Summary
LRF-3D automatically reroutes data around faulty nodes in 3D networks-on-chip, aiming to keep processors running despite manufacturing defects and silicon degradation.
36 test scenarios showed path lengths deviated just 1.64% from a reference algorithm even when up to 50% of nodes failed, indicating the system can avoid on-chip “dead ends” without a full network map.
At 13%-30% node failure rates, the algorithm delivered packets in 86% of attempts and made routing decisions 16.7 times faster than A* and 22.5 times faster than LOFT.
The researchers said route quality beat LOFT by more than 137 times; next they plan real-chip tests on power use and data-transfer rates for data centers, supercomputers and AI systems.
