Problem with running program on mic

Hello,

I trying a run a simple file-open program on mic0 but the program fails (does not open file but terminates gracefully!) when i run it from the host machine and succeeds (program opens the file on mic0))when i run it directly from the mic card

I have cleared the firewalls, and i do

I_MPI_MIC = enable

% scp /opt/intel/impi/4.1.1.036/mic/bin/pmi_proxy mic0:/bin

% scp /opt/intel/impi/4.1.1.036/mic/lib/* mic0:/lib64/.

here is my run command:-

/opt/intel/impi/4.1.1.036/bin64/mpirun -host mic0 -n 1 ~/a.out

 thanks for the help in advance
