 训练构建
 ==============
 
+InternLM 的训练流程可以归纳为两个步骤：
+
+1. 初始化
+
+    * 初始化模型、优化器、数据加载器、Trainer，生成不同种类的进程组，为混合并行的迭代训练做准备。
+    * 初始化Logger、Checkpoint管理器、Monitor管理器、Profiler，对迭代训练的过程观察、预警、记录。
+
+2. 迭代训练
+   
+    * 根据配置文件定义的张量并行、流水线并行、数据并行的大小，加载训练引擎和调度器进行混合并行训练。
+    * 在迭代训练中，调用 Trainer API 进行梯度置零，前向传播计算损失并反向传播，参数更新。

 命令行参数解析
 ----------------
 
-InternLM 使用 `argparse <https://docs.python.org/3/library/argparse.html>`_ 库来向InternLM运行时提供命令行参数配置。用户可使用 ``internlm.initialize.get_default_parser()`` 来获取 InternLM 的默认解析器，其中包含一些内置参数，用户可以向此解析器添加自定义参数。

 Torch Profiler
 -----------------
 
-InternLM 使用 ``internlm.train.initialize_llm_profile()`` 来收集和分析模型训练或推理期间的性能数据，如 CPU/CUDA/memory 等性能数据。这个实现基于 `torch.profiler <https://pytorch.org/docs/stable/profiler.html>`_ ，输出的性能分析 trace 文件可以使用 `tensorboard <https://www.tensorflow.org>`_ 进行可视化。

 用户如果想使用这个 torch 性能分析工具，需要在启动训练时传递 ``--profiling`` 参数以启用性能分析。完成 torch 性能分析后，用户可以在 ``{JOB_NAME}/{start_time}/traces/rank{}_dp{}_tp{}_pp{}`` 文件夹中看到性能分析结果。
