The reason is that you aren't actually running Open MPI - those error messages are coming from MPICH. Check your path and ensure you put the OMPI install location first, or use the absolute path to the OMPI mpirun

I have built open mpi 1.6 with Intel compilers (2013 versions). Compilation was smooth, however even when I try to execute

Before that, there was an additional error, since also the file was not present in /opt/intel/composer_xe_2013.0.079/mpirt/bin/intel64/.
Even though I managed to create one and it worked:


if [ -z "`echo $PATH | grep /usr/local/bin`" ]; then
export PATH=/usr/local/bin:$PATH

if [ -z "`echo $LD_LIBRARY_PATH | grep /usr/local/lib`" ]; then
if [ -n "$LD_LIBRARY_PATH" ]; then
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/lib

I do not have any clue about how to generate the file pmi_proxy.

Thank you in advance for your help!
