Serial and parallel pipelines in modern C++
A pipeline is a chain of processing elements such as functions, threads etc., arranged so that the output of each element is the input of the next. We often encounter this pattern in practice. C++ also allows us to write in this way, e.g. using the std::ranges library with its characteristic overloaded pipe operator |. But modern C++ enables much more and this will be discussed in this talk. First, we’ll show how to implement a custom pipeline framework that employs std::expected, available since C++23. Secondly, we will show pipelines in the serial version, where the functions communicate the results of their calculations, as well as in the parallel version, in which at least one thread operates on each link. In the last case we will need synchronized queues – and here we will also show how std::expected can be used again to create a flexible interface. Everyone is welcome!
