The purpose of Amdahl&#x27;s 1967 paper was to dissuade customers that multiprocessors were cost-effective (read: more expensive for him to produce at Amdahl Corp). In a certain sense, he was correct. Ironically, however, that same paper is now the most quoted in the parallel processing literature. Moreover, he never wrote down the &quot;law&quot; that is now attributed to him---a marketing coup.
