2) Compiling hycom_all under NERSC-HYCOM-CICE/hycom/hycom_ALL/hycom_2.2.72_ALL

   # Define "setenv ARCH intelIFC" in Make_all.src
   csh Make_all.com

   !! NOT COMPLETE
	The csh script above does not complete because it gets stuck in archive folder.
        Normally it should fail and continue but not this time.
        You can compile each folder individually for the time being until the problem is resolved.

        Netcdf routines are partly compiled right, 
        csh Make_ncdf.com

        but for someones are interested,
        
3) Compiling MSCPROGS under NERSC-HYCOM-CICE/hycom/MSCPROGS/src

       Go to NERSC-HYCOM-CICE/hycom/MSCPROGS/src/Make.Inc/
       execute:
          ln -s make.betzy.ifort make.inc
          cd ../
          gmake clean
          gmake all
          gmake install

4) Compiling hycom_cice under TP0a1.00/expt_01.0

   compile_model.sh ifort -u

   
5) prepare the python tools on Betzy
