Simulation of pulse propagation in nonlinear optical fibers using GPUs

We present an implementation in graphical processing units of a numerical algorithm for the simulation of the nonlinear propagation of pulses in optical fibers. The implementation uses NVidia's cuFFT library to perform the large number of FFTs calculations required and parallelizes all vector sums and products. We show up to 50 × speedups as compared to a single-core implementation on a PC.
