Here's a picture of what I was talking about:

Now, the two while loops, as shown here, have no dependencies between each other and are indeed processing in parallel. However, there are various mechanisms in LabVIEW to exchange data between the two loops, the most common being queues, in which case they process concurrently.

You can also have a for loop iterating on an array.

In LabVIEW, it's nice because it's trivial to configure the loop iterations to occur in parallel (if there are no dependencies between iterations), using all available cores in the computer.

And by pattern matching I meant something like the pattern matching and type destructuring you find in SML, Ocaml, F#, and Elixir.

Yes, that's really just abstracting away the control flow I was depicting in my simple diagram. It's treating "while" as a higher order function of sorts, with its own input(s) of type "data flow diagram connecting types Xs and Ys". That's the best you can do if your language only really deals in dataflow, as w/ LabVIEW ]. And that's really what leads to the difficulty you mention with pattern matching. Pattern matching on a variant record is inherently a control-flow step, even though destructuring variables in a single variant should clearly be depicted as data flow.
