Description
Hello, I have a question. When I run the following command, I get the following error. Please help me resolve it
AS_SEND_LAT=3 AS_NVLS_ENABLE=1 ./bin/SimAI_simulator -t 96 -w ./aicb/aicb/results/workload/None-gpt_13B-world_size15360-tp8-pp16-ep1-gbs8192-mbs1-seq4096-MOE-False-GEMM-False-flash_attn-True -n ./AlibabaHPN_15360g_8gps_DualToR_SinglePlane_200Gbps_H100 -c astra-sim-alibabacloud/inputs/config/SimAI.conf
result:

Research direction
Reproduce the command with the shown workload, topology, and astra-sim-alibabacloud/inputs/config/SimAI.conf. Start at extern/network_backend/ns3-interface/simulation/src/internet/model/ipv4-address-generator.cc:385 and trace how 10.1.1.1 is assigned. Done means the simulator no longer aborts from the address collision, with the relevant behavior verified using the supplied command.
