Hi,
I have two erlang nodes running in distributed mode. Executing self() in the shell of one of these nodes will return a "local" pid of a process like: <0.36.0>. The first digit indicates the "node index". If the pid would be sent to the process running on the other node, it will be translated to something like <4831.36.0>. Is there any simple way to get the "node index" of the other node without sending any messages between nodes?

Michal

I realised that if you spawn a process on a remote node, you get the pid of the new process...so for debugging (and this is my case) I can execute:

Code:
(node1@somehost)1> spawn(node2@somehost, fun() -> ok end).
<4811.41.0>
