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.
- ryao 2y agoThe top500 says otherwise: https://www.infinibandta.org/infiniband-and-roce-advances-further-in-the-top500-november-2024-list/ https://www.infinibandta.org/infiniband-and-roce-advances-fu... Where are you getting your information?
- mrlongroots 2y agoI 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.
- ryao 2y ago#26 on the list uses AMD GPUs with infiniband: https://www.top500.org/system/180171/ https://www.top500.org/system/180171/ 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?
