Details
I have two fully updated arch systems host1 and host2, both with openmpi 4.1.5-5 installed. Running:
$ mpirun -v -n 2 --hostfile hosts.txt bash -c 'echo $HOSTNAME'
in host1, where hosts.txt is:
host1 slots=1 host2 slots=1
fails with:
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).
Downgrading the remote host to openmpi 4.1.5-4 solves the problem:
$ mpirun -v -n 2 --hostfile hosts.txt bash -c 'echo $HOSTNAME' host2 host1
The local version of openmpi does not seem to influence the result.
The same thing happens with -n 1, even though the program is launched locally.
