那怎么从零到一建立分布式核算的环境呢？本文将从硬件选型，蓝灯立方到服务器侧的根底装备、蓝灯立方GPU驱动装置和调集通讯库装备，以及无损以太网的启用，直至大模型导入和练习测验，带您跑通建立分布式核算环境的全流程。在完结装置后，暨水咱们能够运用WebUI进行快速调测验证，没问题后可运用命令行东西进行多机分布式练习。

因为资源约束，公益本次试验验证中，运用三台通用服务器稍加改造进行后续的并行练习和推理测验。-NCCL操作相关装备--o,--op指定那种操作为reduce，基金仅适用于Allreduce、Reduce或ReduceScatter等减缩操作。图1：成立智算中心计划的概要规划拓扑清晰了智算中心的全体规划后，成立咱们将比照通用核算服务器与GPU服务器的内部硬件衔接拓扑图，来详细了解GPU服务器的选型逻辑：图2：通用核算服务器内部的硬件衔接拓扑图3：GPU服务器内部的硬件衔接拓扑图2是一台通用核算服务器内部的硬件衔接拓扑，这台服务器的中心是两块AMD的EPYCCPU，依据IOChiplet扩展出了若干接口，辅佐CPU充沛开释通用核算才能。
