re[2]: Clusterwide pids

[Jordi Polo <mumismo@wanadoo.es>]

Let us summarize a bit:
-most people agrees we need unique CPID even if the process is something we 
know is not going to migrate as init. 
-that CPID will be node number + local pid
- We don't want to recompile userspace apps so we do our own system calls, 
which  maybe :
	* getcpid to get the ¿64bits? with the standard getpid returning the low 32 
bits of the CPID
	* getnode(pid) with 0 if process if local , nonzero otherwise.
Then we have a question left: ¿How we manage to get unique CPIDs ?
What number node a machine must have, ¿read it from /etc? ¿read it a la HDLC?

i have missed something?
