WebHowever, Dhrystone numbers obtained under these conditions should be explicitly marked as such; "normal" Dhrystone results should be understood as results obtained following the ground rules listed above. In any case, for serious performance evaluation, users are advised to ask for code listings and to check them carefully. 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.
