1.2.3 Uniprocessor and multiprocessor
The terms uniprocessor and multiprocessor are fairly straightforward, but let's define them just to make sure there's no confusion. By uniprocessor, I mean a computer with a single programmer-visible execution unit (processor). A single general-purpose processor with superscalar processing, or vector processors, or other math or I/O coprocessors is still usually considered a uniprocessor.
By multiprocessor, I mean a computer with more than one processor sharing a common instruction set and access to the same physical memory. While the processors need not have equal access to all physical memory, it should be possible for any processor to gain access to most memory. A "massively parallel processor" (MPP) may or may not qualify as a multiprocessor for the purposes of this book. Many MPP systems do qualify, because they provide access to all physical memory from every processor, even though the access times may vary widely.
