Abstract
  • The reaction of fluid or gas flowing around an obstacle is a common engineering problem. Computer simulations are often used to measure and visualize the physical processes involved. In this report, we will discuss a parallel implementation of a simulation using the Smooth Particle Hydrodynamics (SPH) approach to fluid flow. We will discuss the design decisions made during development, problems encountered during implementation, and parallel performance issues. Section 2 will introduce the fill.id flow problem, the SPH technique, and our project motivations. Section 3 will discuss our first O(N²) serial version of the simulator. Section 4 covers our improved O(N) grid-based serial version. In section 5, we will develop the MPI parallel simulation, discuss debugging issues and provide results from our performance tuning. Section 6 describes our Java application client used to control the simulation. In section 7, the Java/C++ socket library used for communication with the client is discussed. We will conclude in section 8 with an evaluation of oar successes and failures during the project and look at future directions for this work.
