在Megatron-DeepSpeed中,mpu模块的initialize.py文件负责并行环境的初始化。假设有两个节点,每个节点有8个GPU,共计16个GPU,编号分别为Rank0至Rank15。用户可以根据需要设置流水线并行度和张量并行度,例如流水线并行度为4,张量并行度为2。 流水线并行:将整个模型划分为多个子模型(sub_model),每个子模型由一组连续的...
初始化功能的核心是函数 initialize_model_parallel,其主要的参数就是用户指定的张量并行数tensor_model_parallel_size_以及流水线并行数pipeline_model_parallel_size_。基于这两个用户参数来计算出各种分组。 def initialize_model_parallel(tensor_model_parallel_size_=1, pipeline_model_parallel_size_=1, virtual_pi...

These two structures are used by the PHY driver to initialize DDRPHYC CSR registers and to control the execution of the PHY firewall training at step G, preceded by the PHY firewall load into IMEM by the driver at step D; parameters are passed between the PHY driver and the PHY...

In the MC9S08AW60 Series, it is usually best to re-initialize the stack pointer to the top of the RAM so the direct page RAM can be used for frequently accessed RAM variables and bit-addressable program variables. Include the following 2-instruction sequence in your reset initialization ...
