Department, we are trying to profile mpich source code itself. So as to <br>
analyze the internal function calls made by the mpich functions like <br>
MPI_Bcast etc. I have tried so many profilers like IPM, gprof to <br>
compile the MPICH source code. But It turned out nothing works. I have <br>
also so many flags but nothing worked out. Could you please tell me how <br>
to profile the mpich source code itself.<br>
