In today's fast-paced digital world, the need for efficient and powerful computing solutions has never been greater. Parallel processing, a technique that allows multiple tasks to be executed simultaneously, has emerged as a game-changer in the realm of computing. This article delves into the concept of parallel processing, its significance, and its applications across various industries.
What is Parallel Processing?
Parallel processing is the act of dividing a large task into smaller sub-tasks and executing them concurrently on multiple processors or cores. This approach significantly reduces the time required to complete complex computations, making it an essential component in high-performance computing (HPC) systems.
