I think you should not have troubles with your networks, at least with the number of machines you are considering. Perhaps you should increase a little the time between two communications ? With something like mpi_all_reduce for averaging the statistics over all the tree at each communication, more than 3 or 4 communications per second is useless. Averaging statistics in nodes with less than 5% of the total number of simulations might be useless also. Best regards, Olivier
