Coming from C background, there is OpenMP, with with a bunch of #pragma omp parallel for (and others) can easily turn suitable processes into data-parallel ones (for example lots of image processing could be sped up this way). On top of this, if you don't link with OpenMP it stays the old way (serializable).
