Multiprocessing: multiple CPU, like CMP, SMP, etc.
Multithreading: One CPU but probably with more threading HW support, like multiple Register files and PC's.
Superscalar: HW supported dynamic instruction issue and branch predication
VLIW: Software (compiler) supported multiple instruction issue and BP
ccNUMA SMP: symmetrical multiprocessing. OS could be running on any of multiple CPUs with the help of "resource locker". cc means cache coherence and each CPU has its own memory banks (NUMA).
