cache miss and floating point operation

Salve a tutti,

sono interessato a valutare i cache miss e il numero di operazioni floating point con riferimento ad un programma MPI.

Da riga di comando ho provato:

mpirun -n 4 -l amplxe-cl -result-dir XXX -collect hotspots eseguibile

Il tipo di analisi "HOTSPOTS" è sufficiente per ottenere quanto desiderato?

Se sì. una volta aperti i risultati usando l'interfaccia grafica (amplxe-gui), dove sono reperibili le informazioni di cui sopra?

Se no, che comando è necessario utilizzare?

Problem with installing evaluation license


we would like to try out Intel VTune and have downloaded the LINUX version and tried the installation without root access.

The installation guide says the followings:

> Execute the ./ script file (available at the top level in the extracted contents) as a root user. Activation is required.

However it says later "The install can be run as a non-root user, but in this case not all collectors will be available to the user", when I try to install it as an evaluation version the following comes up:

VTune GUI Unable to initialize gtk

Hi guys,

I just started exploring VTune trying to identify the hotspot in my program. After I did the "source", I typed "amplxe-gui", but it gave me:

"Error: Unable to initialize gtk, is DISPLAY set properly?"

I searched this problem for a long time but could not find anything related. Can any one help me?

Thanks a lot!


How to export a result of an analyze to readable format?

Hi everyboby,

I'm new here in the forum so i would like to apologize if my post isn't in accordance with the rules.

I'm working on a scientífic paper on the university and need scan a code regardind the amount and tipe of branchs and export a log file that is readble nd contains the base adress and the target adress of each branch, and it was taken or not.

I started using the Vtune a short time and I couldn't find a way to do what i need.

Reversed View


I've just downloaded the evaluation version of VTune_Amplifier_XE_2015_update2 and tried using it for performance evaluation.

The performance evaluation has succeeded, but the problem is that I see all the text reversed (from right to left), hence I cannot understand the names of functions etc. Actually all the view panel is reversed.

Can anyone give me an advice about how to solve this problem?


vtune cannot connect to mic


I'm trying to use Vtune on a host with Xeon Phi cards. I have Intel Xeon Phi coprocessor (native) as the target system and 0(mic0) as the card number in the amplxe-gui. When I try to do an analysis, vtune complains:

ssh: Could not resolve hostname 0(mic0): Name or service not known

(see attached screen shot for vtune version info and the error message)

Vtune 2015 Update 2 stopped working on some VS2010 solutions


I've just upgraded to Update 2 (from update 1) running inside VS2010.  On some C++ solutions I'm finding the New Analysis and Project properties greyed out and I can run any analysis on those projects.  The solutions still have the the results files from the previous version and I can open those fine.  On other solutions I've checked the New Analysis button isn't greyed out and I can run those without problem.
