vtun_amplifier_xe_2017： Warning: Cannot locate debugging symbols for file `xxx'

[seven_w_]

hi

    I install vtun_amplifier_xe_2017 in CentOS Linux release 7.2.1511 (Core) by root，and it installed in /opt/intel, and i run the samples with amplex_gui in below：

[root@localhost ~]# cd /opt/intel/vtune_amplifier_xe_2017.0.2.478468/samples/en/C++

[root@localhost C++]# tar -xvzf tachyon_vtune_amp_xe.tgz

[root@localhost C++]# cd tachyon/

[root@localhost tachyon]# make

[root@localhost tachyon]# ls
android  common  dat  Makefile  res  src  tachyon_analyze_locks  tachyon_find_hotspots  tbbforexamples

[root@localhost tachyon]# cd /opt/intel/vtune_amplifier_xe_2017.0.2.478468/bin64/

[root@localhost bin64]# ls
amplxe-androidreg.sh  amplxe-gui        amplxe-python       amplxe-runss.py   aps.sh       gui-freeze-handler  mem_bench  prepare-debugfs.sh  sep.events    stackcollector
amplxe-cl             amplxe-perf       amplxe-python-exec  amplxe-sniper.py  crashreport  k1om                pin        reserve_pmu         sps-start.sh
amplxe-feedback       amplxe-perf-sync  amplxe-runss        aps.py            emon         map.events          pinbin     sep                 sps-stop.sh

[root@localhost bin64]# ./amplxe-gui

first, I add new Project, Project name: tachyon,  Location: /root/intel/amplxe/projects,

then, From the left pane, select the local target system from the Accessible Targets group, From the right pane select the Launch Application target type

then, Specify and configure the target: For the Application field, browse to /opt/intel/vtune_amplifier_xe_2017.0.2.478468/samples/en/C++/tachyon/tachyon_find_hotspots, For the Application parameters field, enter /opt/intel/vtune_amplifier_xe_2017.0.2.478468/samples/en/C++/tachyon/dat/balls.dat

then, click the Choose Analysis button on the right to switch to the Analysis Type tab

then, From the analysis tree on the left, select Algorithm Analysis > Basic Hotspots

Finally,Click the Start button on the right command bar to run the analysis

the result in Collection Log:

Result finalization has completed with warnings that may affect the representation of the analysis data. please see details below.

how can i do the warning?

Hello Seven,

As you see the warnings are about absence of detailed debug info for systems or internal VTune libraries (that have it usually stripped) that you hardly will optimize. So you can disregard them.

The important thing is not to have warnings for your modules of interest like tachyon_find_hotspots that you are going to optimize so you will need both function and source line information from debug info for them.

Thanks & Regards, Dmitry
