<pubDate>Mon, 30 Mar 2026 08:25:49 -0400</pubDate>
<guid>https://huatuo.tech/events/2026-03-30-release-v220/</guid>
<description><p>Following a period of development and testing, the v2.2.0 release is now available. This provides a more stable and robust foundation for large-scale production environments.</p>
<h3 id="key-features">Key Features</h3>
<ul>
<li><strong>Hardware</strong>: Hardware fault detection has been added for AI and general-purpose computing scenarios. This includes support for RDMA PFC congestion detection.</li>
<li><strong>Multi-Cloud</strong>: Native adapters have been implemented for major cloud platforms, including Alibaba Cloud, Google Cloud, and AWS.</li>
<li><strong>MetaX</strong>: GPU hardware fault detection capabilities were contributed to the community by MetaX,</li>
<li><strong>Kubernetes</strong>: Support for additional cgroup driver types has been added, along with an automated detection mechanism.</li>
<li><strong>IOtracing</strong>: The <code>iotracing</code> tool has been open-sourced. It supports rapid execution and automated tracing from the command line, addressing intermittent I/O performance issues.</li>
<li><strong>Configuration</strong>: All configuration options have been standardized. This significantly reduces the complexity.</li>
<li><strong>Testing</strong>: The test suite has been expanded to unit, integration, and end-to-end tests.</li>
</ul>
<h3 id="documentation">Documentation</h3>
<p>The documentation structure for version 2.2.0 has been revised and expanded. These improvements are intended to accelerate the onboarding process and enable users to more fully leverage HUATUO.</p></description>

<h3 id="沐曦股份开源生态介绍">沐曦股份开源生态介绍</h3>
<p>沐曦股份坚持“自主创新与开放兼容”双轨战略,以自研MXMACA软件栈为核心,构建硬件与应用的桥梁,并承载开源核心使命。该栈于2025年2月正式开源,致力于打造开放的GPU编程接口标准,大幅降低开发门槛,有效破解跨平台兼容难题,驱动AI算力生态协同创新。</p>
<p>技术落地方面,沐曦深度融入全球开源社区:成为vLLM官方支持的中国GPU厂商,与红帽联合推出MXAIE优化方案,实现对龙蜥、OpenCloudOS、麒麟、RHEL等主流OS的适配,并深度参与vLLM、PaddlePaddle、OpenXLA、BigDL等上游项目,确保主流框架和大模型的“Day 0”级支持。截至2025年底,已发布30余个开源项目,MXMACA用户超25万,支持超4500个模型“即插即用”。通过技术赛事、高校推广及算力服务平台建设,沐曦正加速构建覆盖开发者、产业与科研的开放生态,目标是铸就AI时代的“Android式”开放共赢算力基础。</p>
<h3 id="huatuo-华佗">HUATUO 华佗</h3>
<p>HUATUO(华佗)是由滴滴开源并依托 CCF (中国计算机学会)孵化的操作系统深度观测项目,专注为云原生通用计算,AI 计算,云服务,基础服务等提供操作系统内核级深度观测能力,<a href="https://mp.weixin.qq.com/s/aFKdCiXIHKFKBFdSf58buQ">《滴滴操作系统可观测 HUATUO 项目正式入驻 CCF》</a>。</p>

</p>
<p>HUATUO 通过调用 MetaX libmxsml 获取实时的 GPU 数据,在开启了 MetaX GPU 监控后,可以在华佗中查询到 GPU 相关的数据,如:</p>
<div class="highlight"><pre tabindex="0" style="color:#d8dee9;background-color:#2e3440;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span>1. GPU 基础信息:如 GPU 型号、GPU 标识、驱动版本等
</span></span><span style="display:flex;"><span>2. GPU 状态:如 GPU 功耗、温度、利用率、时钟频率等
</span></span><span style="display:flex;"><span>3. GPU 通信:如 PCIe 速度、带宽,MetaXLink 速度、带宽等
</span></span></code></pre></div><p>这些数据可以帮助我们更加清晰地定位生产环境中的各种问题。有关指标的详细说明,请见后续的&quot;指标介绍&quot;章节。如果想要启用 MetaX GPU 的监控,需要将以下内容挂载到容器中的对应位置:</p>
<div class="highlight"><pre tabindex="0" style="color:#d8dee9;background-color:#2e3440;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-bash" data-lang="bash"><span style="display:flex;"><span>1. /opt/maca:/opt/maca

</span></span><span style="display:flex;"><span>3. /dev/dri:/dev/dri
</span></span></code></pre></div><p>Docker 容器的启动命令为:</p>
<div class="highlight"><pre tabindex="0" style="color:#d8dee9;background-color:#2e3440;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-shell" data-lang="shell"><span style="display:flex;"><span>docker run --privileged --cgroupns<span style="color:#81a1c1">=</span>host --network<span style="color:#81a1c1">=</span>host <span style="color:#ebcb8b">\

</span></span></span><span style="display:flex;"><span><span style="color:#ebcb8b"></span> huatuo/huatuo-bamai:latest
</span></span></code></pre></div><p>如果是在 K8s 中使用,则创建相应的 PV 与 PVC 即可。在容器启动完毕后,访问其服务地址的 <code>/metrics</code> endpoint,如果输出中包含带有 metax 字样的指标,则成功采集了 GPU 数据。</p></description>

<p>滴滴基础产品事业部高级软件开发工程师涂曾兵分享了《HUATUO在滴滴的规模化应用实践和开源社区建设》。在云原生与AI技术快速发展的今天,操作系统级可观测性成为保障复杂系统稳定性的关键。滴滴开源与CCF(中国计算机学会)重点孵化的HUATUO项目基于eBPF技术实现低损耗、零侵扰的内核数据采集,覆盖TCP/IP协议栈、CPU调度、内存管理等核心模块,并构建异常事件驱动诊断与全自动化追踪(AutoTracing)两大核心引擎,能够自动捕获softlockup、oom、网络延迟等关键事件,精准定位云原生场景下的偶发与突发故障。</p>
</li>
<li>
<p>在持续性能剖析层面,HUATUO突破传统工具局限,提供多语言、全栈、可回溯的剖析能力,结合Grafana等开源生态输出可视化分析,助力企业从“被动救火”转向“主动预防”。目前该项目已在多家企业落地,覆盖出行、金融等多类场景,推动可观测技术领域操作系统基础设施向标准化、自动化、智能化演进。</p>

<li>查看异常事件 (Events, AutoTracing):HUATUO 会将采集到的内核异常事件信息在 ES (已关闭),和本地目录 <code>huatuo-local</code> 分别存储。注意:通常该路径下没有任何文件(正常状态的系统不会触发事件采集),你可以通过构造异常场景或者修改配置文件阈值产生事件。</li>

<h4 id="22-docker-compose-启动">2.2 Docker Compose 启动</h4>
<p>通过 docker compose,可以快速地在本地搭建部署一套完整的环境。该命令拉取最新镜像,启动 <a href="https://www.elastic.co">elasticsearch</a>, <a href="https://prometheus.io">prometheus</a>, <a href="https://grafana.com">grafana</a>,huatuo-bamai 等组件。命令执行成功后,打开浏览器访问 <a href="http://localhost:3000">http://localhost:3000</a> 即可浏览监控大盘(grafana 默认管理员账户:admin 密码:admin; 系统正常状态不会触发 Events, AutoTracing)。</p></description>

<description><p>HUATUO is a cloud-native operating system observability project open-sourced by DIDI and incubated under the CCF. It delivers kernel-level observability for general-purpose cloud-native computing, AI computing, and bare-metal infrastructure services. By integrating Linux kernel dynamic tracing like kprobe, tracepoint, ftrace, and eBPF, HUATUO provides kernel-wide insights: finer-grained metrics, automatic context capture from kernel runtime, and intelligent tracing.</p></description>
