I'm now using Intel VTune Amplifier XE 2015. Also, I have no problem in running Tachyon (sample code).
I was trying to analyze an executable file generated after complilation of a C source code with OpenMP API.
When I run Advanced Hotspots Analysis, I can't view the result of analysis at OpenMP region. It stated "No Data To Show".
Below are the steps that I'd taken to run the analysis:
1) source /opt/intel/vtune_amplifier_xe_2015/amplxe-vars.sh
2) gcc -fopenmp -g Matrix.c -O2 -o Matrix.exe
3) export EDITOR=gedit
