Threads and Shared Variables in C++0x

Explore the introduction of threads and shared variable semantics in C++0x in this keynote address from BoostCon 2011. Delve into the design principles behind the new language features, focusing on the goal of providing meaningful multithreaded programs with sequential consistency by default. Examine the concept of data races as erroneous and the introduction of atomic operations for specially identified objects. Gain insights into the memory model defining shared variable semantics and its interaction with the atomics library. Learn about the challenges and surprises encountered during the development process, as well as the efforts to maintain consistency with past practices while addressing previous mistakes.
