I've been working with Dataflows for past couple of months and I agree.
Dataflow or Flow-Based programming is a very nifty paradigm to express
programs. Especially when it comes to parallel execution.
I am not working in a signal processing background where this technique
is well known. I investigated this programming paradigm in the past for
one specific linear algebra application (Results can be seen here: and here:
We constructed the dataflow tree completely dynamicly in an almost
natural way (modulo the syntatic differences). So i have to disagree
with Dave Abrahams that purely compile-time based dataflow "wiring" is
the most efficient way.
