I guess I missed something somewhere. The customers still buy the hardware cause it runs an application, they don't just go out and buy some cool InfinBand hardware and then go see what they can use it for. >>Adding undocumented requirements to a standard isn't the way to entice >>more people into implementing or using it. Well, sometimes the applications drive the feature set, even though it is not part of the actual standard. Unfortunate, but a fact of live. >I would challenge you to find a single ISV that would prefer a >situation where some "infiniband" middleware requires things which >aren't in the standard. If the feature gives them a huge advantage in performance (and it does) and all of the hardware vendors that they deal with already implement it, then yes, they will force, by defacto standard that all other newcomers implement it or face the fact that no one will buy their hardware. It seems like that is what is happening in this case. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
