CPU · Central Processing Unit
The host processor in a GPU node: runs the OS, storage and data pipelines, and orchestration while the accelerators do the tensor math; the CPU:GPU ratio is a node-design choice.
Current numbers
29 required cores; 100 GB host state. The 32-core pool passes the screen; its CPU ceiling is 112 requests/s.Size a host pool from CPU service demand — result and flip threshold
