The only think I am happy about all this AI hype is Infiniband is getting some love again. A lot of people using RoCE on Connect-X HBAs but still a lot of folk doing native IB. If HPC becomes more commonplace maybe we get better subnet managers, IB routing, i.e all the stuff we were promised ~10+ years ago that never had a chance to materialise because HPC became so niche and the machines had different availability etc requirements than OLTP systems that didn't demand that stuff getting built out. Especially the subnet managers as most HPC cluster just compute a static torus or clos-tree topology.
There was a time I was running QDR Infiniband (40G) at home while everyone else was still dreaming of 10G at home because the adapters and switches were so expensive.
