Explore parallelism on ranges in C++ through this conference talk from CppNow 2021. Delve into the challenges and possibilities of embedding execution policy mechanisms into range-based algorithms. Examine how HPX, a C++ Standard Library for Concurrency and Parallelism, proposes implementation strategies for range parallelization. Gain insights into algorithmic fusion, pipelining, and the potential performance impacts of parallelizing ranges. Learn about the speaker's perspective on whether the C++ community should push for range-based algorithm parallelization and understand the complexities involved in this powerful concept.
