Sorry to hound you for the third time, but this is wrong:

> Infiniband is extremely popular in the HPC space

Not anymore. There used to be Cray Aries/GNI, psm/psm2, and now there's Slingshot, the new Cornelis stuff etc. There's almost no Infiniband now.

The top500 says otherwise:

Where are you getting your information?

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.

#26 on the list uses AMD GPUs with infiniband:

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?
