Hi Prasadcse,
At each iteration, each process chooses one other process to send to
(based on the line it has just read from a file). If we send the
number of packets to expect in advance, we then need to send an
`expect zero packets from me' message to all the processes that we
don't have a m

I think its a real good way to use MPI_Irecv/MPI_Test on the receiver side
to avoid any blocks which sender might run in to. But I'm a bit curious on
the fact, Can't we use a special message beforehand between the
sender/receivers to let the receivers know how many messages to expect ?
This way the
