Writing a parallel For loop is an easy task, although it is important to remember that you can use parallelism against intensive and time-consuming operations. Imagine you want to invoke the code defined at the beginning of this section for a finite number of times to simulate an intensive processing. This is how you would do it with a classic For loop:
Sub ClassicForTest() For i = 0 To 15 Console.WriteLine(i.ToString + GetThreadId()) SimulateProcessing() NextEnd Sub
Nothing new here; the code writes the thread identifier at each step and simulates an intensive processing. If you run the code, you get the result shown in Figure 41.1, where you can see how all the work relies ...
