A calculation method for the simulation of the Eddy Current Testing (ECT) signal of multiple cracks is implemented on a general purpose video card. NVIDIA's parallel computing solution, the Compute Unified Device Architecture (CUDA) was used as a shell for the implementation on both hardware and software sides. Possibilities inherent in this technology are shown through an example and a detailed implementation focusing on data parallel execution is discussed. Different realizations of the same algorithm are inspected and a comparison from the view of efficiency is given.
