And you need the ConnectX-only masked atomics? Or do the standard IB atomic operations work for you? Of course using atomics at all means that things don't work on iWARP. > Send with invalidate is an exact match for our current RDS V3 rdma > driver - and should be more efficient than the current background > syncing of the tpt to ensure keys are invalidated. How does send with invalidate interact with the current IB FMR stuff? Seems that you would run into trouble keeping the state of the FMR straight if the remote side is invalidating them. Also I would think that send-with-invalidate would be much more expensive than the current FMR method of batching up the invalidates, since you don't get to amortize the cost of syncing up all the internal HCA state. - R. _______________________________________________ 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
