Overcoming Copper Limits: Scaling GPU Pods with Passage at Supercomputing 2025

Principal Solutions Architect Taylor Groves explains how Lightmatter Passage overcomes the physical limitations of copper to scale compute pods from 144 GPUs to thousands. This SC25 recap details how the platform achieves high bandwidth density and low energy consumption to drive next-gen system performance:

Massive Scaling: Expanding scale-up pods to thousands of accelerators.

Performance: 2.6x improvement on Mixture of Experts (MoE) models.

Efficiency: Lowest picojoule-per-bit with high reliability.

Design: Detachable fibers and external lasers.
