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.

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
