Help us help you

• Damien François (UCLouvain/CISM)

Room: Salle S08 <p>This second session explains what you, as a user, can do to "help us help you". Small details in the way you use the clusters can have a large impact on the cluster ecosystem in general and on the availability of the system administrators to help on specific and non-trivial problems in your jobs. </p> <table border="0" cellpadding="10px"> <tbody> <tr> <td> <p><strong>Contents:</strong></p> <ul> <li>Good CÉCI citizenship and user duties</li> <li>Tips for quick support from the admins</li> <li>Pre-requisite checklist</li> </ul> <p>&nbsp;</p> </td> <td> <p><strong>No prerequisite.</strong><br /> <strong>Prerequisite for</strong>: all the other sessions.&nbsp;</p> <p><strong>Type</strong>: Lecture<br /> <strong>Target audience</strong>: Everyone<br /> <strong>Must:&nbsp;</strong>This session is mandatory.</p> </td> </tr> </tbody> </table>

Introduction to linux and the command line

Room: Salle S08 <table border="0" cellpadding="10px"> <tbody> <tr> <td colspan="2"> <p>Often, the workflow for researchers is to acquire a piece of software, and either modify it, or wrap it in scripts, or simply install it on the clusters, or all of that at the same time, on many clusters.
