Hi all,
Just enquiring if anyone has an up-to-date value for the required RAM to
extract/prepare the planet PBF on OSRM v4.9.1? Below is the output from
extraction on a 64 GB RAM machine:
[info] Input file: planet-latest.osm.pbf

[info] and 610970822 edges
[info] Graph loaded ok and has 610970822 edges
[warn] std::bad_alloc
From my reading, this is caused by running out of RAM. The only files
created were:
-rw-r--r-- 1 root root 25G Mar 7 18:57 planet-latest.osrm
-rw-r--r-- 1 root root 118M Mar 7 19:00
planet-latest.osrm.names
-rw-r--r-- 1 root root 15M Mar 7 19:00
planet-latest.osrm.restrictions
-rw-r--r-- 1 root root 20 Mar 7 12:33
planet-latest.osrm.timestamp
Which obviously means preparing gives the following:
[info] Input file: planet-latest.osrm
[info] Profile: profile.lua
[info] Threads: 12
[info] Loading edge-expanded graph representation
[info] Opening planet-latest.osrm.ebg
[warn] [exception] osrm input file misses magic number. Check or
reprocess the file
Thanks.
Kind regards,
