# Poisson problem The Poisson problem is a simple partial differentual equation (PDE) that is at the core of many applications. The example is useful for desccribing the features of MPI/OpenMP/CUDA/OpenACC that can be used in solving partial differential equations and other problems that involve decomposition across many processes.
