Introduction to Program Optimization for Multi-Core Systems

Modern computers have multiple processing cores, yet many programs only run on a single thread, leaving massive performance potential untapped. Understanding how hardware executes your code is the key to writing truly fast software. This course guides you from the fundamental architecture of modern processors to core techniques for parallel programming and memory optimization. You will learn to write clean, concurrent code that utilizes every processor core efficiently without causing race conditions or memory bottlenecks. What you'll learn: Understand how modern multi-core processors manage memory hierarchies, caches, and instruction execution; Identify and eliminate common concurrency issues like race conditions, deadlocks, and false sharing; Apply cache-friendly data structures to maximize data locality and minimize memory latency; Implement efficient multi-threading patterns using modern task-based and thread-pool approaches; Analyze program performance bottlenecks using profiling concepts and execution analysis; Practice optimizing algorithms for parallel execution through structured text-based code walk-throughs. The course begins with essential hardware concepts and memory hierarchies before moving into practical multi-threading strategies and optimization techniques. You will read clear explanations and examine optimized code examples designed to build your system-level thinking. This course is designed for beginner to intermediate programmers who want to transition from writing single-threaded code to building high-performance parallel applications, with no prior experience in hardware design required.
