Hi,

I am new to MPI so forgive me if the following is obvious.

I have variable sized data which I would like to send between two peers.
I wouldn't like to malloc, every time, a buffer with the appropriate
size, fill
in the data and to pass to the MPI_send() for delivery.

I thought of creating a communication pipe (ala unix) between 2 peers so
that the 
data is pushed immediately to the pipe, avoiding to buffer/pack it a
priori. 
In parallel, the receiver will start to collect that data and process
it.

Is it possible to implement such pipes in MPI/FM ? How ? 
Are there other efficient solutions ? 

Thanks for any help.
