## Usage
To profile an application with VTune Profiler, special kernel modules need to be loaded. The modules are not loaded on the login nodes, thus direct profiling on login nodes is not possible. By default, the kernel modules are not loaded on compute nodes either. In order to have the modules loaded, you need to specify the `vtune=version` PBS resource at job submit. The version is the same as for the environment module. For example, to use VTune/2020_update2-GCC:

After that, you can verify that the modules `sep*`, `pax`, and `vtsspp` are present in the kernel:
```console
login@cn191:~$ lsmod | grep -e sep -e pax -e vtsspp
$ lsmod | grep -e sep -e pax -e vtsspp
