   I cannot comment for using the core MKL library, but to use the MKL2017 and  MKL2017 Experimental you will need to do the following: 
   1. Build the mxnet library with USE_MKL2017 = 1 and USE_MKL2017_EXPERIMENTAL = 1
   2. Prior to make the R library (sudo make rpkg), create static links to the MKL libraries: 
   ```
   ln -s /usr/local/lib/libiomp5.so /lib/libiomp5.so
   ln -s /usr/local/lib/libmklml_gnu.so /lib/libmklml_gnu.so \
   ln -s /usr/local/lib/libmklml_intel.so /lib/libmklml_intel.so
   ```
   The above works seemlessly, building process take cares of downloading the MKL2017 libraries. 
   
   Not sure of the added benefits of using MKL instead of openblas if the MKL2017 and Experimental and enabled, but you'll need to modify some parameters in the `make/config.mk`, look also at: `MKL_README.md`
