Q: What’s the key difference between concurrency and parallelism?
A: Concurrency is about structuring a program to handle multiple tasks simultaneously, while parallelism is about executing multiple computations at the exact same time, typically on multiple CPU cores.
Fearless Concurrency with Channels and Message Passing
Mastering concurrency and parallelism tricks is key to unlocking high-performance software. It’s about writing code that does multiple things seemingly at once (concurrency) or truly simultaneously across CPU cores (parallelism). Clever techniques like thread pools, non-blocking algorithms, and efficient task scheduling prevent bottlenecks and keep your application responsive. These advanced programming strategies are essential for building scalable systems that can handle massive workloads without breaking a sweat.
