Asynchronous Tasks and Scalar Product Calculation in C++

Writing fast, responsive software requires a solid understanding of how to run operations in parallel. This text-based course guides you through the foundational concepts of concurrency in modern C++, focusing on how to distribute heavy mathematical workloads across multiple CPU cores. You will start with the core terminology of multithreading, learn how asynchronous execution works, and then build up to practical, high-performance calculations. By the end of this course, you will be able to write safe, non-blocking C++ code that efficiently computes scalar products and processes large datasets. What you will learn: Understand the difference between synchronous execution and asynchronous tasks; Configure asynchronous operations using std::async and retrieve results with futures; Generate and manage large vectors of random data using modern C++ standard library features; Implement a parallelized scalar product calculation to maximize CPU utilization; Practice safe resource management and handle exceptions in concurrent code. The course begins with essential concepts of threads, tasks, and futures before moving step-by-step into memory layout, vector operations, and performance tuning. This course is designed for beginner-to-intermediate C++ developers who want to transition from single-threaded programming to modern concurrent systems, with no prior multithreading experience required.
