[ofa-general] Tools for Infiniband Performance measurement

[Dukle, Kapil (GE Healthcare)]

Hi all,
 
I was wondering if there are any tools specific for
Infiniband-performance measurement - throughput, round trip time with
adjustable
packet sizes.

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
