Executive Summary

General Purpose GPU computing, or GPGPU, is the use of a GPU (Graphics Processing Unit) to do general purpose scientific and engineering computing. The model for GPU computing is to use a CPU and GPU together in a heterogeneous co-processing computing platform. The sequential part of the application runs on the CPU and the computationally-intensive part is accelerated by the GPU. From the users perspective, the application just runs faster because it is using the high-performance of the GPU to boost performance. The authors have applied this technique to some sub-problems that form part of an ice-floe simulation problem and conducted an experiment to measure the performance of the GPU with respect to the CPU.
