   @xinyu-intel Thanks for clarifying my issue/question. 
   
   I have now used Intel MKL yum repo to fine tune the packages to be installed needed by MXnet instead of downloading everything as tar.gz.
   
   https://software.intel.com/en-us/articles/installing-intel-free-libs-and-python-yum-repo
   `sudo yum-config-manager --add-repo https://yum.repos.intel.com/mkl/setup/intel-mkl.repo`
   
   For the record, using the MKL libraries from MRO and installing only the headers from the Intel MKL repo did not work. One needs both the full libraries and headers from the repo. **I do not like this solution since my docker images have redundant MKL library files consuming about ~500 MB.** 
   
   The alternative would be to build R from source and link MKL manually and then build MXnet and link from the installed MKL which would require a very complicated dockerfile.
   
   @pengzhao-intel 
   Looking forward to clearer documentation for full MKL vs MKL-DNN on the MKL readme.
