  1. NVIDIA Adds an AI Agent Skill to GPUDirect Storage Diagnostics

    NVIDIA introduced an optional agent skill for gds-diag, an open-source command-line utility that checks GPUDirect Storage environments, identifies problems, and suggests improvements. The skill adds natural-language routing, multi-step diagnostic orchestration, and model-guided interpretation of results, while the underlying tool provides deterministic checks and JSON output.

  2. 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.

  3. FADU Moves File Operations Into SSD Firmware

    FADU unveiled its File-Semantic SSD (FS-SSD) at the 2026 OCP Global Summit, moving path lookup, access checks, and file-to-flash mapping into the drive while carrying NFSv3 operations in standard NVMe commands. In FADU's preliminary vendor test, a Gen6 FC6161 drive in a PCIe 5.0 host maintained about 460,000 remote file operations per second as the server was reduced from what FADU labels as 16 cores to one. The company expects PCIe 6.0 Gen6-host results by Q1 2027. The current software lacks features including ACLs, and FADU has not submitted a file-semantic command set to NVM Express or OCP Storage.
