Global Settings
The global: section contains settings that affect the entire system.
speed_factor
Controls how fast the simulation runs relative to real time.
| Value | Behavior |
|---|---|
| 1 | Real-time (1 second simulation = 1 second wall clock) |
| 300 | 300x speed (1 hour simulation = 12 seconds wall clock) |
| -1 | Maximum speed (no delays between messages) |
global:
speed_factor: 300
Estimating Runtime
With the SURF workload (~7 days of data):
| Speed Factor | Approximate Runtime |
|---|---|
| 1 | 7 days |
| 60 | ~2.8 hours |
| 300 | ~34 minutes |
| -1 | ~10 minutes |
calibration_enabled
Enables the calibrator service for automatic parameter tuning.
global:
calibration_enabled: true
When true:
- The calibrator container starts
- Grid search runs periodically to optimize topology parameters
- Calibrated topologies are published to
sim.topology - Simulator uses calibrated values for predictions
When false:
- Calibrator does not start
- Simulator uses the original topology without modifications
