Libor,
How did you generate the above numbers?  netpipe?

I'd like to add the "HP ZX1" (and maybe parisc) column.


BTW, I've got several systems loaded with:
gsyprf3:~# lsmod
Module                  Size  Used by
ib_sdp                225032  0 
ib_cm                  86032  1 ib_sdp
ib_sa                  23980  1 ib_sdp
ib_mthca              211335  0 
ib_mad                 82808  3 ib_cm,ib_sa,ib_mthca
ib_core                85288  5 ib_sdp,ib_cm,ib_sa,ib_mthca,ib_mad
...

and zero clue how to get it to talk to another system.
ie "ifconfig -a" isn't listing any new interfaces. :^(

The most recent "How-To test SDP" for gen1 posted on Jun 17, 2004:
	http://openib.org/pipermail/openib-general/2004-June/002892.html

It references libsdp.so which doesn't seem to exist in gen2.
Has anyone written an update for gen2?

thanks,
grant
