Hi Envoyé , Thanks for the reply but I want to estimate the time of executing MPI_Bcast function by mathmatics. I found that we can achieve this by using LogGP model with this equation: T = ceil(log2p) . (L + 2 · o + (n − 1) · G but that does not give good accuracy for time evaluation.

These two programs are designed to evaluate Moi performance.
