It's been a long time since I played with Cygwin, so take this with a grain of
salt. However, why don't you just use autotools in Cygwin and build OMPI ala
Linux, as outlined by Shiqing? I used to do that and run under ssh - IIRC, it
worked fine.
My memory may be faulty, though - still, might b
I am trying to build open-mpi 1.4.4 (latest stable from open-mpi.org)
using PGI compilers on a cray platform. PGI compilers' version is
11.9.0. I get the following error while building:

Hi Shiqing,
Thanks again for your quick reply (and George also for the previous reply),
I take it that the Windows 32 bit executable on the Open-MPI download site
is also built with cmake and suffers the same limitation? Was this intended?
Has anyone built a Windows 32 bit executable which
I'm afraid "--mca plm rsh" is not going to work. James is using a
Windows build, which doesn't have the rsh plm module.
There are only two plm modules for windows:
MCA plm: process (MCA ...
MCA plm: ccp (MCA ...
I think the binaries built by James contains only the process module,
which is i
Let's try to force the usage of ssh.
First try:
mpirun --mca plm rsh hostname
If not, go in the installation directory and rename lib/openmpi/mca_plm_rsh.*
to something without the .la and .so extension. Then re-run the hostname via
mpirun.

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
Hi Ralph,
Thanks for your quick response. I am using ssh without a passphrase, so
there was no need to start ssh-agent (ssh works as you can see from the
email I sent to George a little while ago . cc'd to users).
Anyway, I installed ssh-agent as you suggested in case ompi/orte accessed
it, b
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,
Hi George,
Thanks for your prompt reply, it is much appreciated. In response to your
questions:
Yes, I can execute ipconfig.exe through ssh without having to provide a
username or password (both in an ssh session and the command line).
I have run hostname as requested (the hostname is not
