I have often heard the HP snake machines described as "not superscalar" whereas the IBM RS/6000 are generally described as "superscalar." What is it in the architectures of these two machines that supports this distinction? What are the consequences for the kinds of codes that will run efficiently (particularly in terms of floating point performance)? (P.S. could somebody email me a definition of "little endian" vs. "big endian" ? Are RS6000's, Suns and Macintoshes "big endian"? What about i860? Is it a property of the chip, or of the OS?)
