Subject Re: Recursion in S4
Date Mon, 11 Mar 2013 14:25:42 GMT

interestingly, we've had some related questions recently, you may have a look there

Conceptually, it sounds quite interesting, however it can get tricky in a distributed event
based system like S4, because a recursive algorithm introduces loops in the PE graph and that
is prone to deadlocks. And using unbounded queues is not very practical either.

Hope this helps,

recursive in nature. Is it possible to call a set of PEs recursively in S4 piper?
