Intel VTune

There are multiple profilers available on UPPMAX. This page describes Intel VTune.

Intel VTune is a broad set of tools with a focus on performance improvement of Intel-compiled code.

Intel's performance analysis suite can probably answer any question you have about the performance of your code, including MPI and OpenMP code.

VTune is focused choosing optimizing techniques that will yield good results, whereas Amplifier is more broadly aimed at performance analysis.

In order to use VTune do the following:

module load intel-oneapi vtune

Making sure you have a graphical connection through SSH X-forwarding or ThinLinc, then run VTune graphically like this:
