Subject: MPI_Bcast from OpenMPI

Hi, 
One more question:
I have executed the MPI_Bcast() in 64 processes in 16 nodes Ethernet multiple links cluster.
The result is shown in the file attached on this E-mail.
What is going on at 131072 double message size?
I have executed it many times but the result is still the same.

THANK YOU!
