UIUC Projects

Operating System Design (CS321)

My final project was a user level threads package. Here is a link to my paper and the software I wrote.

Introduction to Numerical Methods (CS450)

My project was a liquid Argon simulation implemented pretty much straight out of Frenkel and Smit. This was the first of my classes taught by Prof. Heath.

NA Seminar (CS491/591)

This is a regular seminar that the NA group has every semester, it is instructed by Prof. Heath. The purpose of this seminar is to get us used to presenting in front of a group, as well as presenting our research in a relatively informal setting.

• Presentation 2/2/04 Title: Viscoelastic Flow Modeling and Generative Programming
• Presentation 4/6/05 Title: The WHAM Method for Calculating the Potential of Mean Force

Parallel Numerical Algorithms (CS454)

This class was also taught by Prof. Heath. The final project was a modification of the liquid argon simulation, but to run in parallel. I implemented two methods, first being a simple modification of the serial code to be a redundant data method, the second is a more complex spatial decomposition method. A link to the resulting writeup is below

Advanced Finite Elements (TAM574/CSE517)

For this class the project for everyone was to implement a 1d spacetime discontinuous Galerkin FEM for linear elastodynamics (seems complicated!). This is where I discovered both the difficulties of differential forms and discontinuous Galerkin methods. Here is the resulting paper

Spectral Element Methods/High order FEM (CS598LO)

The instructor for this class was Luke Olson. For this project I investigated the Poisson Boltzmann problem and various difficulties associated with it. I had a very hard time dealing with the discontinuous Galerkin formulation used here. This was extraordinarily difficult for me from a software perspective, and also very frustrating, I'm sure you'll get a flavor of this from reading the paper

Iterative and Multigrid Methods (CS550)

Once again Luke Olson was the instructor. For this project I considered geometric multigrid for adaptively refined meshes (AMR). In particular I looked at the multilevel adaptive technique (MLAT). This was the first MG algorithm used for AMR meshes. It certainly has weaknesses. However, the largest obstacle was implementing the data structures associated with AMR. Even the limited implementation done for this project proved to be difficult (though I only had 2 weeks).
