About the comments on Rocks and the Slurm roll... in my experiences,<br>
rocks 7 is very good and the unofficial slurm roll provided by Werner<br>
is also very good. It is worth to give them a try. Although I had some<br>
experiences with manual slurm installation on an ubuntu cluster some<br>
years ago, the automatic installation of the roll was very nice<br>
indeed! All the commands and configurations can be extracted from the<br>
roll. So there is no dark point about that. Limited issues about<br>
slurm, e.g. installation, are directly related to Werner. Most of the<br>
other question are related to the slurm itself. For example accounting<br>
and other things.<br>
<br>
