Subject: [OMPI devel] trac #2034 : single rail openib btl shows better bandwidth than dual rail (12k< x < 128k)
From: Don Kerr (Don.Kerr_at_[hidden])

I intend to make the change suggested in this ticket to the trunk. The
change does not impact single rail, tested with openib btl, case and
does improve dual rail case. Since it does involve performance and I am
adding a OB1 mca parameter just wanted to check if anyone was interested
or had an issue with it before I committed the change.
