Those tools could be of very good help for testing OAR before considering installing a new version on real clusters. [[wiki: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. --- //Pierre Neyron for the OAR-team 2014/09/11// {{ :oar_sc13_1200.png?200|}} ===== OAR at SuperComputing 2013 ==== Please visit [[http://inriasc2013.tumblr.com/|Inria's booth]] at [[http://sc13.supercomputing.org/|SC13]] next week in Denver, Colorado.
