Nvidia patents method to sync data across split processor chips

Nvidia has filed a patent for a way to coordinate multiple processor chips that are physically separate but work together. The system uses specific hardware circuits on each chip to track when data is ready, ensuring all parts of the processor stay in sync.

Why it mattersThis technology could help Nvidia build larger, more efficient graphics cards by linking multiple smaller chips together without losing performance.

In the filing’s own words

This disclosure describes supporting distributed graphics and compute engines in a multi-dielet processor, such as, for example, a multi-dielet graphics processing unit (GPU), architectures and synchronization in such architectures. Each multi-dielet processor includes a hardware-implemented remapping capability and/or a hardware-implemented memory barrier capability.

What exactly they claim (claim 1)

1. A multi-dielet processing system comprising: a plurality of processors on respectively different dielets, comprising at least a first processor on a first dielet and a second processor on a second dielet, wherein the plurality of processors each comprises at least one hardware engine; and a respective memory barrier handling circuit arranged on each of the first and second dielets, wherein each memory barrier handling circuit is configured to determine a state of a memory barrier based on acknowledgements received from the same dielet and one or more acknowledgements received from other dielets.
