Paper Abstract

This paper presents an ultrasonic field simulation software, dedicated to Non Destructive Testing, aiming at interactivity. This work relies on Civa Software semi-analytical model. By restricting its scope to homogeneous isotropic specimens with simple geometry and half-skip modes, an almost completely regular algorithm, well suited to modern hardware, can be derived. The performance of three implementations on multicore SIMD general purpose processors (GPP), manycore accelerators (MIC) and graphical processing units (GPU) over a set of 18 realistic configurations (a standard one plus 17 variations) are presented and analysed. For GPP and the GPU, interactive performances with almost 30 fps have been reached on the standard configuration. This is, to our knowledge, the very first time for a NDT ultrasonic field simulation software.
