Configuration

- id: comfyui-farm
  config:
    primaryUrl: 'http://127.0.0.1:8188'
    instances:
      - { id: gpu-18301, baseUrl: 'http://127.0.0.1:18301', label: '5090 shard' }
      - { id: gpu-18303, baseUrl: 'http://127.0.0.1:18303', label: 'Blackwell 102G' }
    needVramGb: 8
    maxQueueDepth: 3
    queueWeight: 1000
    probeTimeoutMs: 5000
    probeRetries: 1

How an instance is chosen (two stages)

1. Filter — unreachable, or free VRAM maxQueueDepth → out.
2. Rank — score = freeVramGb − queueDepth × queueWeight

The default queueWeight = 1000 is deliberate: queue depth dominates the ranking and free VRAM only breaks ties. That matches the intuition — an idle small GPU finishes sooner than a busy large one.

Prefer "biggest VRAM wins"? Set queueWeight: 0.
