What is Multiprocessing?. The use of more than one Central Processing Unit (CPU) with a single computer system, to perform tasks.. In multiprocessing most if not all CPUs perform the same function, however some may be reserved for a different function.. Sameera K. Abeykoon. Meifeng Lin. Kerstin Kleese van Dam. Talk outline.
