Hi Shiqing,
I agree. I think that I am somehow using WMI, but this is happening
both with the Open-MPI windows binary (OpenMPI_v1.5.4-1_win32.exe)
and also with versions of the binaries I built (1.4.3 & 1.5.1 from svn).
What do I have to do to get OpenMPI to use ssh instead of WMI. From
what I can see of the configuration with ompi_info, the following
seems correct:
$ ompi_info -all
Package: Open MPI hpcfan@VISCLUSTER26 Distribution
Open MPI: 1.5.4
Open MPI SVN revision: r25060
Open MPI release date: Aug 18, 2011
Open RTE: 1.5.4
Open RTE SVN revision: r25060
Open RTE release date: Aug 18, 2011
OPAL: 1.5.4
OPAL SVN revision: r25060
OPAL release date: Aug 18, 2011
Ident string: 1.5.4
….
MCA orte: parameter "orte_rsh_agent" (current value: <ssh : rsh>, ….
….
MCA plm: parameter "plm_rsh_agent" (current value: <ssh : rsh>, ….
….
Is there a cmake configuration option I need to set for a Windows
build to use ssh? Is there some environment or package configuration
option I need to set?
Thanks again for your help, I am keen to know what I am missing.
Best regards,
Jim

Hi James,
One other possibility could be that ssh is actually not used at all.
Did you build Open MPI under Cygwin? Is the ssh module shown up in
the ompi_info output?
The user credential message looks very familiar to me as it seems
from the WMI (Windows Management Instrumentation) module, where the
'save credential' option has not been implemented.

Afraid I'm no OpenSSH expert, but it sounds like there is an issue
with its configuration. Check out the OpenSSH config options to see
if something fits.
I did a quick search and found this, as an example:

Note the need to run ssh-agent to cache login credentials.

Hi all,
I am trying to setup Open-MPI across two Windows 7 machines with UAC
disabled ……
Cygwin with OpenSSH is installed, and I can successfully ssh to each
machine without entry of username and password:
JimT@JimT-PC ~
$ ssh NanoOneQuad
Last login: Tue Feb 7 01:42:02 2012 from jimt-pc
JimT@NanoOneQuad ~
$
Regardless of this, mpirun insists on asking for a username and
password; then asks to save credentials, but if selected, responds
with not implemented. If saving credentials is not selected, then I
can see that the task starts on the other machine (in task manager)
and that the task runs to completion OK:
JimT@JimT-PC ~
$ mpirun -H NanoOneQuad ipconfig.exe
connecting to NanoOneQuad
username:JimT
password:**************
Save Credential?(Y/N) y
[JimT-PC:03784] This feature hasn't been implemented yet.
JimT@JimT-PC ~
$ mpirun -H NanoOneQuad ipconfig.exe
connecting to NanoOneQuad
username:JimT
password:**************
Save Credential?(Y/N) n
JimT@JimT-PC ~
$
Please let me know what I have missed. I have gone through the FAQs
and have rebuilt the windows version but can’t seem to get past this.
Thanks and best regards,
Jim
