My data points are the opposite. 1. As it progresses from experiment to real use, most AI/ML/DL is taking place near where the data is. Since for many that data is on-premises, that is on-premises. For cloud services, it stays on the cloud. 2. The investment isn’t huge and is incremental, so there isn’t a strong barrier to buying the kit. Models never get ‘finished’ and require regular retesting on historical and new data, so they can keep it busy. The GPUs are plenty good enough because most of the frameworks parallelize (scale-out) easily. There is also a desire to test models on other similar data, but that data takes prep and a common data source. The cost of this sized dedicated storage is not prohibitive, but moving from/to the cloud can be. Most projects start very small to prove effectiveness. It isn’t a big tender to get started - unless you are doing Autonomous Driving... 3. There will be specialized solutions for inference, but that isn’t the same as training. IMHO, the specialized silicon or designs will be driven by using the AI near the edge within the constraints of power, footprint, etc. Training will still be scale-out & centralized. GPUs will still work for a long time, just like CPUs did. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
