A GPU approach to the simulation of spatio-temporal dynamics in ultrasonic resonators

Abstract

In this work we present the implementation of an application to simulate the evolution of pressure and temperature inside a cavity when acoustic energy is injected, a physical system currently under intensive research. The particular features of the equations of the model makes the simulation problem very stiff and time consuming. However, intrinsic parallelism makes the application suitable for implementation in GPUs providing the researchers with a very useful tool to study the problem at a very reasonable price. In our experiments the problem was solved in less than half the time required by CPUs. © 2010 Springer-Verlag Berlin Heidelberg.
