[mpich-discuss] Windows & Name publishing

[Jayesh Krishna]

Hi,
 Yes, we should fix this. The issue arises because SMPD managers don't
contact each other (like in mpd to form a ring) before the job is started.
 
(PS: This problem could be *fixed* in unix systems by having the SMPD
managers publish names to managers on the hosts listed in the smpd
configuration file.) 
 
Regards,
Jayesh

That's a very serious bug in smpd - this is exactly what
Lookup_name/Publish_name are for.

Hi,
MPI_Publish_name() from one MPI job and an MPI_Lookup_name() from another
MPI job does not work on windows (Does not work with the SMPD process
manager).

(PS: In windows, the Mandelbrot visualizer, mpich2/examples, connects to the
solver using windows sockets.)

Hi,

I'm writing a client/server application similar to the pman_vis sample. 
I would use the name publishing service
to manage the port name. My problem is that the server registers the pair
<port name, service name> without errors but on the client side the
MPI_Lookup_name fails reporting an error code
0C01FF21 hex.

Does somebody knows what is the cause?

I'm using:
Windows XP pro
Visual Studio 2005
MPICH2 v 1.0.6p1 (I compiled the source code)

I start my server using the command
mpiexec -channel mt -n 5 CmdServer.exe

The application work well if I copy the port name manually.

Thanks
Andrea
