Hi,
I am trying to implement the following collectives in MPI
sharedmemory, Alltoall, Broadcast, Reduce with zero copy

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.
So i try to use otfdump to extract the
