Searchgraph World Map: requirements

[Bernd Welter]

Cheers,
one of our developers calculated a search graph for the whole world map (PTV_World_City_Map_Premium_2022_2H). Not impossible, but the process is quite hungry for ressources (both time and memory)... here's a quick summary:

• Status: it worked
• 64 GB memory + 100GB pagefile
• Temporarily the process "ChNodeOrderGenerator" grabbed more than 150 virtual memory
• Complete creation took more than 4 hours

Please be aware that this was more or less an academic test (in the context of PTV xIntermodal). In a production environment such a graph would also require much memory and as users normally deal with a clear geographic region such as Europe XOR North America we do not recommend to create such enormous structures if not really needed.

I did it - because I was able to do so:

2023-06-05 12:46:04,268;8556d10a-7d80-4662-b552-bdaeef61b422;127.0.0.1;unknown;unknown-port;notebook.bwe;XData.createHighPerformanceRoutingNetwork;true;-;-;-;default;m0001;0;4892615;4893417;async;-;-

So within a 1:20 hrs time I successfully computed a WORLD HPR on my 64GB memory driven laptop.
The output file is about 14GB in size.
But as mentioned above: you probably better create continental grahphs based on GEOGRAPHIC RESTRICTIONS such as

• allowed countries=["zz-eur"]
