MARCONI: maintenance completed and update on Intel Vtune

Dear Users,

The scheduled maintenance operations on Marconi have been completed and the cluster is now back to production.

Slurm scheduler was updated to version 20.02.06, and the new feature "vtune" was defined for requesting the assigned nodes to load the sampling (sep5) drivers, enabling the hardware event-based sampling (EBS). In this mode, Intel VTune Profiler profiles your application using the counter overflow feature of the Performance Monitoring Unit (PMU).

This configuration replaces the previous setting, where the sep5 drivers were automatically loaded on all nodes at boot time. If you need to exploit the hardware EBS, please request the vtune feature in your job script as follows:

#SBATCH -C vtune

Best regards,
