Hi I'm hoping that someone will be able to help me figure out a problem with connecting to multiple nodes with v1.8.4.
Currently, I'm running into this issue: $ mpirun --host host1 hostname host1 $ mpirun --host host2,host3 hostname host2 host3 Running this command on 1 or 2 nodes generates the expected result. However: $ mpirun --host host1,host2,host3 hostname Permission denied, please try again. Permission denied, please try again. Permission denied (publickey,password,keyboard-interactive). -------------------------------------------------------------------------- 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). -------------------------------------------------------------------------- This is set up with passwordless logins with passphrases/ssh-agent. When I run passphraseless, I get the expected result. What am I doing wrong? What can I look at to see where my problem could be?
