# ADR-0003: Single-GPU first, multi-node ready

**Status:** Accepted

## Decision

Build the initial scheduler for one local NVIDIA GPU using Docker Compose and NVML, while keeping `ComputeNode` and `Accelerator` abstractions in the domain model.

## Rejected initially

- Kubernetes
- distributed inference scheduling
- multi-tenant cloud architecture

These add operational cost without solving the first product problem.
