N-body Simulations Using the GPU

獲獎(jiǎng)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.

高中生科研學(xué)術(shù)活動(dòng) 英特爾 Intel ISEF 簡介

英特爾國際科學(xué)與工程大獎(jiǎng)賽，簡稱 "ISEF"，由美國 Society for Science and the Public（科學(xué)和公共服務(wù)協(xié)會(huì)）主辦，英特爾公司冠名贊助，是全球規(guī)模最大、等級最高的中學(xué)生的科研科創(chuàng)賽事。ISEF 的學(xué)術(shù)活動(dòng)學(xué)科包括了所有數(shù)學(xué)、自然科學(xué)、工程的全部領(lǐng)域和部分社會(huì)科學(xué)。ISEF 素有全球青少年科學(xué)學(xué)術(shù)活動(dòng)的“世界杯”之美譽(yù)，旨在鼓勵(lì)學(xué)生團(tuán)隊(duì)協(xié)作，開拓創(chuàng)新，長期專一深入地研究自己感興趣的課題。

學(xué)科簡介：物理與天文學(xué) 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.
