Subject: [OMPI users] mpirun error output
From: Bruno Cramer (bruno.cramer_at_[hidden])

1) Openmpi in PC1

I installed openmpi-1.4.3 using the OpenSuse 32b v. 12.1 repository

as well as openmpi devel

All mpi executables are present so are the libraries in lib directory.

I set the environment as ( .bashrc)



export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/mpi/gcc/openmpi/lib

export PATH

 When I run any of the test examples (eg. mpirun hello_c.c or any program
that has mpi interface included I get the message


mpirun was unable to launch the specified application as it could not find
an executable:

Executable: hello_c.c

Node: linux-curie

while attempting to start process rank 0.


typing echo $LD_LIBRARY_PATH I should get something like
/usr/lib/mpi/gcc/openmpi/lib. The only output I get is
/usr/local/atlas3.10/lib (which is the blas/lapack library). Also Intel
compilers library is not shown.

1) Openmpi installation in PC2

In OpenSuse v 12.1 64b I installed openmpi-1.4.3 downloading it from the
openmpi site.

No error occured during ./configure, make, make install process.

The environment settings change a little but are very similar to those
mentioned under PC1.

The same message as above is occuring.

in this case typing echo $LD_LIBRARY_PATH I get the correct output from the
mpi library as /usr/local/lib64 and the executables are in /usr/local/bin.

Any help is wellcome
