Can you ping between the two nodes using the IPoIB IP address?

Hi Dotan,
ifconfig shows up
ib0 Link encap:InfiniBand HWaddr
80:00:00:03:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00
inet addr: 140.221.37.32 Bcast: 140.221.37.255
<http://140.221.37.255> Mask:255.255.255.0
inet6 addr: fe80::211:7500:ff:d802/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:65520 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:1 errors:0 dropped:5 overruns:0 carrier:0
collisions:0 txqueuelen:128
RX bytes:0 (0.0 b) TX bytes:68 (68.0 b)
does this mean that the apps would now use IPoIB ? How do i tell
when IPoIB is working and when it isnt ? Because I assume when it isnt
it would default to Ethernet ?
It will be great if I can get this cleared.
Thanks
Zulfi

Does a simple "ping" between the nodes is working?
(this way you can be sure that IPoIB is working and SDP
should work)
