I’m using a binary distribution of OpenMPI 1.10.2. As linked, it requires
certain shared libraries outside of OpenMPI for orted itself to start. So,
passing in LD_LIBRARY_PATH with the “-x” flag to mpirun doesn’t do anything:
$ mpirun –hostfile ${HOSTFILE} -N 1 -n 2 -x LD_LIBRARY_PATH hostname
/path/to/orted: error while loading shared libraries: LIBRARY.so: cannot open
shared object file: No such file or directory
--------------------------------------------------------------------------
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).
--------------------------------------------------------------------------
How do I get around this cleanly? This works just fine when I set
LD_LIBRARY_PATH in my .bashrc, but I’d rather not pollute that if I can avoid
it.
