Ariadne Simulator |
1. Description
With Ariadne-simulator run-events of an earlier competition can be 'replayed', for simulation of a competition, testing of procedures, and testing of Ariadne modules.
Ariadne-simulator has four competing units, which can be started to perform a run. The run to perform is taken from the T990-simulation-runlist table, which states the endcondition of the run (normal completion with an elapsed time, DNF (start without finish), initialization of a run). The simulation runlist can be populated with real runevents from a earlier competition. Run types can be changed in the runlist, as to add extra DNF and initializtion runs.
The simulation-CU's are started by the Simulation-manager. This module looks every 10 seconds if a simulation-CU is available, and if so, supplies it with the id of a run te be executed, and starts the Simulation-CU. The status of an simulation-CU is maintained in the table T992-Simulation-CU-status.
Used tables:
T990-Simulation-runlist
| Attribute | Type | Length | Remark, example | |
| simulation-run-id | counter | internal id | ||
| time-stamp | data | is sorting order of the runlist | ||
| run-type | numeric | integer | 2=normal completion; 3=initalization; 4=DNF | |
| series | numeric | integer | 1, 2 | |
| start-number | numeric | integer | 1 - 999 | |
| elapsed-time | numeric | double | time in milli-seconds | |
| processed | yes/no | whether the run is yes /no processed |
This runlist is processed in order of time-stamp
T992-Simulation-CU-status
| Attribute | Type | Length | Remark, example | |
| CU-id | numeric | integer | number of the simulation competing unit (1,2,3,4) | |
| CU-available | yes/no | wheter a CU is available for processing a new run | ||
| simulation-run-id | numeric | double | id of the run to be performed |
The simulation-CU's and the Simulation-manager are forms. The timing is realized with the timer-facility of the forms.
A active simulation-CU gets the specified run from the runlist. If the
run-event-type is an initialization, the simulation-CU only puts a initialization-event
in the T600-Run-event-table. If the run-type is a normal completion, the
simulation-CU first puts a start-event in the T600-Run-event-buffer, and
after the elapsed time is past, it puts a finish event in the T600-Run-event-buffer.
If the run-type is a DNF, it only gives a start-event, and no finish event.
