Intel performance analisys toolkit that can be used to identify bottlenecks in an application. The tool can be used to perform different types of analisys.
Important Note: for the hardware event-based sampling (EBS), the Intel VTune Profiler profiles your application using the counter overflow feature of the Performance Monitoring Unit (PMU), and the vtune sampling drivers need to be loaded. Ask superc@cineca.it to be authorized to access an environment with the drivers requesting the association of the qos_vtune QOS.
Once enabled to the use of the qos_vtune, you need to request it in your job together with the vtune constraint as follows:
#SBATCH --qos=qos_vtune (or -q qos_vtune)
#SBATCH --constraint=vtune (or -C vtune)
To start the analisys use the command line interface:
