Help with getting started with Vtune

I am using the non-commercial version of Vtune on a Nehalem processor Linux cluster. And following the Intel instruction (http://www.rzg.mpg.de/from_external/intel/vtune/doc/Getting_Started.pdf)
to test the Vtune installation and to do some profiling.

When I launch vtlec and execute the instruction for the first example, gsexample2a, I am not able to see the data for gsexample2a (ProcessBuffer, Store2Load, GenDenomals,..).

I properly added the tuning activity for gsexample2a and Vtune started to create the analyses. But I can only see the following on the process pane for sampling activity:

Tue Mar 17 08:06:49 2009 127.0.0.1 (Run 0) The processor PMU configuration file: pmn.xml
Tue Mar 17 08:06:49 2009 127.0.0.1 (Run 0) Collection for the following event(s) is being performed:
Tue Mar 17 08:06:49 2009 127.0.0.1 (Run 0) CPU_CLK_UNHALTED.THREAD, INST_RETIRED.ANY.
Tue Mar 17 08:06:59 2009 127.0.0.1 (Run 0) Sampling data was successfully collected.

I appreciate any comment and help with getting started with Vtune.

Hi,

Could you please right-click on the activity and choose "Modify Activity"->select "Modify the select Activity"-> select "Configure" for "Application/Module Profile(s)? You should have "/opt/intel/vtune/samples/gsexample/datafile.txt" for "Command line arguments:" field.

If VTune Analyzer launches gsexample2a without arguments, it will stop sampling quickly. Can you use processes view, modules view, hotspots view to find ProcessBuffer function?

Regards, Peter
