CUDAEASY is a GPU accelerated program that solves the evolution of interacting scalar fields in an expanding universe. The implementation is done in NVIDIA's CUDA. The program can achieve speedups between one and two orders of magnitude depending on the used software and hardware. The program has been written in the spirit of LATTICEEASY and users of the aforementioned program should find it relatively easy to start using CUDAEASY in lattice simulations.
