Announcements

• Today's lecture
  • Review the first multithreading example from this past Wednesday's lecture, highlighting similarities between multprocessing and multithreading, pointing out differences.
  • Work through two versions of a multithreaded program where the main thread of execution shares data with each of the baby threads it creates.
    • Version 1 is intentionally broken to illustrate the most obvious of race conditions.
    • Version 2 provides a very simple fix so that the race condition is no longer present.
  • Motivate my decision to move from C to C++ for its more robust and error-resistant treatment of threads.
  • Work through two or three C++ threading examples.
• Assigned Reading
  • You're reading all of Section 12.1 and Sections 12.3 through Sections 12.8 right now, skipping those subsections that refer to networking and servers.
    • Chapter 12 is actually the fourth chapter of the reader.
    • Code examples are in C, but the concepts are largely the same regardless of language.
  • Once we learn networking, we'll come back and hit on some of these excluded sections.
