Description

Thanks for open source your deepspeed transformer code.

At deepspeed_cuda.py function init_transformer_weights, the adjust init range feature is applied to rank 0 only. Can you explain why rank 0 only? Shouldn't it be applied to all ranks? Thanks.

Research direction

Read deepspeed/pt/deepspeed_cuda.py at init_transformer_weights around line 483, then trace how the rank-0 condition relates to distributed initialization. The issue names no test or other entry point; done means providing a clear explanation of the rank-specific behavior and documenting the expected initialization semantics if needed.
