VTune GUI on a devcloud machine

[Utku]

Hello,

I have several profiling results, which I want to examine  by using VTune GUI (as it provides a lot of options to examine -- which threads, what functions, what source lines, etc.), but I am not able to open VTune GUI on devcloud.  When I type "vtune-gui" on the terminal, I receive the following error:

vtune-gui: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

Can I use VTune GUI on the devcloud? If so, how?

Thank you very much,

Regards,

Utku

Hi,

Thanks for posting in Intel forums.

For running VTune on the DevCloud, note the following:

1)VTune can’t be used with a GUI. This is by design and not a bug.

2)The Intel DevCloud is a cluster with no windows subsystem – much like any other HPC cluster out there.

3)You can also use VTune APS “aps <command>” instead of the full vtune. This gives you a performance snapshot.

Another method is Vtune Webserver Interface.

For your information the web server interface helps you quickly get started with the tool since you do not need to install VTune Profiler as a desktop application on every client system. You can use the VTune Profiler Server to configure and control analysis on arbitrary target systems and view collected results.

To run via webserver follow the below steps:

1)Start Vtune Profiler Server

<vtune-install-dir>/bin64/vtune-backend (or) vtune-backend --web-port=8080

2)After running the above command you will get a URL.If you are running it for the first time then your URL will have a one-time token like below

Serving GUI at https://127.0.0.1:64880?one-time-token=0160852eeff593e0ab0a0f90991b4efa

3)You can open the URL in browser on your local machine. In devcloud, you may need to do two-way tunneling to open the URL. 

4)For two way tunneling , open a new prompt and tunnel to login node of the Devcloud using the below command

ssh -L 8880:localhost:8880 devcloud_proxy

Then, tunnel to compute node as 

ssh -L 8880:localhost:8880 s001-n058

Where,

devcloud_proxy :- Host name

8880 :- Port in which vtune web sever is running

s001-n058:- compute node in which your vtune web server has started

5)Set a passphrase in the Set Passphrase dialog box.

For further reference you can use the below link

Hope this helps!
