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

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

Hi,
I have been trying to execute the server.c and client.c program provided in
http://www.mpi-forum.org/docs/mpi21-report/node213.htm#Node213, using
accept() and connect() function in MPI. However, the following errors are
