Hello Aurélien,
I'm facing a similar issue... I've tried importing "Europe" on a linux
box with 16gb ram (+16gb swap). The process didn't complete and was
ultimately killed by the kernel when it requested the last bit of memory.
I'm also wondering if there's a way to generate the routing hierarchy on
a box like mine. If there's simply no way to make the import process use
less memory, it would be very helpful for me to know, how much memory
you need for Europe and how much for the entire World.
From my experience with importing single countries, I've learned that
importing the data is way more memory intensive than running the
osrm-server afterwards. Would it be possible to provide the
pre-calculated hierarchical data? (imho they would be architecture
dependent ... that sucks, but still, there are not _that_ many
architectures that are powerful enough to use OSRM and not powerful
enough to calculate the data by themselves...).
Best regards
Mark

Hello,
On Ubuntu Server 12.04, 8 GB of RAM and 248GB of free disk space.
During the "Generating edge-expanded graph representation" process, I
have this message : "Out of memory: Kill process"
To be sure, I made an .stxxl file in the Project-OSRM directory to
have an extra memory based on my only and main disk, but it fails as
before, exepted I don't receive any error message of type "config file
not found" or "error when allocating [...] attempting to [...]"
Can I do something ?
P.S.: In my .stxxl file, I put
"disk=/home/username/extra_disk,225280,syscall" (I have only one
physical disk)
Thanks !
