Dear Users,</p>
<p>The scheduled maintenance operations on Marconi have been completed and the<br />
cluster is now back to production.</p>
<p>Slurm scheduler was updated to version 20.02.06, and the new feature "vtune"<br />
was defined for requesting the assigned nodes to load the sampling (sep5)<br />
drivers, enabling the hardware event-based sampling<br /><a href="https://software.intel.com/content/www/us/en/develop/documentation/vtune-help/top/analyze-performance/hardware-event-based-sampling-collection.html#hardware-event-based-sampling-collection">https://software.intel.com/content/www/us/en/develop/documentation/vtune...</a><br />
(EBS). In this mode, Intel VTune Profiler profiles your application using the<br />
counter overflow feature of the Performance Monitoring Unit (PMU).</p>
<p>This configuration replaces the previous setting, where the sep5 drivers were<br />
automatically loaded on all nodes at boot time. If you need to exploit the<br />
hardware EBS, please request the vtune feature in your job script as follows:</p>
<p>#SBATCH -C vtune</p>
<p>Best regards,</p>
