Dhrystone is a synthetic computing benchmark program developed in 1984 by Reinhold P. Weicker intended to be representative of system (integer) programming. The Dhrystone grew to become representative of general processor (CPU) performance. The name "Dhrystone" is a pun on a different benchmark algorithm called Whetstone (pun explained: whet-stone = wet-stone dhry-stone = dry-stone), which emphasizes floating point performance. WebFor example some companies might publish a score for Dhrystone 1.1 running on its latest processor core. Dhrystone 1.1 has been obsolete for many years and Dhrystone 1.1 scores are not comparable to Dhrystone 2.1 scores (the current version). But because there is no industry-standard group to manage the process and rules, and
