This script generates a deployment file for the all2all program. It takes
a SimGrid platform file as first argument and the number of wanted peers as
second argument. If the amount of peers exceeds the amount of available
-hosts in the deployment file, several peers will be placed on the same host.

+The third argument is a size of the message to send ( octets )

+If a fourth argument is passed, this is the source of the broadcast
+(given as a number between 0 and nb_host-1).
