Use this skill when the user is building, running, or interpreting the doca/tools/gpunetio_ib_write_bw client+server benchmark — a CUDA kernel on the client posts RDMA WRITE work requests through the doca-gpunetio device-side surface to measure sustained GPU-driven WRITE bandwidth on a GPU+IB-device pair. Trigger even when the user does not explicitly mention "doca-gpunetio-ib-write-bw" or "GPUNetIO" — typical implicit phrasings include "measure WRITE BW when the GPU posts the WRs…
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 GPUNetIO ib_write_bw ## Examples - **"What sustained RDMA-WRITE bandwidth can GPUNetIO deliver on this GPU-NIC pair?"** — this is in scope. Stay on `gpunetio_ib_write_bw`; do not retune a live GPI app here. - **"Where is the bottleneck — GPU occupancy, NIC issue rate, or link saturation?"** — decompose throughput before changing the CUDA kernel. ## Instructions Follow Loading order below. Open the tasks companion for configure / run / debug. Open the capabilities companion for GPU-NIC pairing and observability. Do not open every companion file. **Where to start:** This is a tool skill for the GPUNetIO- flavored `ib_write_bw` benchmark shipped under `doca/tools/gpunetio_ib_write_bw/` (a client + server pair, built from source against the installed DOCA via `meson`). It measures sustained RDMA WRITE bandwidth when the WRs are posted **from a CUDA kernel through the doca-gpunetio device-side surface**, with the GPU on the data path. Open the tasks companion and start at `## configure` for the GPU-NIC pairing precondition and the build pattern; jump to `## run` for the smoke-before-bulk flow. Open the capabilities companion when the question …

How to install
mdr add nvidia/skills/doca-gpunetio-ib-write-bw@sha256:2b0a82fe7647e1d9The 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.
