This example solves a 2nd order wave equation: utt = uxx + uyy, with u = 0 on the boundaries. It uses a 2nd order central finite difference in time and a Chebyshev spectral method in space (using FFT). It compares to running the same algorithm on the GPU using gpu-arrays and built-in functions available for the GPU.
