Why engineers and teams are moving LLM inference and fine-tuning onto DGX Spark and GB10 systems: bigger models than one unit can hold, private data that never leaves the building, and a desk-side box that matches NVIDIA's production stack.
Does the CPU matter for GPU inference? Dell R7525 (EPYC) vs R740xd (Xeon) compared on PCIe, memory bandwidth and GPU count.
When on-prem AI inference needs a data center switch, when a DAC or ring is enough, and what lossless RoCE Ethernet requires.
