Systems

System components handle more technical aspects of the simulation. The mandatory System component in VLMP is “simulationName,” which must always be present as it names the simulation. An optional component is “backup,” which, if added, performs a simulation backup at specified intervals. Here is an example of the System category with two components, the mandatory “simulationName” and “backup”:

"system":[
    {"type":"simulationName",
     "parameters":{"simulationName":"exampleName"}},
    {"type":"backup",
     "parameters":{"backupIntervalStep":1000,
                   "backupFilePath":"backup"}}
]

This example shows how, besides the simulation name, a backup component is added. This component will perform a backup every 1000 steps and save it in the file named “backup”. When this component is added, it not only enables backup at certain intervals but also allows for rebooting the simulation if an error occurs.

The complete list of System components is as follows:

• backup

• seed

• simulationName

backup

author

Pablo Ibáñez-Freire

Component used to add a backup system to the simulation. When this component is added to the simulation, the simulation will create a backup of the simulation every backupIntervalStep steps. The simulation will try to restore the simulation from the backup if the simulation crashes.

Required Parameters

Name	Description	Type	Default
backupIntervalStep	Interval of steps between backups	ullint

Optional Parameters

Name	Description	Type	Default
backupEndStep	Step at which the backup ends	ullint	MAX_ULLINT
backupFilePath	Path to the backup file	str	backup
backupStartStep	Step at which the backup starts	ullint	0

Example:

{
        "type": "backup",
        "backupIntervalStep": 1000,
        "backupFilePath": "backup"
}

seed

author

Pablo Ibáñez-Freire

This component sets the seed for the random number generator

Required Parameters

Name	Description	Type	Default
seed	Seed for the random number generator	int

Example:

{
        "type": "seed",
        "seed": 123456
}

simulationName

author

Pablo Ibáñez-Freire

Essential component for naming a simulation. This component is compulsory in every simulation configuration as each simulation requires a unique name. The ‘simulationName’ component assigns a descriptive and identifiable name to a simulation, facilitating its management and reference within the system. This name is used as the primary identifier for the simulation across various components and modules.

Required Parameters

Name	Description	Type	Default
simulationName	Unique name assigned to the simulation	str

Example:

{
        "type": "simulationName",
        "simulationName": "MyUniqueSimulationName"
}
