hi Stefano your error message show that you are missing a shared library, not necessary that library path is wrong.
do you actually have libimf.so, can you find the file on your system. ./Thomas From: Stefano Zaghi <stefano.za...@gmail.com> To: us...@open-mpi.org, List-Post: users@lists.open-mpi.org Date: 21.06.2013 09:27 Subject: [OMPI users] OpenMPI 1.6.4 and Intel Composer_xe_2013.4.183: problem with remote runs, orted: error while loading shared libraries: libimf.so Sent by: users-boun...@open-mpi.org Dear All, I have compiled OpenMPI 1.6.4 with Intel Composer_xe_2013.4.183. My configure is: ./configure --prefix=/home/stefano/opt/mpi/openmpi/1.6.4/intel CC=icc CXX=icpc F77=ifort FC=ifort Intel Composer has been installed in: /home/stefano/opt/intel/2013.4.183/composer_xe_2013.4.183 Into the .bashrc and .profile in all nodes there is: source /home/stefano/opt/intel/2013.4.183/bin/compilervars.sh intel64 export MPI=/home/stefano/opt/mpi/openmpi/1.6.4/intel export PATH=${MPI}/bin:$PATH export LD_LIBRARY_PATH=${MPI}/lib/openmpi:${MPI}/lib:$LD_LIBRARY_PATH export LD_RUN_PATH=${MPI}/lib/openmpi:${MPI}/lib:$LD_RUN_PATH If I run parallel job into each single node (e.g. mpirun -np 8 myprog) all works well. However, when I tried to run parallel job in more nodes of the cluster (remote runs) like the following: mpirun -np 16 --bynode --machinefile nodi.txt -x LD_LIBRARY_PATH -x LD_RUN_PATH myprog I got the following error: /home/stefano/opt/mpi/openmpi/1.6.4/intel/bin/orted: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory I have read many FAQs and online resources, all indicating LD_LIBRARY_PATH as the possible problem (wrong setting). However I am not able to figure out what is going wrong, the LD_LIBRARY_PATH seems to set right in all nodes. It is worth noting that in the same cluster I have successful installed OpenMPI 1.4.3 with Intel Composer_xe_2011_sp1.6.233 following exactly the same procedure.
