N-body Simulations Using the GPU

获奖作品摘要

My project is built around the idea to use the graphics card as a method of accelerating the simulation of physical systems in the form of N-body systems. This vastly reduces the high amount of time required for simulating these systems, allowing me to create complex simulations of physical systems at home that are otherwise difficult to observe in real-world experiments. In many cases, the graphics card can replace huge and cost intensive computer clusters. With a specialized software I wrote in C++ and accelerated with CUDA, I was able to simulate the collision of galaxies and their formation, the process of crystallization and the behavior of Lab-on-a-Chip devices in the field of nanofluidics, addressing the issue of controlling the liquid flow through nano pipes, at home. To show that my simulations represent the behavior of the real world, I also simulated known problems and compared my results with real-world experiments. I am able to use the graphics card as a powerful tool for accelerating computer simulations and to drastically lower the cost and time needed to run N-body simulations, thus increasing efficiency. I was also able to apply the concept of N-body systems onto many different physical systems, essentially broadening the range of application for N-body systems.

Additionally, I created a program that allows other people to create and simulate their own N-body systems, making the process of creating N-body simulations faster and available to everyone, without the need to write specialized code to control the graphics card first.

高中生科研学术活动 英特尔 Intel ISEF 简介

英特尔国际科学与工程大奖赛，简称 "ISEF"，由美国 Society for Science and the Public（科学和公共服务协会）主办，英特尔公司冠名赞助，是全球规模最大、等级最高的中学生的科研科创赛事。ISEF 的学术活动学科包括了所有数学、自然科学、工程的全部领域和部分社会科学。ISEF 素有全球青少年科学学术活动的“世界杯”之美誉，旨在鼓励学生团队协作，开拓创新，长期专一深入地研究自己感兴趣的课题。

学科简介：物理与天文学 Physics and Astronomy

Physics is the science of matter and energy and of interactions between the two. Astronomy is the study of anything in the universe beyond the Earth.

Subcategories:

Atomic, Molecular, and Optical Physics (AMO): The study of atoms, simple molecules, electrons, light, and their interactions.  Projects studying non-solid state lasers and masers also belong in this subcategory.

Astronomy and Cosmology (AST): The study of space,  the universe as a whole, including its origins and evolution, the physical properties of objects in space and computational astronomy.

Biological Physics (BIP): The study of the physics of biological processes and systems.

Condensed Matter and Materials (MAT): The study of the properties of solids and liquids. Topics such as superconductivity, semi-conductors, complex fluids, and thin films are studied.

Mechanics (MEC): Classical physics and mechanics, including the macroscopic study of forces, vibrations and flows; on solid, liquid and gaseous materials. Projects studying aerodynamics or hydrodynamics also belong in this subcategory.

Nuclear and Particle Physics (NUC): The study of the physical properties of the atomic nucleus and of fundamental particles and the forces of their interaction. Projects developing particle detectors also belong in this subcategory.

Theoretical, Computational, and Quantum Physics (THE): The study of nature, phenomena and the laws of physics employing mathematical or computational methods rather than experimental processes.

Other (OTH): Studies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.
