Description
我在模拟4机32卡运行GPT7B的情况，运行到chunk size is: 4 , size is: 4 , layer_num is: 74762 , node: 0时，运行结束没有任何报错或警告，但生成的ncclFlowModel_EndToEnd.csv、ncclFlowModel_detailed_36.csv中是空的。换成其他大模型也有类似情况，运行microAllReduce.txt是没问题的。
运行命令如下：
AS_SEND_LAT=3 AS_NVLS_ENABLE=1 ./bin/SimAI_simulator -t nproc -w ./gpt_7B-world_size32-tp4-pp1-ep1-gbs8192-mbs1-seq4096-MOE-False-GEMM-False-flash_attn-True.txt -n ./HPN_7_0_32_gpus_8_in_one_server_with_single_plane_100Gbps_A100 -c astra-sim-alibabacloud/inputs/config/SimAI.conf | tee gpt7b.log
生成的log见附件
gpt7b.log

Research direction
Start by reproducing the command shown in the issue with SimAI_simulator, using gpt_7B-world_size32-tp4-pp1-ep1-gbs8192-mbs1-seq4096-MOE-False-GEMM-False-flash_attn-True.txt and the HPN topology input. Inspect gpt7b.log and compare the empty ncclFlowModel_EndToEnd.csv and ncclFlowModel_detailed_36.csv with a successful microAllReduce.txt run; done means the simulation completes with populated output files or reports the failure clearly.
