We are happy to declare the Inria Continuous Integration service open today January 29, 2013. Starting from this web portal, you can create a project and then :

• obtain on demand (within a few minutes) a continuous integration tool (Jenkins) that is dedicated to your project,
• create and manage workers (build machines) with various 32/64 bits OS. Note that we are currently working on providing OS X workers to the platform.

Take a look at the on-line documentation (https://wiki.inria.fr/ciportal) for more information about this service.

If you want to know more on the continuous integration methodology, here is a very good post by Martin Fowler.
Note that in the Inria research centers the local SED is also available to talk with you about continuous integration.
Note that more than twenty selected projects beta-tested this service with various programming languages, build tools, test libraries, etc. Those experiments allowed us to populate the FAQ. Take time to read it, to contribute your experiments, and to discuss and share knowledge via the mailing list ci-community at inria dot fr or by contacting the support team.
