GPGPU: Basic Concepts and Usage of GPU Computing
What is GPGPU?
GPGPU, or General-Purpose computing on Graphics Processing Units, is a technology that enables the usage of GPU (Graphics Processing Unit) for tasks other than just rendering graphics. Historically, GPUs were designed specifically for visual computing, but with advancements in hardware and software, they can now be utilized for a wide range of general-purpose computations.
Basic Concepts:
GPU computing leverages the massively parallel architecture of GPUs to perform computations in a highly efficient manner. GPUs consist of thousands of cores, each capable of performing multiple tasks simultaneously. These cores work in parallel, allowing for high-speed data processing and parallel execution of tasks.
Usage of GPU Computing:
GPU computing has found significant applications in various fields, including but not limited to:
- Data Science and Machine Learning: GPUs excel in performing computationally intensive tasks required in data analysis, pattern recognition, deep learning, and training of neural networks. They can significantly accelerate training and inference processes, allowing for faster model development and improved accuracy.
