To clarify the motivation more, a question to answer is if we ignore iWarp completely, does it make sense to provide a higher level communication manager for IB. I believe that it does, especially for userspace applications. This lets us leverage existing name services, ipoib, and provides an interface that is simpler for most users.
A lot of existing applications and test programs exchange IB QP information over TCP connections, including programs that communicate using UD QPs. If you compare the amount of work necessary to establish communication over an RC QP versus a UD QP, the difference is basically a single MAD, which isn't even needed. So there's a fair amount of work that can be shared by a higher level CM. - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
