Global Settings

The global: section contains settings that affect the entire system.

speed_factor

Controls how fast the simulation runs relative to real time.

ValueBehavior
1Real-time (1 second simulation = 1 second wall clock)
300300x speed (1 hour simulation = 12 seconds wall clock)
-1Maximum speed (no delays between messages)
global:
speed_factor: 300

Estimating Runtime

With the SURF workload (~7 days of data):

Speed FactorApproximate Runtime
17 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
