High-Performance Physics Engine Wiki

Welcome to the Wiki for the High-Performance Physics Engine, a research-driven project focused on high-performance computing (HPC), numerical simulation, and physical modeling.

This Wiki is structured to provide both theoretical foundations and detailed implementation insights. It is intended for researchers, developers, and anyone interested in the mechanics of custom physics engine design using modern computing tools.

Structure

This Wiki is divided into two primary sections:

Mathematical Foundations

This section covers the mathematical models, derivations, and numerical methods that underpin the engine. It includes:

• Formal derivations of physical laws used in simulation
• Reformulation of scalar systems into matrix operations
• Discussions of numerical integration techniques and stability
• Analytical context for optimization choices

Code and Implementation

This section explores the design and structure of the codebase, including details on:

• How C++, CUDA, and Fortran are used in coordination
• Performance-focused implementation patterns
• GPU offloading strategies and memory considerations
• Modular design and build configuration using CMake

About This Project

The High-Performance Physics Engine is an evolving research project designed to:

• Explore computational physics through hands-on derivation and implementation
• Develop efficient, matrix-based simulations suited to GPU execution
• Study hybrid architectures using CPU (Fortran) and GPU (CUDA) processing

The engine avoids prebuilt simulation libraries in favor of direct control and experimentation. Mathematical derivations are done from first principles and reflected directly in the code structure.

For an overview of the project, see the main README.

Additional sections will be added as development progresses. For questions, feedback, or research discussion, please reach out via the main repository.
