Quick anatomy of a process

Processes are normally more complex than threads. In general, they contain a main thread, but can also be multithreaded if you choose. They are capable of spawning multiple sub-threads, each of which contains its own set of registers and a stack. Each process provides all the resources that the computer needs in order to execute the program.

Similarly to using multiple threads, we can design our code to take advantage of a multiprocessing design. Multiple processes are likely to run over multiple cores, therefore with multiprocessing, you can truly parallelize computation. Their memory footprints, though, are slightly heavier than those of threads, and another drawback to using multiple processes is that inter-process ...
