I restarted openibd and now my interfaces are up.

mach#1
ib0       Link encap:InfiniBand  HWaddr
80:00:00:02:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00
          inet addr:140.221.37.46  Bcast:140.221.37.255  Mask:255.255.255.0
          inet6 addr: fe80::211:7500:ff:d7f2/64 Scope:Link

mach#2
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  Mask:255.255.255.0
          inet6 addr: fe80::211:7500:ff:d802/64 Scope:Link

I am able to "ping 140.221.37.46" from machine#2.

mach#2 > ping 140.221.37.46
PING 140.221.37.46 (140.221.37.46) 56(84) bytes of data.
64 bytes from 140.221.37.46: icmp_seq=1 ttl=64 time=2.49 ms
64 bytes from 140.221.37.46: icmp_seq=2 ttl=64 time=0.106 ms
64 bytes from 140.221.37.46: icmp_seq=3 ttl=64 time=0.098 ms
--- 140.221.37.46 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2002ms
rtt min/avg/max/mdev = 0.098/0.900/2.498/1.130 ms

But sockets over SDP still gives me the same "Network Unreachable error".
