We use the Stata implementation OSRMTIME from Stephan Huber at Regensburg University which can split the data across threads (we have 2 CPUS with four cores each, and two threads per core). So 16 threads on a 3.5 Ghz Xeon and 64 GB of RAM, and if the network traffic is low (like on holidays) I can get about 1.2 million routes per hour in the United States.
Of course, this requires having Stata, but we find it is a pretty good way to do batch routing. I recently did about 460 million routes. But it only returns distance and time, not the actual route, if that matters. http://www.uni-regensburg.de/wirtschaftswissenschaften/vwl-moeller/medien/huber/osrm_paper_online.pdf osrmtime: Calculate Travel Time and Distance with ...<http://www.uni-regensburg.de/wirtschaftswissenschaften/vwl-moeller/medien/huber/osrm_paper_online.pdf> www.uni-regensburg.de The Stata Journal (2016) 16, Number , pp. 1{8 osrmtime: Calculate Travel Time and Distance with OpenStreetMap Data Using the Open Source Routing Machine (OSRM) ________________________________ From: Patrick Agin <[email protected]> Sent: Friday, May 11, 2018 1:14:31 PM To: Mailing list to discuss Project OSRM Subject: [OSRM-talk] map matching service for a huge number of requests Hi, I want to call the map matching service for nearly a million of routes. I calculated that the task could take 10 hours on my laptop to complete. I was wondering if there's someone who faced the same problem and who addressed it in parallel, maybe with Spark? Another tool or way? Any hint is greatly appreciated! Patrick ****WARNING**** This information may be confidential. It is intended only for the addressee(s) identified above.
