DGX Spark chaining

DGX Spark chaining means connecting several NVIDIA DGX Spark units — small, palm-sized personal AI computers — with cables so they act together like a single, more powerful machine.

Think of it like joining several mini-fridges side by side to make a big storage space, when one fridge alone can't hold everything. A single computer has limits on how much it can compute and store, but linking several together lets people run bigger, more complex AI models in a home or office setting.

AI models released these days keep growing larger, often too demanding for a single personal device to handle. Chaining spreads that load across multiple machines, which is why it's drawing interest from people who want to run large AI models on their own hardware without sending data to internet servers.

News coverage describes it in ways like "NVIDIA AI's official account introduced a chaining guide for linking multiple DGX Spark units." It should be noted, though, that details like how many units are linked or which models run at what speed aren't confirmed by this news alone.
