How do I run multiple instances of Graph Engine on the same computer?

Please see here: https://www.graphengine.io/docs/manual/Config/config-v2.html#server

When defining multiple servers on the same computer, you can put assemblies in different folders. In the config file, you can identify each of them using a combination of address and build path.

There are two binding rules for an instance:

• The Endpoint property corresponds to one of the network interfaces of the machine running the Graph Engine instance.
• If AssemblyPath is specified, it matches the directory where the executable Graph Engine instance is located.

Also check the version of your package GraphEngine.Core. Only the latest package supports the new configuration file format.
