Description (last modified by )
This module scales badly for large systems. The following table shows the time of this module in comparison to the entire back end time for ScalableTestSuite.Electrical.TransmissionLine.ScaledExperiments.TransmissionLineModelica_N_xxx.
| time [s] for | ||
|---|---|---|
| N | constantLinearSystem | backend |
| 10 | 0.03 | 0.10 |
| 20 | 0.05 | 0.17 |
| 40 | 0.10 | 0.38 |
| 80 | 0.29 | 0.86 |
| 160 | 1.46 | 3.47 |
| 320 | 16.75 | 27.64 |
| 640 | 260.1 | 333.84 |
That means that the module need more than 75% of the back end time for N=640.
