Unfortunately, without the preconnect flag set the output is inaccurate. As the connections between peers are made in a lazy way, in the best case you will see the BTL that is supposed to be used, and not the one that will be used. In order to give an accurate view of the connections, you will

Jeff, the below sounds good if we really believe there is going to be a whole bunch of addons. I am not sure NBC really constitute as an addon than more some research work that might become an official API. So I look at the NBC stuff more like a BTL or PM that is in progress of being develope

I just -know- this is everyone's favorite subject, but... Brian used to take care of the ROMIO code in Open MPI, but he has now moved on to greener, happier pastures. As he left, he did raise the question of who was going to maintain ROMIO, which we all happily dodged. I raise this question again

I think your proposed approach is an excellent one! I know it will take work to implement, which raises its own issues, but I do believe that it is the only real long-term solution. Just my $0.002. I would be willing to help with implementation, if that would be of use. Not sure I understand the b

All these comments are good. I confess that although I should have, I really did not previously consider the complexity of adding in N contrib packages to OMPI. The goal of the contrib packages is to easily allow additional functionality that is nicely integrated with Open MPI. An obvious

I believe Brian and Terry raise good points. May I offer a possible alternative? What if we only include in Open MPI an include file that contains the "hooks" to libNBC, and have the build system only "see" those if someone specifies --with-NBC (or whatever option name you like). If you like, you c
