In this webcast, Fedor Pikus uses practical examples of (mostly) lock-free data structures, with actual implementations and performance measurements, to cover the fundamentals of lock-free vs. lock-based programming. We'll explore the reasons to write lock-free programs (as well as the reasons not to). We'll learn, or be reminded of, the basic tools of lock-free programming and consider a few simple examples before trying something more difficult, just to see how insanely complex the problems can get. Having been burned by the complexities of generic lock-free algorithms, we'll take a more practical approach: assuming we are not all writing STL, we'll try to outline some limitations we can live with. Even if the specific limitations and simplifying assumptions used in this talk do not apply to your problem, you'll leave understanding how to find such assumptions and take advantage of them, because chances are, you can use lock-free techniques to write code that works for you and is much simpler than what you were writing before.
