Hello, 

Which the exact version of the Linpack, Intel MKL, intel compiler and mpi? what command setting when you run the benchmark?

Are you running the binary code from MKL install directory, for example ~/intel/compilers_and_libraries_2016.0.069/linux/mkl/benchmarks/linpack

or download from 

https://software.intel.com/en-us/articles/intel-math-kernel-library-linpack-download/? ;

Could you please attach the log?

Best Regards,

Ying
