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.

Creating parallel code in LabVIEW is simple; simply place parallel tasks parallel on VI block diagram and the tasks are executed in parallel. However this design doesn’t bend to use cases when the number of parallel tasks is not known at development time but needs to be specified at runtime.  In this post I present simple design pattern for parallel code execution based on recursion. In my next post I study the recursive concurrency in more detail.
