Re: [sumo-user] The multi-threaded option in SUMO

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

- the simulation itself cannot be parallelized. There are some projects that spread the load across multiple instances and synchronize vehicles between the instances but they are not standardized.

- if you use online rerouting (http://sumo.dlr.de/wiki/Demand/Automatic_Routing) than you can parallelize the routing tasks with option --device.rerouting.threads

- duarouter supports option --routing-threads

- if you use traci and it slows down your simulation you can optimize communication load using subscriptions (http://sumo.dlr.de/wiki/TraCI/Interfacing_TraCI_from_Python#Subscriptions) or switch to libsumo which avoids socket communication (http://sumo.dlr.de/wiki/TraCI#Using_SUMO_as_a_library)

regards,

Jakob

Dear sumo users,

       Is there a multi-threaded option in SUMO to accelerate the simulation process，and what is it ?If not ,is there any way to accelerate the simulation process?

        Thanks in advance!
