Using libsdp with netperf shows some of the limitations of libsdp. netperf connects to the server on a well known socket, but then the server creates a second socket which it autobinds, checks to see which port was assigned, and passes the port number to the client which connects to the port. This second connection is then used for the data transfer. Since the connection is not on a well known port the way to match it is with the 'program' keyword: match program netperf > I'm now getting ~5300-5500 Mb/s (~660 MB/s) using SDP with netperf. > (256KB socket size....probably too small). The socket size socket option is still in the TODO file. -Libor _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
