Linux 7.2 Brings Cache Aware Scheduling for Modern CPUs

Modern server processors no longer resemble the relatively simple multi-core CPUs of a decade ago. Contemporary architectures such as AMD EPYC Turin and Intel Xeon 6 Granite Rapids are built around multiple chiplets, tiles, and independent LLC (Last Level Cache) domains. However, despite this dramatic hardware evolution, Linux scheduling behavior has remained surprisingly unaware of cache topology boundaries.

GPU Cluster TCO: Why Cheap GPUs Can Cost More to Run

A common misconception in AI infrastructure planning is that hardware dominates cost. In reality, GPU procurement typically accounts for only 25–30% of total cost of ownership (TCO) over a 5-year lifecycle.
