【温馨提示：本篇文章涉及较多代码，请移步至wx公号星融元Asterfusion，发送关键词“分布式”获取完整版及Q&A】

随着AI、大模型的快速发展，传统的集中式计算已无法应对激增的数据处理需求，而分布式计算是指将一个计算任务分解成多个子任务，由多个计算节点并行地进行计算，并将结果汇总得到最终结果的计算方式，能够更高效、更稳定、更灵活地处理大规模数据和复杂计算任务，在各行各业中得到了广泛的应用。

那如何从零到一搭建分布式计算的环境呢？本文将从硬件选型，到服务器侧的基础配置、GPU驱动安装和集合通讯库配置，以及无损以太网的启用，直至大模型导入和训练测试，带您跑通搭建分布式计算环境的全流程。

硬件准备

GPU服务器选型

GPU拥有大量的计算核心，可以同时处理多个数据任务，是构成智算中心的关键硬件。

从智算中心方案的整体设计层面来看：GPU服务器集群和存储服务器集群分别通过计算网络（Scale-out网络）和存储网络连接。另外两张管理网中，业务管理网用于GPU服务器互联，进行AIOS管理面通信，带外管理则连接整个智算中心的所有设备，用于运维接入管理。

明确了智算中心的整体设计后，我们将对比通用计算服务器与GPU服务器的内部硬件连接拓扑图，来具体了解GPU服务器的选型逻辑：

图2是一台通用计算服务器内部的硬件连接拓扑，这台服务器的核心是两块AMD的EPYC CPU，根据IO Chiplet扩展出了若干接口，辅助CPU充分释放通用计算能力。

图3是一台GPU服务器内部的硬件连接拓扑，这台服务器配备了8块A100 GPU，8张用于计算通信的RDMA网卡，以及2张用于存储通信的RDMA网卡，所有的IO组件设计，都是为了让这8块GPU充分释放算力。

通过上面两张硬件连接拓扑图可以看到，通用服务器和GPU服务器从基本的硬件构造上就有着非常大的差异，一个是围绕通用CPU来构建，另一个是围绕着GPU来构建的。因此，在硬件选型阶段，就需要注意差别，通常来讲通用服务器是没有办法复用改造成一台高性能的GPU服务器，PCIe接口数量、服务器空间、散热设计、电源等方面都不能满足要求。

当通过计算任务确定算力需求，进而确定了所需要的GPU型号和数量之后，我们也就可以再继续规划整个GPU集群的组网了。

由于资源限制，本次实验验证中，使用三台通用服务器稍加改造进行后续的并行训练和推理测试。

计算节点的硬件配置如下：

CPU：Intel(R) Xeon(R) CPU E5-2678 v3 @ 2.50GHz * 2

GPU：NVIDIA GeForce RTX 4060 Ti 16G * 1

内存：128G

存储：10T HDD * 2

网卡：MGMT、CX5

其他部分：

散热：GPU为全高尺寸，但服务器只有2U，所以只能拆掉上盖板;

电源：通用服务器通常没有预留足够的供电接口，因此需要使用外置电源对GPU进行额外供电；

电源选择的是Great Wall 额定650W X6，功率上可以同时满足3块GPU（RTX4060Ti需要外接150W的供电）的供电要求，并且支持3个8pin接口，用来分别连接三块GPU。

高性能计算网选型

智算中心的管理网相较于传统的通用计算数据中心来说，没有太大差异。比较特殊的就是Scale-out计算网络和存储网络，这两张网络承载的业务流量决定了交换机设备的选型需求：支持RDMA、低时延、高吞吐。

如下图所示，在组网连接方面也有所不同，这里会通过将GPU分组（图中#L0～7一组，#L8～15一组），组成只有一跳的高带宽互联域（HB域），并通过针对智算场景优化的Rail交换机连接，实现了高效的数据传输和计算协同。

这次实验验证中，计算网的交换机选用星融元Asterfusion®️ CX-N系列超低时延交换机，具体型号为CX308P-48Y-N。

型号	业务接口	交换容量
CX864E-N	64 x 800GE OSFP，2 x 10GE SFP+	102.4Tbps
CX732Q-N	32 x 400GE QSFP-DD, 2 x 10GE SFP+	25.6Tbps
CX664D-N	64 x 200GE QSFP56, 2 x 10GE SFP+	25.6Tbps
CX564P-N	64 x 100GE QSFP28, 2 x 10GE SFP+	12.8Tbps
CX532P-N	32 x 100GE QSFP28, 2 x 10GE SFP+	6.4Tbps
CX308P-48Y-N	48 x 25GE SFP28, 8 x 100GE QSFP28	4.0Tbps

表1：具体型号规格示意

提升大模型训练效率

CX-N数据中心交换机的单机转发时延（400ns）低至业界平均水平的1/4~1/5，将网络时延在AI/ML应用端到端时延中的占比降至最低，同时多维度的高可靠设计确保网络在任何时候都不中断，帮助大模型的训练大幅度降低训练时间、提升整体效率。

全系列标配RoCEv2能力

区别于传统厂家多等级License权限管理方式，CX-N数据中心交换机所有应用场景License权限一致，全系列标配RoCEv2能力，提供PFC、ECN、Easy RoCE等一系列面向生产环境的增强网络特性，用户无须为此类高级特性额外付出网络建设成本，帮助用户获得更高的ROI。

开放、中立的AI/ML网络

星融元AI/ML网络解决方案的开放性确保用户能够重用已有的系统（K8s、Prometheus等）对网络进行管理，无需重复投入；星融元以“中立的网络供应商参与AI生态”的理念为用户提供专业的网络方案，帮助用户规避“全栈方案锁定”的风险。

最终，实验环节的组网拓扑和基础配置如下所示。

软件准备

以上，我们已经完成了硬件选型，接下来我们将进行软件层面的配置：部署 RoCEv2 交换机、配置GPU 服务器、安装 GPU 驱动和集合通讯库。

RoCEv2交换机

本次并行训练的环境中设备数量较少，组网相对简单：

1. 将CX5网卡的25GE业务接口连接到CX308P；

2. 在交换机上一键启用全局RoCE的无损配置；

3. 将三个25G业务口划分到一个VLAN下组成一个二层网络；

如前文提到，CX-N数据中心交换机全系列标配RoCEv2能力，配合星融元AsterNOS网络操作系统，只需要两行命令行便可配置所有必要的QoS规则和参数，具体命令行如下：

noone@MacBook-Air ~ % ssh admin@10.230.1.17

安装MLNX网卡驱动

下文以CentOS7为例，详细介绍了Mellanox网卡MLNX_OFED的驱动安装和固件升级方法。

本次下载的驱动版本为：MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64.tgz。

[root@server3 ~]# tar –zxvf MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64.tgz
[root@server3 ~]# cd MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64
查看当前系统的内核版本
[root@server3 MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64]# uname -r
3.10.0-957.el7.x86_64
查看当前驱动所支持的内核版本
[root@server3 MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64]# cat .supported_kernels 
3.10.0-957.el7.x86_64 
注：由以上可知下载的默认驱动支持当前的内核版本
如果当前内核与支持内核不匹配，手动编译适合内核的驱动，在编译之前首先安装gcc编译环境和kernel开发包
[root@server3 MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64]#yum  install gcc gcc-c++
libstdc++-devel kernel-default-devel 
添加针对当前内核版本的驱动
[root@server3 MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64]#./mlnx_add_kernel_support.sh -m /root/MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64  -v
注：完成后生成的驱动文件在/tmp目录下
[root@server3 MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64]# ls -l /tmp/MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64-ext.tgz
-rw-r--r-- 1 root root 282193833 Dec 23 09:49 /tmp/MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64-ext.tgz
安装驱动
[root@server3 tmp]# tar xzvf MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64-ext.tgz
[root@server3 tmp]# cd MLNX_OFED_LINUX-4.7-3.2.9.0-rhel7.6-x86_64-ext
[root@server3 tmp]# ./mlnxofedinstall
最后启动openibd服务
[root@server3 ~]#/etc/init.d/openibd start
[root@server3 ~]#chkconfig openibd on

结果详解

- size (B)：操作处理的数据的大小，以字节为单位；

- count (elements)：操作处理的元素的数量；

- type：元素的数据类型；

- redop：使用的归约操作；

- root：对于某些操作（如 reduce 和 broadcast），这列指定了根节点的编号，值是 -1 表示这个操作没有根节点（all-reduce 操作涉及到所有的节点）；

- time (us)：操作的执行时间，以微秒为单位；

- algbw (GB/s)：算法带宽，以每秒吉字节（GB/s）为单位；

- busbw (GB/s)：总线带宽，以每秒吉字节（GB/s）为单位；

- wrong：错误的数量，如果这个值不是 0，那可能表示有一些错误发生。

在这个例子中，你可以看到，当处理的数据量增大时，算法带宽和总线带宽都有所提高，这可能表示 NCCL 能够有效地利用大量的数据。

查看结果时，需要关注如下几点：

1. 数据量增加时，带宽是否会下降（下降明显不符合预期）；

2. 更关注带宽的峰值，每次算到的带宽峰值，可以只关注 in 或者 out；

3. 平均值，在数据量递增的情况下，可能无法体现最终的结果；

4. 请确保数据量足够大，可以压到带宽上限（通过调整 b、e 或者 n 选项）。

获取LLaMA-Factory源码包

下载训练时所需的预训练模型和数据集

根据当前GPU服务器所配置的GPU硬件规格，选择适合的训练方法、模型和数据集。

GPU型号：NVIDIA GeForce RTX 4060 Ti 16GB

预训练模型：Qwen/Qwen1.5-0.5B-Chat

数据集：identity、alpaca_zh_demo

# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install
git clone https://hf-mirror.com/Qwen/Qwen1.5-0.5B-Chat
# If you want to clone without large files - just their pointers
GIT_LFS_SKIP_SMUDGE=1 git clone https://hf-mirror.com/Qwen/Qwen1.5-0.5B-Chat

因为网络问题通过命令行很难直接下载，这里使用huggingface的国内镜像站拉取预训练模型数据，并使用“GIT_LFS_SKIP_SMUDGE=1”变量跳过大文件，随后手工下载后再上传。

如果觉得麻烦，也可以安装使用huggingface的命令行工具，下载预训练模型和数据集。同样地，安装完成后，需要配置一些环境变量（使用镜像站hf-mirror.com）来解决网络问题。

1. 安装依赖
[root@server3 LLaMA-Factory-0.8.3]# pip3 install -U huggingface_hub
2. 设置环境变量
[root@server3 LLaMA-Factory-0.8.3]# export HF_ENDPOINT=https://hf-mirror.com
可以写入 ~/.bashrc 永久生效。
3. 确认环境变量生效
[root@server3 LLaMA-Factory-0.8.3]# huggingface-cli env

使用准备好的模型与数据集，在单机上进行训练测试

LLaMA-Factory支持通过WebUI微调大语言模型。在完成安装后，我们可以使用WebUI进行快速调测验证，没问题后可使用命令行工具进行多机分布式训练。

注册模型

打开一个新的terminal

[root@server3 AIGC]# cd LLaMA-Factory-0.8.3/asterun/
[root@server3 asterun]# ll

drwxr-xr-x 3 root root  18 9月  13 10:28 saves
创建模型的Modelfile文件
[root@server3 asterun]# touch qwen_full_sft_ds2.ollama.Modelfile
[root@server3 asterun]# vim qwen_full_sft_ds2.ollama.Modelfile 
[root@server3 asterun]# cat qwen_full_sft_ds2.ollama.Modelfile
