Depends on what you are looking to do with your cluster. Is it production ? What ULPs are you looking to use ? > I've got a 256-node cluster with hierarchical switches that has never really > worked well with the vendor stacks, If you can live with just IPoIB then OpenIB might be good enough right now. > and the opensm has never run more than one day without segv; > is openib solid enough that I can run with it?

This port is pretty new and has only been used in small clusters to date. > Are there tools for tracing the fabric and looking for problems? There are a number of diagnostic tools currently available: ibstat/ibstatus, ibnetdiscover (which walks the fabric), smpdump, sminfo, and mad_test currently. These are all pretty new. There was a writeup on these posted some time ago. If IPoIB is sufficient, then a 2 phase approach to migration might be possible: 1. Use OpenIB on end nodes but use some vendor's SM 2. Bring up a single or a couple of OpenIB end node(s) and use OpenIB OpenSM shutting off the other SMs If that works, then you can convert over. -- 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
