"He initially expected the first winner to have a speedup close to ten times, and that it would be difficult to advance beyond that." I recall that when we wrote the Cm* book (Parallel Processing: the Cm* Experience), we routinely saw speedups in the 10-20 range. Though the book was c. 1987, most of it was written in 1983 and 1984. I will have to check once I get back to my office.

Oh, please display the equation in math mode. I'm not quite sure how to do this in Mediawiki, but I see enough math that I'm sure there's a way.

I suggest the following references for scaled speedup (I got them from scholar.google.com, searching for "Gustafson scaled speedup"):

  • For superlinear speedup* the first several hits for "superlinear speedup" in Google Scholar seem good. I would suggest reading the introduction & conclusions of the papers before delving into the details (which may not be necessary).
