Description

Hello, after simulating with SimAI-Simulation, I output three CSV files. Both ncclFlowModel_EndToEnd.csv and ncclFlowModel_test1_dimension_utilization_0.csv have content, but only ncclFlowModel_detailed_.csv is empty. I want to know what type of communication happened at what time during the simulation, how much data was communicated, the communication time, and the detailed process of who communicated with whom. How should I obtain this detailed process file? Looking forward to your reply, thank you!

Research direction

Start by reproducing the simulation that generates ncclFlowModel_EndToEnd.csv, ncclFlowModel_test1_dimension_utilization_0.csv, and the empty ncclFlowModel_detailed_.csv. Trace where the detailed CSV is produced and compare its inputs with the two populated outputs; done means the file is generated with the requested communication timing, data volume, duration, and sender/receiver details.
