We encountered an ORTE bug with the error message, Error: unknown option “–hnp-topo-sig”, while using OpenMPI version 1.10.2 for arm64 on Ubuntu 14.04 server. More specifically, we ran the following command using 2 nodes with MPI: mpirun –hostfile /nfs/hostnames -n 4 /nfs/mpi-hello-world/mpi_hello_world

[tegra2-ubuntu:04159] Error: unknown option "--hnp-topo-sig" -------------------------------------------------------------------------- ORTE was unable to reliably start one or more daemons. This usually is caused by: * not finding the required libraries and/or binaries on one or more nodes. Please check your PATH and LD_LIBRARY_PATH settings, or configure OMPI with --enable-orterun-prefix-by-default * lack of authority to execute on one or more specified nodes. Please verify your allocation and authorities. * the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base). Please check with your sys admin to determine the correct location to use. * compilation of the orted with dynamic libraries when static are required (e.g., on Cray). Please check your configure cmd line and consider using one of the contrib/platform definitions for your system type. * an inability to create a connection back to mpirun due to a lack of common network interfaces and/or no route found between them. Please check network connectivity (including firewalls and network routing requirements). -------------------------------------------------------------------------- |
ORTE errors can happen because of a variety of different things, but it’s usually because your mpirun is not the same version as your mpi compiler. Even if you think that you only have one MPI version, you may in...
