[sumo-user] Question on Running duaIterate.py with Multi-threading

[Aslan Yurekli Richard <aslanyureklirichard@xxxxxxxxx>]

Hi,

I am currently working on a machine learning project that requires repeated SUMO simulations. I am using the tools/assign/duaIterate.py script, but I have encountered performance limitations. For example, running 26 vehicles over 20 iterations takes approximately 45 minutes.

When I check the activity monitor, I see that RAM usage stays around 20%, while a single CPU thread is consistently at 100%. I assume this bottleneck arises because SUMO runs on a single thread.

Could you advise me on how to run the following code using multiple threads, or suggest a more efficient setup for parallel execution?

To reproduce a similar simulation, please use the code below:

```

python3 $SUMO_HOME/tools/assign/duaIterate.py \

  -n osm.net.xml.gz \

  -r taxi_trips.xml \

  -+ taxi_vtypes.xml \

  -l 20 \

  --max-convergence-deviation 0.01 \

  --continue-on-unbuild

```

Best regards
