/home/hx019035/bin contains the local installation of OMPI 1.3.3
The LD_LIBRARY_PATH variable contains /home/hx019035/lib:
These variables are being set in the .profile file on the hpcc00 node.
Would there be a change anywhere else?

Yes, it does. But the error message indicates a 1.2 version is running on
hpcc00.

Just a quick question. Would mpirun -version give me the version of the
mpirun being executed? I am getting the result of that as 1.3.3.

Hate to tell you this, but your output clearly indicates you are NOT running
1.3.3 - that is an output from a 1.2.x version of OMPI.
Check you path and ld_library_path - you're still picking up the 1.2.5
version somewhere.

Hi,
Please refer to the emails below.
I have made an upgrade to Open MPI 1.3.3 as suggested. The necessary
environment variables have all been set. Attaching the output of ompi_info
-all. However, the errors continue to persist.

You can always install your own version of Open MPI under your $HOME
or somesuch -- there is no requirement that Open MPI is installed by
root in a central location.
That being said, you might want to check with your administrator to
ensure that this is ok with local policies -- see if they did any
special setup for Open MPI, etc.
But yes, we made a bunch of COMM_SPAWN improvements since the 1.2
series.

The following is the information regarding the error. I am running Open MPI
1.2.5 on Ubuntu 4.2.4, kernel version 2.6.24
I ran the server program as mpirun -np 1 server. This program gave me the
output port as 0.1.0:2000. I used this port name value as the command line
argument for the client program: mpirun -np 1 client 0.1.1:2000.
- The output of the "ompi_info --all" is attached with the email
- PATH Variable:
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr
/local/maui/bin/:
- LD_LIBRARY_PATH variable was empty
- The following is the output of ifconfig on hpcc00 from where the error has
been generated:

I will ask the obvious - what version of Open MPI are you running? In what
environment? What was your command line?
:-)
