I'm generating otf file by compiling my programm with mpicc-vt.
It works very well and i can visualize the trace with the free Vampir.
But i need to analyze the results with some mathematical tools.
with vampir , i cannot extract any usefull data.

This value allow us to convert these tick values to seconds values.
THanks all.
