I don't know too much about opensm yet, but I can try looking into it, or try talking someone into this :) But I'm happy we all agree it's a good idea. Let's add this to osm/doc/todo? > I was > saying that a static rate default of 1x SDR would eliminate the join > errors (at the debug "expense" of what I think are harder to find > performance issues). Sorry I didn't make that clear before. I think if we either 1. Add an option to disable 1x support at endnode or 2. Implement a tool to find and report 1x links or 3. By default, report 1x links in opensm log as errors Then this issue will be easy to debug. -- MST _______________________________________________ general mailing list [EMAIL PROTECTED] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
