Note that NetPIPE 3.7 will only use the first port of the first HCA
in your machine (which is a fairly common configuration).
I have submitted a patch to the NetPIPE maintainers that allows you
to specify on the command which port / HCA to use for testing.

Hi all,
I was wondering if there are any tools specific for Infiniband-
performance measurement - throughput, round trip time with adjustable
packet sizes.
The latest NetPIPE benchmarking utility has Infiniband support:
It will measure what you asked.

*Subject:* ibping fails in loopback mode
Hi all,
I'm having trouble getting ibping to work in loopback node. The
original config is to connect first port of Blade 1 with first
port of Blade 2.
For my loopback test, I have connected the Infiniband cable
between the 2 ports on the same Linux blade.
Both opensm and ibping (server mode) seem to be running on the
blade. Ping succeeds to the first active port, but fails
for the second one. See below...
Why is the ibping to the second active (and linkup) port
failing? Am I missing something? The version is OFED1.0
