A cache for 256 nodes only generates 256 requests. Each request is a get table from a given sgid. The all to all connection model generates n^2 requests because each request is a get for a given sgid/dgid pair. Additionally, cached requests can be done when the application isn't running, with a fairly long or infinite update time. Arlin and I have discussed some caching options, including having multiple cache service daemons running on the subnet. If more than service is running, a nodes can select a particular service to communicate with. Communication can be done using RC to reduce the MAD overhead. - 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
