You can use the tcp_if_include/tcp_if_exclude with address ranges instead of
names. ompi_info --mca btl tcp give you some hints:

We just discovered this ticket, which might describe the same problem that
we have:
https://svn.open-mpi.org/trac/ompi/ticket/1505
It seems unresolved... do you have a workaround for it? I've seen the "-mca
opal_net_private_ipv4 " parameter, but I don't exactly know how to use it...

Can you define "common"? Do you mean that eth0 on one machine is on a
different network then eth0 on the other mac
No, unfortunately specification of interfaces is a little more
complicated... eth0/1/2 is not common for both machines.
I've tried to play with (oob/btl)_tcp_ if_include, but actually... I don't
know exactly how.
Anyway, do you have any ideas how to further debug the communication
problem?

There are two connections to be specified:
-mca oob_tcp_if_include xxx
-mca btl_tcp_if_include xxx

Hi,
I'm working with Grzegorz on the mentioned problem.
If I'm correct on checking the firewall settings, "iptables --list" shows an
empty list of rules.
The second host does not have iptables installed at all.
So what can be a next reason of this problem?
By the way, how can I enforce mpirun to
I'd check the firewall settings. The stack trace indicates that the one host
is trying to connect to the other (Open MPI initiates non-blocking TCP
connections that can be polled on later).

Have you double checked your firewall settings, TCP/IP settings, and SSH
keys are all setup correctly for all machines including the host?

Hi all,
I've got a problem with sending messages from one of my machines. It
appears during MPI_Send/MPI_Recv and MPI_Bcast. The simplest case I've
found is two processes, rank 0 sending a simple message and rank 1
receiving this message. I execute these processes using mpirun with
-np 2.
