Amdahl's Law - Relation To Gustafson's Law

Relation To Gustafson's Law

John L. Gustafson pointed out in 1988 what is now known as Gustafson's Law: people typically are not interested in solving a fixed problem in the shortest possible period of time, as Amdahl's Law describes, but rather in solving the largest possible problem (e.g., the most accurate possible approximation) in a fixed "reasonable" amount of time. If the non-parallelizable portion of the problem is fixed, or grows very slowly with problem size (e.g., O(log n)), then additional processors can increase the possible problem size without limit.

Famous quotes containing the words relation to, relation and/or law:

    Whoever has a keen eye for profits, is blind in relation to his craft.
    Sophocles (497–406/5 B.C.)

    The instincts of the ant are very unimportant, considered as the ant’s; but the moment a ray of relation is seen to extend from it to man, and the little drudge is seen to be a monitor, a little body with a mighty heart, then all its habits, even that said to be recently observed, that it never sleeps, become sublime.
    Ralph Waldo Emerson (1803–1882)

    Law without education is a dead letter. With education the needed law follows without effort and, of course, with power to execute itself; indeed, it seems to execute itself.
    Rutherford Birchard Hayes (1822–1893)
