## page was renamed from Jureca/Libraries_ifort19
== Install Libraries on JURECA with ifort 19.0.0, gcc 7.3.0 and Parastation MPI ==

The libraries used by CLaMS are installed in directory /homec/jicg11/jicg1108

=== load modules ===
 {{{
module purge
module load intel-para
module load netCDF-Fortran
}}}

=== create new directories ===
 {{{
mkdir clams_lib_ifort19.0.0
mkdir clams_mod_ifort19.0.0
mkdir clams_lib_mpi_ifort19.0.0
mkdir clams_mod_mpi_ifort19.0.0
}}}

=== qhull ===

Possibly the name of the C-routine ''qhull_dll'' in file ''unix.c'' must be adjusted:  for gcc it must be '''qhull_dll_''' !

 {{{
cd ~/qhull
make new  
mv libqhull.a libqhull_gcc7.3.0.a

cd ~/clams_lib_ifort19
ln -sf ../qhull/libqhull_gcc7.3.0.a ./libqhull.a

cd ~
chmod -R 755 qhull
}}}


=== numrec ===

 {{{
cd ~/numrec-f90

mkdir lib_ifort19.0.0
mkdir mod_ifort19.0.0
mkdir obj_ifort19.0.0
}}}

 in Makefile.numrec:
  {{{
   F90 = ifort
   objDir = obj_ifort19.0.0
   modDir = mod_ifort19.0.0
   libDir = lib_ifort19.0.0
}}}

 {{{
make -f Makefile.numrec  new
}}}

 {{{
cd ~/clams_lib_ifort19
ln -sf ../numrec-f90/lib_ifort19.0.0/libnumrec.a .

cd ~/clams_mod_ifort19
ln -sf ../numrec-f90/mod_ifort19.0.0/nr.mod .
ln -sf ../numrec-f90/mod_ifort19.0.0/nrtype.mod .
ln -sf ../numrec-f90/mod_ifort19.0.0/nrutil.mod .

cd ~
chmod -R 755 numrec-f90
}}}

=== netcdf ===

 * Netcdf is installed on Jureca for different C and Fortran compiler versions.

 * If the netcdf module is loaded, "ncdump" and "ncgen" can be used and compilation of programs using netcdf is possible (without specifying any library or include paths).

 * Compile Fortran program with NetCDF:
 {{{
ifort -o progname progname.f90 -lnetcdff -lnetcdf -lhdf5_hl -lhdf5 -lz
}}}

 * After loading the netcdf module the following environment variables are expanded:
   * '''PATH''' includes directory with netcdf binaries (ncdump)
   * '''CPATH''' includes directory with include-files and netcdf-modules
   * '''LD_LIBRARY_PATH''' includes directories with all needed libraries (netcdf, hdf5, zlib etc)


=== utils ===


 Following files were adapted:
  * utils-cf/Makefile
  * mkincl/platform.mk
  * mkincl/config/config.Linux_ifc

 * Serial version of library:
 {{{
cd ~/utils-cf

make theLibrary

cd ~/clams_lib_ifort19
ln -sf ../utils-cf/lib_linux_ifc_19.0.0.117/libutils-icg1.a .

cd ~/clams_mod_ifort19
ln -sf ../utils-cf/mod_linux_ifc_19.0.0.117/* .

cd ~
chmod -R 755 utils-cf
}}}

 * MPI version of library:
 {{{
cd ~/utils-cf

make useMPI=true theLibrary

cd ~/clams_lib_mpi_ifort19
ln -sf ../utils-cf/lib_linux_ifc_19.0.0.117_mpi/libutils-icg1.a .

cd ~/clams_mod_mpi_ifort19
ln -sf ../utils-cf/mod_linux_ifc_19.0.0.117_mpi/* .

cd ~
chmod -R 755 utils-cf
}}}

=== set new links ===
 {{{
rm clams_lib clams_mod clams_lib_mpi clams_mod_mpi
ln -sf clams_lib_ifort19.0.0 clams_lib
ln -sf clams_mod_ifort19.0.0 clams_mod
ln -sf clams_lib_mpi_ifort19.0.0 clams_lib_mpi
