Usually this is due to multiple calls to the marker API
in your measured code.

Without an code example it is difficult for me to help.

It is important that you install likwid-pin to work correctly with make install.
You execute the program serial above. If it is a threaded program you have to 
measure the same number of threads you intrumented.

Find attached two examples for usage. One is serial (dofp.c) and one OpenMP 
parallel (openMP.c). If it works please let me know what part in the 
documentation maybe was not clear enough.

As I got no further answer I regard this issue as solved.
You might reopen it if there is still a problem.
