Re: [sumo-dev] [sumo-devel] Parallelizing sumo

[Jakob Erdmann via sumo-devel <sumo-devel@xxxxxxxxxxxxxxxxxxxxx>]

Hello,
- the simulation itself is mostly single threaded. The only part that
supports parallel operation is routing (using the --device.rerouting
options). duarouter can also do routing in parallel
- we have some plans to work on further parallelization in 2018
- the traci library supports connecting to multiple simulations at the same
time by using traci.connect and storing the returned connection object or
by using traci.start with a label argument and the retrieving the
connection instance using traci.getConnection (with that label).
(getConnection is only available in the latest development version / 0.32.0)
- @Menno: you can start sumo-gui with the options --start and --quit  in
order to automatically start the simulation upon loading (and quit it after
finishing)
- @Menno: libsumo is due to be released tomorrow (still in alpha stage).

regards,
Jakob
