Contest Management System



CMS, or Contest Management System, is a distributed system for running and (to some extent) organizing a programming contest.

CMS has been designed to be general and to handle many different types of contests, tasks, scorings, etc. Nonetheless, CMS has been explicitly build to be used in the 2012 International Olympiad in Informatics, held in September 2012 in Italy.


For end-users it's best to download the latest stable version of CMS, which can be found already packaged at

This git repository, which contains the development version in its master branch, is intended for developers and everyone interested in contributing or just curious to see how the code works and wanting to hack on it.

Please note that since the sandbox is contained in a git submodule you should append --recursive to the standard git clone command to obtain it. Or, if you have already cloned CMS, simply run the following command from inside the repository:

git submodule update --init


The complete CMS documentation is at

The mailing list for announcements, user support and general discussion is You can subscribe at So far, it is an extremely low traffic mailing list.

The mailing list for development discussion (to submit feedback, proposals and critics, get opinions and reviews, etc.) is You can subscribe at

Please don't use these mailing lists for bug reports. File them on github instead.

To help with the troubleshooting, you can collect the complete log files that are placed in /var/local/log/cms/ (if CMS was running installed) or in ./log (if it was running from the local copy).


CMS has been used in several official and unofficial contests. Please find an updated list at

If you used CMS for a contest, selection, or a similar event, and want to publicize this information, we would be more than happy to hear from you and add it to that list.
