NodeDescription itself is always 64 bytes. Whether it is null terminated at 0 bytes and the implications of this is another story. This approach could result in nodes not having a 0 byte null terminated NodeDescription. Since this is being used as a convenient administrator (human) node identification string to say it is that node over there, it loses that meaning when it is not filled in. That was the problem I was referring to. It's the human side of using the tools. -- Hal _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
