Dhrystone         
<benchmark> A short synthetic benchmark program by Reinhold Weicker <weicker.muc@sni.de>, <weicker.muc@sni-usa.com>, intended to be representative of system (integer) programming. It is available in ADA, Pascal and C. The current version is Dhrystone 2.1. The author says, "Relying on MIPS V1.1 (the result of V1.1) numbers can be hazardous to your professional health." Due to its small size, the memory system outside the cache is not tested. Compilers can too easily optimise for Dhrystone. String operations are somewhat over-represented.

Dhrystone

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.

With Dhrystone, Weicker gathered meta-data from a broad range of software, including programs written in FORTRAN, PL/1, SAL, ALGOL 68, and Pascal. He then characterized these programs in terms of various common constructs: procedure calls, pointer indirections, assignments, etc. From this he wrote the Dhrystone benchmark to correspond to a representative mix. Dhrystone was published in Ada, with the C version for Unix developed by Rick Richardson ("version 1.1") greatly contributing to its popularity.
