https://cppcon.org/ --- Single Producer Single Consumer Lock-free FIFO From the Ground Up - Charles Frasch - CppCon 2023 https://github.com/CppCon/CppCon2023 In this session we will construct a Single Producer Single Consumer Lock-free Wait-free Fifo from the ground up. But why write our own if we can get one from reliable sources such as Boost.Lockfree? There are a couple of answers to this question. Writing such a fifo is a fairly gentle introduction to lock free programming. There are some interesting performance optimizations that can be made. There may be some specific requirements that are not met in out-of-the box implementations. In the presentation we will first develop a simple circular fifo. Next we will make it thread-safe as well as lock-free and wait-free. After that we will address issues associated with cache coherency and false sharing in particular. We will show a few additional optimizations that can be added as needed to meet specific requirements. Finally, the performance of our fifo will be compared with a few out of the box implementations. Along the way we will touch on subjects such as thread safety, data-races, false sharing, object lifetime, and relaxed atomics. --- Charles Frasch Charles Frasch is a Senior Core Developer with the IEX Group where he is working to re-platform their core trading infrastructure in modern c++.
