I concede that the specifics of what I said were wrong, but the larger point was not.
If you buy a single DGX H100 rack and run LINPACK, you automatically get TOP500-grade numbers. Infiniband is a solid product, if not the best commercial offering for AI/ML, but no one buys it for an HPC cluster separately from the DGX boxes.
You can likely find more. Infiniband has been excellent for HPC since the 2000s. That includes all HPC workloads, not just AI/ML.
Excuse me if I do not believe your claims concerning infiniband. They contradict not only actual data, but also what I have heard from people I consider experts.
Also, you did not answer my question concerning the origin of your information. I notice from another comment if yours that you have been talking to a LLM about this conversation. Have you been posting things that a LLM tells you?
