Module of interest field for callgraph collector

Hello,

I have installed vtune from vtune_linux_8.0.245.tar.gz

I can not create an activity :

[tunali@linux ~/profiling]$ cat program.c
int main(void){}
[tunali@linux ~/profiling]$ gcc program.c
[tunali@linux ~/profiling]$ ls -l a.out
-rwxr-xr-x 1 tunali pwoc 6597 May 15 19:14 a.out*
[tunali@linux ~/profiling]$ pwd
/home/tunali/profiling
[tunali@linux ~/profiling]$ /opt/intel/vtune/bin/vtl activity -c callgraph -app /home/tunali/profiling/a.out -moi /home/tunali/profiling/a.out

Somewhere in the documentation it is written that for the callgraph collector type application and "module of interest" should be the same. Just to experiment I tried the following :

[tunali@linux ~/profiling]$ /opt/intel/vtune/bin/vtl activity -c callgraph -app /home/tunali/profiling/a.out -moi gui
VTune Performance Analyzer 8.0 for Linux*. FOR NON-COMMERCIAL USE ONLY

[tunali@linux ~/profiling]$

However I don't have a module called gui.

When I try to run the activity (the one created with -moi gui) I get the following :

[tunali@linux ~/profiling]$ /opt/intel/vtune/bin/vtl show
VTune Performance Analyzer 8.0 for Linux*. FOR NON-COMMERCIAL USE ONLY

VTune Performance Analyzer 8.0 for Linux*. FOR NON-COMMERCIAL USE ONLY

The Activity is running.

Here are the definitions of my system :

I have rebuilt the sampling driver for my kernel but I think it just hangs the machine because it is built on Opterons :

[tunali@linux ~/profiling]$

But I suppose this should not affect callgraph collector.

When I tried to start vtlec I got the following message many times :

[tunali@linux ~/profiling]$ /opt/intel/vtune/bin/vtlec
RENDER extension not supported by server

The launcher script has detected that the display does no support anti-aliased fonts.
This may cause significant perfromance degradation.
Please ensure that anti-aliasing is turned off in /etc/fonts.conf or ~/.fonts.conf files.

Turn off this warning in future (Yes/No) ? [No]
Press ENTER key to accept default choice, or input a valid choice :

Cannot load module

even though /usr/lib/64/pango/1.2.0/modules/pango-basic-xft.so is clearly there :

[tunali@linux ~/profiling]$ ls -l /usr/lib64/pango/1.2.0/modules/pango-basic-xft.so
-rwxr-xr-x 1 root root 8960 Sep 8 2003 /usr/lib64/pango/1.2.0/modules/pango-basic-xft.so*
[tunali@linux ~/profiling]$

vtlec does not display and does not respond to anything.

Overall it was quite an experience...

Thanks.

Omer, this is an excellent, data-rich posting. A few thoughts:

1) examine the release notes for the software you are working with. You must install it on supported, listed OS versions and CPUs, clearly outlined in the supported list there. By not doing this, you create a laboratory out of the installation, and anything is possible. Anything.

2) For more clues about your unsupported environment, run the VTune Quality Feedback Agent, which it sounds like you don't know about, yet. Default location:

/opt/intel/vtune/bin/vtqfagent

By running that, you will create an ASCII text log file (easy to vi) that shows you every detail about your server and VTune installation, including the installation log itself (installation log shows all installation successes, failures, all user decisions, default choices, etc.) You could learn a lot by runningvtqfagent and reading the log.

3) If you chose to experiment by installing on a SUPPORTED OS/CPU combination, and you see the same problem with your extremely simple sample program, Intel Premier Support would *love* to hear about it. Those guys eat this stuff up for breakfast!

cheers
