Descripción
Sumario:[EN] The development of acoustic field simulation in real time for non destructive ultrasonic evaluation applications would be an useful tool for both the planning and evaluation of inspections in-situ. However, they are algorithms which require high computing power, not due to their complexity but because of the large number of points to be analysed, which limits their use to laboratory workstations for high performance. The parallelization resources currently available in computer systems, such as multicore processors and GPGPU techniques, are a very interesting chance for the development of such applications. This work analyses the parallelization model of both alternatives in order to develop a portable ultrasonic field simulation system for real-time. The changes for both algorithms are described, in order to adapt it to GPGPU philosophy and a estimation of the computational cost of both implementations is given.
