[ofa-general] Problem running SDP apps using OFED 1.2

[Scott Weitzenkamp (sweitzen)]

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

should work)

Are you sure
