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. Later the CPU89 benchmark suite from the Standard Performance Evaluation Corporation[citation needed], today known as the "SPECint" suite was introduced, but SPEC programs are quite expensive whereas Dhrystone is free, therefore Dhrystone remains popular.
The name "Dhrystone" is a pun on a different benchmark algorithm called Whetstone.
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.
Project Description
Description should be no longer than a paragraph. Include links to any relevant on-line resources. For example, http://google.com or MDC.
Project Leader(s)
Name(s) of primary people working on the project. If you want to join a project as leader, discuss with other leaders first. Include links to personal pages within wiki
Project Contributor(s)
Name(s) of people casually working on the project, or who have contributed significant help. Include links to personal pages within wiki
NOTE: only Project Leader(s) should add names here. You can’t add your own name to the Contributor list.
Project Details
Provides more depth than the Project Description. This is the place for technical discussions, project specs, or other details. If this gets very long, you might consider breaking this part into multiple pages and linking to them.
Project Plan
Goals for each release:
- 0.1
- 0.2
- 0.3
Project News
This is where your regular updates will go. In these you should discuss the status or your work, your interactions with other members of the community (e.g., Seneca and Mozilla), problems you have encountered, etc.
Put detailed technical information into the Project Details page (i.e., update it as you go), and save this section for news about participation in the project.
