Study Notes

Understanding GPUs: Functions and Advantages

Graphical Processing Units (GPUs) serve as co-processors, specialized processors enhancing overall computer speed by executing tasks concurrently with the CPU.
CPU vs. GPU Characteristics:
- Design Goal: CPUs focus on general-purpose processing, while GPUs are optimized for specialized parallel tasks.
- Number of Cores: CPUs have fewer, more powerful cores; GPUs possess thousands of less powerful cores.
- Processing Style: CPUs excel in complex operations on small datasets; GPUs thrive in performing simple operations on large datasets.
- Example Uses: CPUs handle general computing tasks (e.g., web browsing, word processing), whereas GPUs are used for graphics rendering, scientific simulations, machine learning, and data analysis.

How GPUs Operate

GPUs process multiple parallel data streams simultaneously, making them ideal for:
- SIMD (Single Instruction, Multiple Data) operations, where the same operation is executed on multiple data points at once.
- Handling matrix and vector operations critical for graphics rendering and scientific simulations.

3D Wireframe Rendering Steps

Steps involved in rendering a 3D wireframe of a mountain landscape include:
- Assigning x, y, and z coordinates to image segments.
- Applying textures or patterns to segments.
- Setting light source parameters including angle and brightness.
- Selecting a camera source for the image.
- Performing arithmetic calculations based on assigned coordinates.
- Executing RGB calculations for each pixel to ensure accurate color representation.
- Generating a 2D visual output of the 3D scene for display.

Benefits of GPUs for Parallel Processing

Despite CPUs' ability to perform single operations quickly, GPUs can execute many operations in a shorter timeframe due to their parallel processing design.

General-Purpose Computing on GPUs (GPGPU)

Since 2006, GPUs have expanded beyond graphics, being utilized for:
- Oil exploration modeling.
- Weather modeling.
- Machine learning applications.
- Linear algebra computations.
- Extensive statistical analysis.
- Stock option predictions.
- Gravitational field theory research.
