No it doesn't, the process id is totally irrelevant and can be any number
you want to assign it. If you want you can assign it the same number on
all your routers, but you don't have to.
The setting that you need to match in OSPF is the area number on routers
that you want to become adjacent.
When you think of OSPF don't even think of autonomous systems. ASes have
to do with BGP. I know that Cisco uses the word autonomous system to
describe EIGRP and IGRP routing domains but that is a different concept and
it is easy to become confused when you switch back and forth between the
two meanings.
