Hi Shiqing,
I must have missed your response among all the e-mails that get sent to
the mailing list. Here are a little more details about the issues that I
am having. My client/server programs seem to run sometimes, but then
after a successful run I always seem to get the error that I included in
my first post. The way that I run the programs is by running the server
application first, which generates the port string, etc. I then proceed
to run the client application with a new call to mpirun. After getting
the errors that I e-mailed about I also tried to run ompi-clean, but the
results are the following:
>ompi-clean
[Lazar:05984] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file
..\..\orte\r
untime\orte_init.c at line 125
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):
orte_ess_base_select failed
--> Returned value Not found (-13) instead of ORTE_SUCCESS
--------------------------------------------------------------------------
Any help with this issue will be greatly appreciated.
Thank you,
Kalin

Hi Kalin,
Sorry for the late reply.
I checked the code and got confused. (I'm not and MPI expert) I'm just
wondering how to start the server and client in the same mpirun command
while the client needs a hand-input port name, which is given by the
server at runtime.
I found a similar program on the Internet (see attached), that works
well on my Windows. In this program, the generated port name will be
send among the processes by MPI_Send.
Regards,
Shiqing

Hi there,
I am trying to create a client/server application with OpenMPI, which
has been installed on a Windows machine, by following the instruction
(with CMake) in the README.WINDOWS file in the OpenMPI distribution
(version 1.4.2). I have ran other test application that compile file
under the Visual Studio 2008 Command Prompt. However I get the
following errors on the server side when accepting a new client that
is trying to connect:
[Lazar:02716] [[47880,1],0] ORTE_ERROR_LOG: Not found in file

[Lazar:2716] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)
--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 476 on
node Lazar exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------
The server and client code is attached. I have straggled with this
problem for quite a while, so please let me know what the issue might
be. I have looked at the archives and the FAQ, and the only thing
similar that I have found had to do with different version of OpenMPI
installed, but I only have one version, and I believe it is the one
being used.
Thank you,
Kalin
