doca-gpi SKILL.md skillA
doca-gpi from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nvidia/skills/doca-gpi@git:20261014.bbb601aPins git:20261014.bbb601a in mdr.lock. Pin the fingerprint instead.

Use this skill for hands-on DOCA GPI programming — wiring a GPU-Packet-Initiator context so a CUDA kernel drives RDMA queues directly from GPU memory without host CPU mediation. Covers picking GPI vs doca-gpunetio, the doca_gpi / domain / channel object model, the GPU-side handle handoff (doca_gpu_gpi_channel*), attaching GPU memory to a GPI domain, the domain and channel attribute objects, and debugging DOCA_ERROR_* from doca_gpi_* calls. Trigger even when the user does not explicitly mention…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DOCA GPI ## Examples - **"CUDA kernel needs to post RDMA from GPU memory."** — this is in scope. Use GPI domain / channel, not the GPUNetIO send/recv surface. - **"How do I hand a GPU handle to my CUDA kernel?"** — use `doca_gpu_gpi_channel*`. Do not route this to DPA-side RDMI. ## Instructions Follow Loading order below. Open the tasks companion for configure / modify / debug. Open the capabilities companion for GPI vs GPUNetIO vs RDMI. Do not open every companion file. **Where to start:** This skill assumes DOCA is already installed and the user is doing **hands-on GPI work** on a host that has both a BlueField / ConnectX device and an NVIDIA GPU reachable over PCIe. Open the tasks companion if the user wants to *do* something (install / configure / build / modify / run / test / debug / use); open the capabilities companion when the question is *what can GPI express on this version* — the domain + channel object model, the GPU-side handle handoff, the relationship to doca-gpunetio and doca-verbs, the attribute objects, and the safety overlay. If the user has not installed DOCA yet, route to `doca-setup/SKILL.md` first. ## Example questions this skill answers well …

How to install
mdr add nvidia/skills/doca-gpi@sha256:0bc458a786ce3928The line at the top of this page pins the label git:20261014.bbb601a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
