## Health v2 (maintenance only)
Score: 85/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 97, release rhythm 62, longevity 100
- inputs: {"age_days": 3611, "days_push": 20, "days_rel": 94, "gap_med": 97.0, "n_releases_24m": 7}
- flags: no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of C-based performance micro-benchmark tools for InfiniBand and RoCE networks, built on the ibverbs API. It measures bandwidth and latency for Send, RDMA Read/Write/Atomic, and raw Ethernet operations.

## Use cases
- measure RDMA bandwidth between two hosts
- benchmark InfiniBand network latency
- tune HPC cluster network performance
- test RDMA read and write throughput
- validate RoCE hardware after deployment
- benchmark raw Ethernet performance with MOFED2

## When to choose
- you need low-level RDMA/InfiniBand bandwidth or latency micro-benchmarks
- you are tuning or validating high-performance network hardware on Linux
- you want standard tools compatible with OFED/MOFED ecosystems

## When to avoid
- you need TCP/IP or general Ethernet benchmarking without RDMA hardware
- you want a GUI or automated continuous benchmarking suite
- you are on a non-Linux platform

## Facets
- artifact type: cli-tool
- maturity: active
- function: benchmarking, networking, developer-tools
- domain: networking, performance, developer-tools, hardware
- platform: cli, cpp
- tags: infiniband, rdma, verbs, micro-benchmark, bandwidth, latency, hpc, gpudirect, linux
