AI Infrastructure Success Depends On Network Optimization As Much As Raw Compute Power

For Massive Models, You Need More Than Just Massive Compute
As AI clusters scale to thousands of nodes, networking has become the critical performance bottleneck. Mixture-of-Experts and heterogeneous hardware architectures shift computational demands onto interconnect efficiency, making GPU synchronization and latency management essential.
The article argues that more GPUs do not guarantee more performance, and that companies must design AI infrastructure as an integrated system where network topology, communication libraries, and model architecture are optimized together to prevent expensive compute resources from sitting idle.
