Yes, that's pretty easy. > I could checkin the source for the modified ttcp's but I'm not sure > exactly where... (gen2/users/libor ???) I wouldn't bother for the "#define AF_INET AF_INET_SDP" above. If the AIO version is more complicated, maybe create an "examples" directory under gen2/src/userspace?

Ah! *click* ib_ipoib is missing! For whatever reason I didn't realize ib_sdp only adds the alternative net family. Yes, I did notice the "NET: Registered protocol family 27" when loading ib_sdp. I had associated ip_ipoib with providing TCP/IP but of course it does NOT. ipoib *uses* the existing stack for AF_INET. Doh!

Or perhaps links to the right projects (e.g netperf.org) in a userspace/examples/README file? Or maybe more obvious here -> http://www.openib.org/doc.html ? I just stumbled across links to http://www.web-polygraph.org/ again. That's not something I use every day... Pointers to different tests that are relevant to evaluating IB are helpful. If someone starts it, I'll contribute to the list. thanks, grant _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
