Subject: Re: [OMPI users] Number of Sockets used by OpenMPI
From: Charles Salvia (chsalvia_at_[hidden])

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)?

Thanks.
