path was activated. The post also notes KvikIO is part of the CUDA-X libraries for data science and is used by libraries such as cuDF.
