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:

James,
There is no mention about username or password in OMPI. I guess one of the
applications used in the process, either the ssh or the ipconfig.exe is missing
the current context to be executed without a higher level of credentials.
Can you execute ipconfig.exe once connected through ssh wit

You should be able to build Open MPI on Windows either un
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:

$ ssh NanoOneQuad

Tom/All,
In case it is not already obvious, the GPFS Linux kernel module
takes care of the interaction between the Linux IO stack, POSIX
and the GPFS under layer. MPI-IO interacts with the thusly modified
kernel through the POSIX API.

Thanks, these are the kind of suggestions I was looking for. I will try
them. But I will have to twist some arms to get the 1.5 upgrade. I
might just install a private copy for my tests.

P.S. I have tested with OpenMPI 1.4.5rc4 and the problem is still there.

This is a known problem and is unlikely to be fixed. The solution is simply to
use the medium size f90 module, which means you won't have strict type checking
on all MPI functions that take 2 choice buffers (e.g., MPI_SCATTERV).
In the OMPI v1.7 series, we have a wholly revamped set of Fortran
