Hi, I've installed Open MPI v1.10.2. Every VM on the cloud has two IPs (internal IP, public IP). When I run: mpirun --host <internal IP> hostname, the output is the hostname of the VM. But when I run: mpirun --host <public IP> hostname, the output is
bash: orted: command not found -------------------------------------------------------------------------- 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). Both IPs are the IP of the VM where MPI is running. Did I do something wrong in the configuration? Thanks for any help. Ping -----Ursprüngliche Nachricht----- Von: users [mailto:users-boun...@open-mpi.org] Im Auftrag von Jeff Squyres (jsquyres) Gesendet: Mittwoch, 1.
