Modern C++ Concurrency: Get the most out of any machine

Single Threaded Summation: Addition with std::accumulate

Explore how to calculate the sum of a vector using std::accumulate in a single-threaded context. Understand performance differences across platforms and evaluate the costs of using locks and atomic operations without contention.
