For some time now already, OAR has supported working conjointly as a provider of workers for several meta jobs and resources managers:

• Dask-jobqueue (see the dedicated documentation on Grid'5000).

• Nypipe (see the dedicated documentation on Grid'5000)
• Submitit (see the dedicated documentation on Grid'5000)

OAR also cooperates very well with GNU Parallel (see a full set of examples on Grid'5000).

Our documentation is not in good shape, and sometimes outdated. We added some missing commands to it (e.g. oarwalltime, oarprint) so that they get to be known. Please mind reading the manual pages of the OAR commands (with man !), which are generally more up to date. Also your help would be very welcome: OAR is an open-source project, feel free to open an account on this website and request a contributor access.

The OAR team lately worked on providing environments to help demonstrate and test OAR. Those environments make use of virtual machines, using vagrant/virtualbox and docker.

Those tools could be of very good help for testing OAR before considering installing a new version on real clusters. oar-vagrant also shows a basic setup of OAR in its provision script, which is kind of a self documentation.

Please feel free to give feedback on those tools.

OAR has a new website ! We choose to use a lighter framework for our web site, unifying the wiki site and the main site in a single dokuwiki. Some parts of the site are still to move/adapt from the old website.

Thanks to C. Pernet for the nice panorama of Belledonne, which OAR looks over.

The first stable release of the 2.5.x series is out.

A lot of work has been done between the branches 2.4.x and 2.5.x. Among them:

A lot of improvements and optimization of the RestFull API

OAR 2.5 provides a Restfull API to submit/query/administrate the batch scheduler. The API now implements pagination and uses FastCGI for better performance.

A better installation procedure

The source code has been reorganized and the installation scripts have been improved to ease both the installation process and the packaging maintenance. OAR can be now installed on the Debian/Redhat like operating systems with the same procedure. And supporting another system should be easy (provided that the system fullfill the needed dependencies).
