 ### Build MXNet with MKL-DNN
 
+To achieve better performance, the Intel OMP and llvm OMP are recommended as below instruction.
Otherwise, default GOMP will be used and you may get the sub-optimal performance. If you don't
have the full [MKL](https://software.intel.com/en-us/intel-mkl) library installation, you
might use OpenBLAS as the blas library, by setting USE_BLAS=openblas.
 
 Review comment:
   cmake will build and link llvm-omp in 3rdparty/openmp automatically and makefile temporary
not support.
