Compose GPUs and accelerators to Kubernetes nodes on demand from disaggregated pools. Learn CoHDI's composition model, fabric, dynamic device scaling, and scheduling.

Welcome to CoHDI: Composable Hardware for Kubernetes.

A practical, in-depth guide to CoHDI (Composable Hardware Disaggregated Infrastructure), the open-source platform for dynamically composing hardware to Kubernetes nodes. Learn how CoHDI makes hardware fluid: the static hardware problem (stranded, wasted accelerators), composable disaggregated infrastructure (disaggregation, the fabric, composition), the CoHDI architecture (bridging Kubernetes and composable hardware), resource pools and the fabric (matching demand to supply), dynamic device scaling (compose on demand, release when done), Kubernetes integration and scheduling (resource requests, device plugins/DRA), the composition lifecycle and operations (failures, clean release, correct state), operations/best practices/safety, and CoHDI in practice.
