I am using OMPI 1.3.3.
I didn't realize that earlier versions may behave differently. Is
there perhaps an advantage/disadvantage to using 1 socket to connect
to each process, versus 2 sockets (one for sending and one for
receiving)?
Not really. There's still only 1 network wire. The kernel already
has separate sending and receiving buffers for a single socket.
Adding another socket would just consume more kernel resources.
