However, there do come times when updates are necessary. It would be convenient if there was some general update-side counterpart to these techniques, but sadly there is not yet any such thing. Nevertheless, there are a number of specialized update-side techniques whose performance and scalability rival those of RCU and hazard pointers. This talk will discuss several of them, one of which is a solution to a challenge to the speaker at the 2014 Issaquah C++ standards committee meeting. This talk will also provide an outlook into the future of low-overhead scalable updates. -- Paul E. McKenney has been coding for almost four decades, more than half of that on parallel hardware, where his work has earned him a reputation among some as a flaming heretic. Over the past decade, Paul has been an IBM Distinguished Engineer at the IBM Linux Technology Center. Paul maintains the RCU implementation within the Linux kernel, where the variety of workloads present highly entertaining performance, scalability, real-time response, and energy-efficiency challenges. He is also the editor of "Is Parallel Programming Hard, And, If So, What Can You Do About It?" Prior to that, he worked on the DYNIX/ptx kernel at Sequent, and prior to that on packet-radio and Internet protocols (but long before it was polite to mention Internet at cocktail parties), system administration, business applications, and real-time systems. His hobbies include what passes for running at his age along with the usual house-wife-and-kids habit.Website: http://www.rdrop.com/users/paulmck -- Videos Filmed & Edited by Bash Films: http://www.BashFilms.com/ *-----* Register Now For CppCon 2022: https://cppcon.org/registration/ *-----*
