I am trying to relaunch the slaves for Moose (https://ci.inria.fr/moose), but I am somehow unable to accomplish that. Could you take a look at this as well?
Done!
If you want to do start/stop slaves by yourself, you need to go to https://ci.inria.fr/project/moose/slaves#. To speed-up things, then go to jenkins / manage Jenkins / manage nodes and click on a slave and finally click on "Launch slave agent"
