Transforming Sequential Code to Parallel Code
Until recently, most Visual Basic code was written with a sequential and synchronous execution approach. Therefore, a lot of algorithms have been designed with neither concurrency nor parallelism in mind. Typically, you won't find algorithms that can be completely converted to fully parallelized and perfectly scalable code. It could happen, but it represents an ideal situation and it isn't the most common scenario.
When you have sequential code and you want to take advantage of potential parallelism to achieve better performance, you have to find hotspots. Then you can convert them to parallel code, measure speedups, identify potential scalability, and ensure that you haven't introduced new bugs while transforming the existing sequential code to parallel code.
The code discussed in this section is from code file Listing01.sln and shows an example of a very simple console application that runs two sequential ...
