Re: [sumo-user] faster simulation in GUI
|
I suspect this has to do with console output which is horribly slow on windows. Try setting the option --no-step-log
Hi Michael,
I'm on windows and not using TraCI. I made a more detailed experiment to see what is really happening. First of all, since I am using laptop and it was not plugged in, it was on battery saving mode (not full performance), which made SUMO without GUI extremely slow but had no effect on GUI mode!
After plugging the laptop (core i7 2.1 GHz, 16GB RAM, GPU 128MB + 2GB) I observed the following timings invoking SUMO directly from Command prompt for both micro and meso for average of 3 simulation runs (8,000 sec of simulation on Sioux-Falls network with totally 7712 vehicles in the network):
meso-gui:12 sec
meso: 32 sec
micro-gui: 72 sec
micro: 75 sec
Here the meso-gui is extrenelky faster than meso without gui, even though the visualization in meso is not reflecting vehicle movements!
In order to measure the times exactly, I started all the simulations in R and the exact timings are:
meso-gui:11.61 sec elapsed
meso: 14.05 sec elapsed
micro-gui: 70.24 sec elapsed
micro: 44.73 sec elapsed
Interestingly, invoking SUMO via R cuts the simulation time of the without GUI mode for both micro and meso in half (but has no effect on GUI mode; I have no idea why and how).
Cheers,
Sasan

Hi Sasan,
I cannot think of a reason why the GUI version would run faster. Which platform are you on? Do you use TraCI?
Best regards,
Michael
