Hi,

   I have a small question regarding creating separate group for
communication among the processes. If I create a new group and
communicator to exchange data among, let say 4, processes out of
total, let say 20, processes, instead of using all 20 processes for
that data exchange, will there be any improvement in overall speed up
or efficiency?? Does have this to deal with reduction of communication
overhead?

   Thank you.
