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).
