Re: [sumo-user] Parallel simulations

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

If you run your simulations in different processes and you have spare processors, then you should see speedup. 

Can you check with your system monitor whether your processor usage increases as expected?

Hello,

I currently have to carry out several experiments and wanted to run them in parallel on one PC.
Currently I have one python virtual environment in my project folder and several folders containing the same simulation.
I have tried to simply start my Python program several times and use a different folder as the simulation-source each time.

Unfortunately, I have noticed that when three simulations are running, they run three times slower, which means I don't save any time.

Is there anything I can do here to improve performance?
Can SUMO run several simulations at the same time when using python libsumo?

Many thanks in advance!

Kind regards
Andreas
