Not clear if the following failure is Solaris-specific, but it *IS* a regression relative to 1.8.3.
The system has 2 IPV4 interfaces: Ethernet on 172.16.0.119/16 IPoIB on 172.18.0.119/16 $ ifconfig bge0 bge0: flags=1004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4> mtu 1500 index 2 inet 172.16.0.119 netmask ffff0000 broadcast 172.16.255.255 $ ifconfig pFFFF.ibp0 pFFFF.ibp0: flags=1001000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,FIXEDMTU> mtu 2044 index 3 inet 172.18.0.119 netmask ffff0000 broadcast 172.18.255.255 However, I get a message from mca/oob/tcp about not being able to communicate between these two interfaces ON THE SAME NODE: $ /shared/OMPI/openmpi-1.8.4rc1-solaris11-x86-ib-ss12u3/INST/bin/mpirun -mca btl sm,self,openib -np 1 -host pcp-j-19 examples/ring_c [pcp-j-19:00899] mca_oob_tcp_accept: accept() failed: Error 0 (0). ------------------------------------------------------------ A process or daemon was unable to complete a TCP connection to another process: Local host: pcp-j-19 Remote host: 172.18.0.119 This is usually caused by a firewall on the remote host.
