Order (or just read more about) SMP and Caching from Amazon.com
Everything you ever wanted to know about SMP, and more than I ever wanted to know about caches.
This is another book I found useful while studying for Sun exams. Beyond that, though, it's a great introduction to the problems of multiprocessor machines.
More than half the book deals with cacheing issues, which is to be expected. There is a small (very small) review of Unix internals, and then it dives right into caches: virtual, physical, virtual with keys and on it goes. After that, 150 pages or so on multiprocessing, and then back into caches, this time from a multiiprocessor perspective.
Worth reading even if you only want a better understanding of
multiprocessing. With the coming advent of clusters, it's
worthwhile to understand this as a comparison point.

UNIX does not allow path names to be prefixed by a drive name or number; that would be precisely the kind of device dependence that operating systems ought to eliminate. (Andrew S. Tanenbaum)
