There is a problem with MPI - program works when there is an internet connection on my PC, but doesn't work without it.

I got this error:

It looks like orte_init failed for some reason; your parallel process is 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

What is the cause of this problem?

    Looks like you probably need to turn off some of the BTLs. It's been a while since I used Open MPI, but as I recall, you might try turning of tcp and leaving on self and sm. – Wesley Bland Dec 01 '14 at 15:25

    Try running with `mpiexec --mca btl ^tcp --mca oob ^tcp ...` though it would have helped if you'd have given more details like OS, list of interfaces, etc. – Hristo Iliev Dec 01 '14 at 22:18

    Do you mean no internet connectivity or you just disable your network interface? – Valentin Clement Jul 25 '16 at 13:50
