[OSRM-talk] Computing resources

[Andrew King]

Hi Roland,

Thank you so much for this useful link and advice. This is really helpful.

I have a couple of questions though:

1. The page refers to 280 GB of STXXL disk space, however, in August 2020, STXXL support was removed [commit 2d0b2ca9...21f96221]. Does this affect those requirements at all?

2. You mentioned splitting up the data. Would you then need to run two separate services (in your example) for each profile, or can they be recombined into one service after processing?

Many thanks
Andrew

This may be useful - https://github.com/Project-OSRM/osrm-backend/wiki/Disk-and-Memory-Requirements although I would expect the memory requirements to be a bit higher since this page was written.

As far as I know the OSRM processes use multiple cores.

You may want to split up the planet file before processing if you think the memory requirements are too high. i.e. you're probably not going to have a route from Australia to Europe for example, so they could be run in separate instances.

Thanks,
Roland

Hello,

We have recently taken on responsibility to create osrm instances for foot + bicycle + car routing with planet data, and we are trying to determine what compute specs are recommended in order to be able to process these.

Do you have this information available, or can you recommend a link where I can find out this information?

- How much memory is required/recommended to process planet data?
- Can the osrm processes (ie osrm-extract, osrm-partition, etc) make use of multiple cores?
- How long do each of the processes typically take to run on planet data?

Kind regards
Andrew
