Description
I have run this code :
AS_SEND_LAT=3 AS_NVLS_ENABLE=1 ./bin/SimAI_simulator -t 16 -w ./example/microAllReduce.txt -n ./HPN_7_0_128_gpus_8_in_one_server_with_100Gbps_A100 -c astra-sim-alibabacloud/inputs/config/SimAI.conf
It takes "microAllReduce.txt" and "HPN_7_0_128_gpus_8_in_one_server_with_100Gbps_A100" as workload and topology , performs two AllReduce operations and generates the execution time of each communication. But I was wondering if a node (like node 0) fails, can the workload still be performed? Can I simulate the physical failure by changing parameters in the topo file? Thanks!

Research direction
Start by running the supplied SimAI_simulator command and reading the referenced microAllReduce.txt workload, HPN_7_0_128_gpus_8_in_one_server_with_100Gbps_A100 topology, and SimAI.conf configuration. Determine whether node failure is already represented by topology parameters; done requires a clear answer or an agreed, reproducible way to simulate a failed node.
