Multiple GPU Fluid Simulation

This was the final project for my CS240A - Applied Parallel Computing course (taught by Prof. John R. Gilbert).

• Team: Donghao Ren, Junsheng Guo

Introduction

We implemented a Multiple GPU fluid simulation program that runs on Triton or Lonestar machines. We parallelized the Smooth Particle Hydrodynamics algorithm first with a single GPU and then with multiple GPUs. The program is written in CUDA and MPI.
