百度飞桨框架3.0引入动静统一自动并行 简化大模型训练开发
飞桨框架3.0版本发布，核心升级为动静统一自动并行技术，旨在简化大模型分布式训练流程，提高开发效率。新版本支持四维至五维混合并行技术，采用多种并行方式，如数据并行、张量模型并行、流水线并行和分组参数切片并行，有效提升大模型训练效率。自动并行技术通过张量切分语法标记，自动推导分布式切分状态和添加通信算子，降低开发难度。自动并行原理包括分布式张量表示、切分推导、切分转换，支持重切分能力。飞桨提供动静统一执行模式，支持从动态图到静态图的转换，兼顾便捷性和效率。性能优化策略包括算子融合、流水线编排调度、通信-计算Overlap和通信融合，通过配置选项即可开启，进一步提升分布式训练性能。
