machines, that will dictate starting with the tcp oob component. Since we are able to reach every node both on IPv4 and IPv6, we do not have the bootstrapping problem. It looks to me that ORTE/OOB would be the easier part to start with anyway. -Christi

1 we initially use an IPv4 transport and in case 2 we initially use an IPv6 transport for the oob. If neither case 1 or 2 are possible, we abort. I hope that all can agree that this is a good starting point. Regards Christian -- Dipl.-Inf. Christian Kauhaus <
