Is there a way to set up an interface analogous to Unix's loopback?  I suspect setting "-mca btl self,sm" wouldn't help since this is probably happening while the processes are bootstrapping.

The problem is that OMPI is looking for a tcp port for your computer. With no network enabled, you don't have one, and so mpirun aborts. I don't know of any way around this at the moment.

Have you tried to specify the hosts with something like this?

mpirun -np 2 -host localhost ./my_program

See 'man mpirun' for more details.

I hope it helps,

hi,

when my wireless adapter is down on my laptop, only localhost is configured.
In this case, when I mpirun 2 binaries on my laptop, mpirun fails with this error:


It looks like orte_init failed for some reason; your parallel process i
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

 orte_rml_base_select failed
 --> Returned value Error (-1) instead of ORTE_SUCCESS



when I turn on the wireless adapter back on, the mpirun works fine

Is there a way to make mpirun realize all my binaries run on the same box, and therefore don't need any other interface but localhost?

PS: this is ipconfig when the wireless adapter is off

ipconfig /all
