How to parallelize sequential tasks using C # and parallel extensions?

I have the following method that is called sequentially:

  • private StringBuilder ReadPDF ();
  • private StringBuilder CleanText (StringBuilder sb);
  • private void ParseText ();

ParseText calls ReadPDF, which calls CleanText;

The PDF analysis that I am processing contains 15 MB of text, and it takes only 10 minutes to get all the data from the file using a regular kernel with two duos.

How can I parallelize these tasks?

edit: just to clarify, reading PDF takes very little time, the problem is the analysis of the extracted text, and more precisely in the CleanText phase. The reason I need to parallelize is because it cleans up one page instantly, but clearing 2k + pages takes a lot of time.

If you want to learn more about parallel programming, you can find good information and laboratories at the MSDN Parallel Computing Center .

MDN also has concurrent programming with the .NET blog .

There is also a good book Professional Parallel Programming with C #: Master Parallel Extensions with .NET 4 by Gastón Hillar
