Question

I want to optimize my code which is written in c++ on linux platform.For that i am using Intel VTune Performance Analyzer Profiler .When i am identifying Hotspots , it successfully runs the binary executable whose path i have specified and then it gives Error: "The Data Cannot be displayed,there is no viewpoint available for data ".

Can anyone help please in sorting this error.

I have just resolved the same problem, hope it's not too late for you.

Firs of all, you should enable debug information, i.e. compile with -g option:

icpc -g -o output source.cpp

or

gcc -g -o output source.cpp

if you prefer GNU compiler.

Another step (non-trivial) was found here: it says that at least for Ubuntu you have to type in:

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

This operation helped me and I hope it will help you and other people who face with this issue in future.
