This article presents a short overview of current parallelization concepts, focusing on vectorization, OpenMP and MPI, to obtain parallelization at the stream, thread and process levels. Vectorization allows compilers and inter- preters to generate parallel code to perform the same operation over all the different elements of data arrays, and significantly improves code robust- ness and organization. OpenMP and MPI are the the most commonly used cross-platform solutions to obtain thread and process parallelism.
