 - Often it may be useful to integrate the accelerated OpenACC code with
   other accelerated libraries
 - MPI,  CUBLAS, CUFFT, MAGMA, CULA...
 - to mix OpenACC and CUDA:
     - Use OpenACC for memory management
     - Introduce OpenACC in existing GPU code
     - Use CUDA for tightest kernels, otherwise OpenACC
