0upvotes

Use this skill when the user is running DOCA Perftest (doca_perftest), the RDMA benchmark that measures bandwidth, message rate and latency for RDMA verbs, point-to-point or across a cluster, with an optional DOCA Verbs backend (-r dv) or GPUNetIO engine (--engine gpunetio). Trigger even when the user does not say "DOCA Perftest" — implicit phrasings include "how do I benchmark RDMA write bandwidth with DOCA", "run ib_write_bw but across 8 nodes", "perftest says the device is busy", "my latency numbers differ between client and server", "launch the server over SSH", or "run an all-to-all RDMA test from a JSON scenario". Refuse and route elsewhere for DOCA install (doca-setup), DOCA Bench (doca-bench), and application-level throughput.

# DOCA Perftest

## When to load this skill

Load this skill when the user wants to — or the agent needs to — run
`doca_perftest` on a host with DOCA installed. Concretely:

- Measuring RDMA bandwidth, message rate, or latency between two hosts
  (point-to-point) with a verb such as write / read / send.
- Running the same benchmark across many nodes — JSON scenario or
  `--traffic_pattern` (pair-wise, all-to-all), orchestrated over
  OpenMPI / passwordless SSH.
- Comparing the IBV and DOCA Verbs backends (`-r ibv` vs `-r dv`) or
  driving the GPUNetIO engine (`--engine gpunetio`).
