o.k,, so the generated file will have the following line for all of the IPoIB I/Fs: OpenIB-cmaX u1.2 nonthreadsafe default libdapl.so of_udapl.1.2 "192.168.0.47 1" "" (X run from 0 to n) and a default OpenIB-cma which will be the first IPoIB I/F that was found. i have 2 more questions: 1) what is the number after the IP? (ib port? starts from which value?) 2) do you need any lines with the scm ? (if the answer is yes, can you please send me an example line?) thanks Dotan _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
