Neither Concurrent Prolog nor Parlog can really be described as
"concurrent/parallel extensions to Prolog". The fact that they
have neither backtracking nor full unification make them rather
distant relatives to Prolog. They are powerful languages in
their own right, due to their natural handling of concurrency,
but in my experience trying to think of them in Prolog terms is
more a hindrance then a help, since it emphasises their
restrictions but not their power.
