Hi, 

Thanks, with this the problem is gone. In fact, no interface is posing problem if there is only one of them active. Anyway, using the options to mpiexec are just fine for the moment for me. 

Regards

Valentin

Strange - that shouldn't be happening. However, to get thru it, just restrict the interfaces OMPI uses. If it's the hardwired Ethernet that is causing the problem, then add

-mca oob_tcp_if_exclude en0 -mca btl_tcp_if_exclude en0

to your cmd line. If it's the wireless, then substitute en1 for en0 in the above.

Hi, 

It seems, the problem is happening if I have two active interfaces on my computer. Is there any configuration to use MPI_Comm_spawn_multiple on a machine with multiple interfaces ?

Hi, 

I'm using call to MPI_Comm_spawn_multiple in a quite big application. I've seen a deadlock occurred in a very strange situation. If I'm running my application on my Ubuntu 12.10 with OpenMPI 1.6.3 there is absolutely no problem. 

On my Mac OS X 10.8.2 with also OpenMPI 1.6.3, I'm experiencing a dead lock on an intrecommunicator resulting from the MPI_Comm_spawn_multiple only if my ethernet interface is enable. If I disable it, the deadlock is gone. 

Anyone has an idea of what is happening ? I joined the output of ompi_info on both OS X and Linux. 

Regards,

Valentin
