Yes. As I indicated earlier, I did use these options to compile my program
MPI_CXX=/programs/openmpi/bin/mpicxx
MPI_CC=/programs/openmpi/bin/mpicc
MPI_INCLUDE=/programs/openmpi/include/
MPI_LIB=mpi /programs/openmpi/
MPI_LIBDIR=/programs/openmpi/lib/
MPI_LINKERFORPROGRAMS=/programs/openmpi/bin/mpicxx
where /programs/openmpi/ is the chosen location for installing the openmpi
package (specifically, openmpi-1.3.tar.gz) that I downloaded from
www.open-mpi.org.
Any clue? Again, my system is Suse 10.3 64-bit, which should be pretty
standard. Would another package openmpi-1.3-1.src.rpm work better for my system?
Thanks,
JO

Did you try compiling your program with the provided mpicc (or mpiCC, mpif90,
etc. - as appropriate) wrapper compiler? The wrapper compilers contain all the
required library definitions to make the application work.
Compiling without the wrapper compilers is a very bad idea...

Please let me go over it again, and maybe it helps clarifying things a bit
better. All the OS involved are Suse 10.3.
I have a place for the the installed programs, say /programs.
In /programs I have installed openmpi and my mpi program, say my_mpi_program.
When I am in the working directory, my LD_LIBRARY_PATH does include both
/programs/my_mpi_program/lib
/programs/openmpi/lib
And my PATH includes
/programs/my_mpi_program/bin
/programs/openmpi/bin
So, then I do
mpirun -machinefile machinefile -np 20 my_mpi_program <arguments>
and I get
/programs/my_mpi_program: symbol lookup error:
/programs/openmpi/lib/libmpi_cxx.so.0: undefined symbol:
ompi_registered_datareps
When I configured openmpi, I did
./configure --prefix=/programs/openmpi
and then compiled it. Subsequently, I compiled my_mpi_program with the options:
MPI_CXX=/programs/openmpi/bin/mpicxx
MPI_CC=/programs/openmpi/bin/mpicc
MPI_INCLUDE=/programs/openmpi/include/
MPI_LIB=mpi
MPI_LIBDIR=/programs/openmpi/lib/
MPI_LINKERFORPROGRAMS=/programs/openmpi/bin/mpicxx
Any clue? The directory /programs is NSF mounted on the nodes.
Many thanks again,
JO

Hi Ralph:
Sorry for my ignorance, but in you option 2: what command should I add the
option
--prefix=path-to-install? when I configure openmpi? I already did that when I
configured and compiled openmpi. Also, in response to your option 1, I did
add the paths to libraries of openmpi in the LD_LIBRARY_PATH in the .cshrc of
the nodes.
Thank you,
JO

First, you can add --launch-agent rsh to the command line and that will have
OMPI use rsh.
It sounds like your remote nodes may not be seeing your OMPI install directory.
Several ways you can resolve that - here are a couple:
1. add the install directory to your LD_LIBRARY_PATH in your .cshrc (or
whatever shell rc you are using) - be sure this is being executed on the remote
nodes
2. add --prefix=path-to-install on your cmd line - this will direct your remote
procs to the proper libraries

Maybe I should also add that the program
my_mpi_executable is locally installed under the same root directory as that
under which openmpi-1.3 is installed. This root directory is NSF mounted on
the working nodes.

Hi Ralph:
Thanks for your prompt response. I am using openmpi-1.3, Suse 10.3. I installed
openmpi-1.3 with the option
./configure --prefix=/where/to/install
and then just
make all install
I thought the default connection mode is rsh, but I had to invoke ssh-agent, in
order not have to enter password one by one. How to change to rsh?
Thanks,
JO

Could you tell us what version of Open MPI you are using, a little about your
system (I would assume you are using ssh?), and how this was configured?
ThanksRalph
