OK one of my settings is wrong.  I can not figure out which one it is.  When I enter:  "mpirun -hosts mic0 -np 128 ./a.out"  I get an error /packages/intel/compilers_and_libraries_2016.3.210/linux/mpi/intel64/bin/pmi_proxy:  No such file or directory. 

I have the following settings on the host:  

env | grep MPI
I_MPI_ROOT=/usr/local/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi

echo $I_MPI_MIC enable env | grep -i mpi MANPATH=/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi/man:/packages/intel/16/linux/man/en_US:/usr/share/man LD_LIBRARY_PATH=/usr/local/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi/mic/lib:./:/usr/local/packages/intel/16/linux/mkl/lib/intel64:/usr/local/packages/intel/16/linux/compiler/lib/intel64:/usr/local/packages/intel/16/linux/mpirt/lib/intel64:/usr/local/packages/intel/16/linux/ipp/lib/intel64:/usr/local/packages/intel/16/linux/tbb/lib/intel64:/usr/local/packages/intel/impi/5.1/intel64/lib PATH=/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi/intel64/bin:/packages/intel/16/linux/bin/intel64:/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/users/dmackay/bin LOADEDMODULES=mpi/intel-5.1:intel/16 If I ssh onto the mic card: ssh mic0 dmackay@system-mic0:~$ ls /usr/local/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi/ or ls /usr/local/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi/mic/bin IMB-MPI1 hydra_nameserver mpiexec mpifc mpiicpc mpivars.sh IMB-NBC mpicc mpiexec.hydra mpigcc mpiifort pmi_proxy IMB-RMA mpicleanup mpif77 mpigxx mpirun tune cpuinfo mpicxx mpif90 mpiicc mpivars.csh ssh mic0 I_MPI_ROOT=/usr/local/packages/intel/compilers_and_libraries_2016.3.210/linux/mpi So why is the MIC card looking in the intel64 bin? What env setting do I have wrong?

Hi David,

Could you please specify the exact reproducer (with all Intel MPI environment variables you set)?

Thank you Artem,

Difficulty cutting and pasting into these forum editing boxes (but you saw that I had problem editing in the first box submission).   I have things working now.   My environment settings were wrong.   Notice in my original posting when I entered echo $I_MPI_MIC I got the correct result - "enable"   but also notice that when I entered "env | grep -i mpi" I_MPI_MIC was not part of the environment settings!   My script setting this was configured wrong.   When I corrected the script setting my environment and then enter "env | grep -i mpi" I_MP_MIC is part of the environment settings (and other things).     Things are working correctly for me now thank you.
