Hi folks, I am testing our cluster with module environment, and am having a headache to understand openmpi 1.7.2!!! So our system currently has openmpi 1.6.3 (at default location /usr/local), 1.6.4 and 1.7.2 compiled with intel compilers (installed at /opt/apps). In order to use openmpi 1.7.2 for example, I tried:
$ module load mpi/openmpi-1.7.2_composer_xe_2013.3.163 $ module load apps/abinit-7.2.1_composer_xe_2013.3.163_openmpi-1.7.2_intel_fftw3-mkl $ mpirun ./mpihello_intel mca: base: component_find: unable to open /usr/local/lib/openmpi/mca_ess_hnp: /usr/local/lib/openmpi/mca_ess_hnp.so: undefined symbol: orte_local_jobdata (ignored) mca: base: component_find: unable to open /usr/local/lib/openmpi/mca_ess_slurm: /usr/local/lib/openmpi/mca_ess_slurm.so: undefined symbol: orte_orted_exit_with_barrier (ignored) mca: base: component_find: unable to open /usr/local/lib/openmpi/mca_ess_slurmd: /usr/local/lib/openmpi/mca_ess_slurmd.so: undefined symbol: orte_pmap_t_class (ignored) mpirun: symbol lookup error: /usr/local/lib/openmpi/mca_ess_singleton.so: undefined symbol: orte_util_setup_local_nidmap_entries To investigate the error, I tried: $ echo $LD_LIBRARY_PATH /opt/apps/abinit/abinit-7.2.1_composer_xe_2013.3.163_openmpi-1.7.2_intel_fftw3-mkl/usr/local/lib:/opt/apps/openmpi/openmpi-1.7.2r28341_composer_xe_2013.3.163/usr/local/lib/openmpi:/opt/apps/openmpi/openmpi-1.7.2r28341_composer_xe_2013.3.163/usr/local/lib:/usr/local/lib:/opt/intel/lib/intel64:/opt/intel/mkl/lib/intel64 $ ls /opt/apps/openmpi/openmpi-1.7.2r28341_composer_xe_2013.3.163/usr/local/lib/openmpi | grep mca_ess mca_ess_env.la mca_ess_env.so mca_ess_hnp.la mca_ess_hnp.so mca_ess_singleton.la mca_ess_singleton.so mca_ess_slurm.la mca_ess_slurm.so mca_ess_tm.la mca_ess_tm.so mca_ess_tool.la mca_ess_tool.so So apparently openmpi 1.7.2 looks for the old library at /usr/loca/lib/openmpi for 1.6.3 instead of at /opt/apps/openmpi/openmpi-1.7.2r28341_composer_xe_2013.3.163/usr/local/lib/openmpi. Is there away to force openmpi 1.7.2 look at /opt/apps/openmpi/openmpi-1.7.2r28341_composer_xe_2013.3.163/usr/local/lib/openmpi first before looking at other locations? Thanks, D.
