WHY GPU IS USED

The Powerhouse of Parallel Processing

Imagine yourself standing at the starting line of a race, eager to sprint towards the finish. As the starter fires the gun, you take off, your muscles firing in unison, propelling you forward. Now, imagine if you had ten or even a hundred times more muscles, each capable of generating the same force. The acceleration would be astounding, wouldn’t it?

This analogy perfectly illustrates the essence of a Graphics Processing Unit (GPU). GPUs are specialized electronic circuits designed to accelerate the creation of images, videos, and other visually rich content. They excel at performing highly parallel operations, much like having an army of tiny workers simultaneously performing their tasks. In this article, we’ll delve into the realm of GPUs, understanding their significance and exploring the diverse applications where they shine.

The Architecture of Parallelism

The key to a GPU’s prowess lies in its unique architecture. Unlike traditional CPUs (Central Processing Units), which focus on sequential processing, GPUs are designed for parallelism. They comprise thousands of smaller processing cores, each capable of handling multiple tasks concurrently. Imagine a team of chefs working in a busy kitchen, each preparing different dishes simultaneously. The GPU operates in much the same way, efficiently juggling multiple calculations at once.

CUDA Cores: The Workhorses of Parallelism

At the heart of a GPU are CUDA cores, specialized processing units designed to handle complex mathematical calculations. CUDA (Compute Unified Device Architecture) is a parallel computing platform and programming model that enables developers to harness the power of GPUs for general-purpose computing tasks. CUDA cores are particularly adept at handling data-intensive tasks, such as matrix multiplication and other linear algebra operations, which are prevalent in graphics processing.

The Applications of GPU Computing

GPUs have transcended their traditional role in computer graphics and found widespread applications across various domains. Let’s explore some of the key areas where GPUs excel:
