Hi Clinton,
I suggest that you build Open MPI directly on the Windows Server, so
that the system dependencies wouldn't get wrong. If you just copy around
the binaries, there will be problems:
your local PC (I guess it's Windows Vista or 7) has inet_pton, but the
Windows Server 2003 doesn't have it in the system level. So the binaries
won't work. I'll fix this problem very soon.
Regards,
Shiqing

Hi Shiqing,
Thanks very much for your last email -- it was good help. I think my
questions about security and group permissions on Windows are answered
with the MSDN links for configuring remote access.
Anyway, I have managed to compile using VS C++ 2008 on my local PC
(32bit) and it worked.
Then I moved to our Windows Server 2003 x64.
I compiled the x64 test code and and I run it, I got
"The procedure entry point inet_pton could not be located in the
dynamic link library WS2_32.lib"
1.I found a thread on this message but there was no solution at that
time. Has this problem been solved? If yes, How do I fix this?
2.Also I read somewhere in the web that OpenMPI on Windows x64 for
Fortran does not work properly yet. Is this still true?
Thanks for your help.

*Subject:* Re: [OMPI users] How to setup and use nodes for OpenMPI on
Windows
Hi Clinton,
Just wondering if anyone can point me to the detailed information on
how to setup multiple nodes and network them together to use OpenMPI.
Also what is the proper way to specify which nodes to run on. I wish
to use OpenMPI on the Windows XP or Windows Server 2008 platform, with
Intel Fortran 11 as the programming language.
If you use Windows XP, you have to specify --host or --hostfile option
in the command line. see mpirun --help for more details. On Windows
server 2008, you can also specify the node names through the Job
Monitor GUI.
I have searched Google and also looked through the OpenMPI website but
there does not seem to be any comprehensive documents to run OpenMPI
on Windows, especially setting up the nodes.
For working on multiple nodes on Windows XP, the only thing you have
to make sure is that the WMI is able to launch process remotely, which
referred to the two MSDN links in the WINDOWS.TXT file. Other then
this, no other special setting is necessary, just install one
pre-compiled installer, it will configure the environment
automatically for you.
Many years ago, I played a bit with Mpich and LAM MPI on a purely
Linux platform. On Linux clusters, it is easy -- the head node see
each of the compute nodes. As I remember, the programmer need to only
write the names of the compute nodes in some sort of config file. The
job is submitted and based on the compute nodes listed, the mpi will
run on them.
On Windows, what kind of networking is needed to tie the nodes
together? (assuming we are not using any of the MS HPC Pack or Compute
Cluster). How do we specify which nodes to use? How do we specify any
security or group permissions for the nodes?
You should have at least TCP connections among the nodes. I don't
understand what security and group permissions stands for here.
Regards,
Shiqing
