> Software compilation Well, no. Software compilation does not work massively parallel. Maybe parts of the optimization pipeline, but compilation of 1000 unit program (assuming your language of choice even has separate compilation) does normally require to put the units into a dependency graph (see OCaml, for instance), or puts most of the effort into the inherently serial tasks like preprocessing and linking (C++).
