NVIDIA opens Topograph for topology-aware GPU scheduling
NVIDIA released Topograph as an Apache-2.0 toolkit that discovers cloud or on-premises network topology, normalizes it, and publishes scheduler-ready Kubernetes labels, Node Feature Discovery resources, Slinky ConfigMaps, Slurm configuration or JSON. It includes Helm and native-package paths plus simulation utilities for testing without production hardware.
Why it matters: Distributed AI jobs are sensitive to GPU and fabric locality, yet topology data differs across clouds, InfiniBand, Spectrum-X and NVLink domains. A common discovery layer can make placement policy portable, but wrong or stale provider data can steer large…
