NVIDIA publishes gds-diag diagnostic tool for GPUDirect Storage in Magnum IO repo
gds-diag is an open-source command-line utility in the NVIDIA Magnum IO GitHub repository that assesses GPUDirect Storage (GDS) environments, runs grouped end-to-end and targeted checks (pre-install, post-install, container, mount), and suggests mitigations. An optional agent skill adds a natural-language interface that orchestrates multi-step diagnostics and applies model-guided reasoning via coding assistants (examples mention Claude and Codex).
