In my previous post I introduced the design pattern of worker pool based on dataflow recursion. In this post the pattern is revisited. I explain the theoretical concept of unlimited parallelism and concurrency that is a consequence of recursion in dataflow based programming languages. Furthermore I present how worker threads can be reused to manage system resource consumption.

The concept is nice and I have been waiting for NI to introduce such a concept for some years. I was positively surprised when I noticed that LabVIEW 2009 is shipping with this new feature.
