Description

Describe the bug
I use 8 * A100-80GB GPUs to fine-tune a 72B model, but when it loads 16/37 safetensor, it always been shutdown for no reasons without any hints!

The error is as follows:

Loading checkpoint Shards"43%16/37 [19:49<25:57,74.18s/it] 
 Sending process4029695 closing signal SIGTERK
failad (edtcote: -5) lcalrank:5 

I use zero-3 and acclerate to launch my script. The command I use is accelerate launch --config_file xxx --gpu_ids 0,1,2,3,4,5,6,7 xxx.py.

The deepspeed file is as follows:

Expected behavior

I think it should load all of safetensors, what's more, during the loading process, I notice that gpu memory is still 0.

Research direction

Start by reproducing the reported command with the provided DeepSpeed ZeRO-3 configuration on 8 A100-80GB GPUs while loading the 72B model. Inspect the checkpoint-loading stage around shard 16/37 and collect the process termination and system logs. Done means the shutdown cause is identified and loading completes or the issue is narrowed to a documented failure condition.
