Hi
I have installed Open MPI v 1.10.2 on two machines today using only the
prefix-option for configure, and then doing 'make all install'.
On both machines i changed .bashrc to set PATH and LD_LIBRARY_PATH
correctly.
(I checked by running 'mpirun --version' and verifying that the output does
indeed say 1.10.2)
Password-less ssh is enabled on both machines in both directions.
When i start mpirun form one machine (kraken) with a hostfile specifying
the other machine ("triops slots=8 max-slots=8),
it works:
-----
jody@kraken ~ $ mpirun -np 3 --hostfile triopshosts uptime
12:24:04 up 7 days, 43 min, 17 users, load average: 0.06, 0.68, 0.65
12:24:04 up 7 days, 43 min, 17 users, load average: 0.06, 0.68, 0.65
12:24:04 up 7 days, 43 min, 17 users, load average: 0.06, 0.68, 0.65

But when i start mpirun form triops with a hostfile specifying kraken
("kraken slots=8 max-slots=8"),
it fails:
-----
jody@triops ~ $ mpirun -np 3 --hostfile krakenhosts hostname
[aim-kraken:21973] 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).

The same error happens when i use '--host kraken'.
I verified that PATH and LD_LIBRARY_PATH are correctly set on both machines.
And on both machines /tmp is readable, writeable and executable for all.
The connection should be okay (i can do a ssh from kraken to triops and
vice versa).
Any idea what the problem is?
Thank You
Jody
