1.  Installation of SPACK

TODO: This section should contain all the information related to:

• installation of SPACK
• configuration of SPACK environment
• setting up target location of SPACK based distribution

2. Marconi + SPACK + GNU

This instruction covers all actions and commands from logging into the Marconi server to installing imasenv.

1. Logging into the Marconi :

   ssh <USER_NAME>@login.marconi.cineca.it

2. Change location to $WORK directory, which should point to /marconi_work/FUSIO_HLST :

   $: cd $WORK
   $: pwd
   /marconi_work/FUSIO_HLST

3. Prepare directories:

   $: mkdir -p IMAS_software/{cache,libs,modules,spack,stage}-{gcc,intel}
   $: mkdir -p IMAS_software/cache-{gcc,intel}/{cache,var,test}
   $: tree IMAS_software/
   IMAS_software/

   │   ├── cache
   │   ├── test
   │   └── var
   ├── cache-intel
   │   ├── cache
   │   ├── test
   │   └── var

   ├── libs-intel
   ├── modules-gcc
   ├── modules-intel
   ├── spack-gcc
   ├── spack-intel
   ├── stage-gcc
   └── stage-intel

4. Clone spack repository to spack-gcc :

   git clone https://github.com/spack/spack.git spack-gcc

5. Go into spack-gcc directory:

   cd spack-gcc

6. Checkout desired version of spack :

   git checkout v0.19.0

7. Set-up spack configuration:

   1. Go to directory where default configuration files are stored (assuming you're still inside spack-gcc repository):

      cd etc/spack/defaults/

   2. Edit config.yaml :

      vim config.yaml

      You need to change the root of the install_tree, projections for all, build_stage dir, test_stage dir, source_cache dir and misc_cache dir.
      Example:

      1. root of the install_tree :

         config:
           # This is the path to the root of the Spack install tree.
           # You can use $spack here to refer to the root of the spack instance.
           install_tree:
             root: /marconi_work/FUSIO_HLST/IMAS_software/libs-gcc

      2. projections :

         projections:
               all: "${PACKAGE}/${VERSION}/${COMPILERNAME}/${COMPILERVER}/${HASH}"

      3. build_stage :

           build_stage:
             - /marconi_work/FUSIO_HLST/IMAS_software/stage-gcc

      4. test_stage :

           test_stage: /marconi_work/FUSIO_HLST/IMAS_software/cache-gcc/test

      5. source_cache :

           source_cache: /marconi_work/FUSIO_HLST/IMAS_software/cache-gcc/var/cache

      6. misc_cache :

           misc_cache: /marconi_work/FUSIO_HLST/IMAS_software/cache-gcc/cache

   3. Edit modules.yaml :

      vim modules.yaml

      Change the roots for the tcl modules:

      1. Example: 

           # These are configurations for the module set named "default"
           default:
             # Where to install modules
             roots:
              tcl:    /marconi_work/FUSIO_HLST/IMAS_software/modules-gcc

   4. Edit linux/modules.yaml :

      vim linux/modules.yaml

      Here you have to fill the whole body just to set the module structure projections:

      modules:
        default:
          arch_folder: false
          tcl:
            projections:
              all: '{name}/{version}/{compiler.name}/{compiler.version}/sha'
          prefix_inspections:
            lib:
              - LD_LIBRARY_PATH
            lib64:
              - LD_LIBRARY_PATH

8. Change the directory to the top of the spack repository:

   cd ../../../
   

9. Source spack :

   source share/spack/setup-env.sh

10. Check the spack version - should be 0.19.0 :

    spack --version

11. Install Lapack :

    spack install netlib-lapack %gcc@7.3.0 cflags="-fPIC" cxxflags="-fPIC" cppflags="-fPIC"

12. Install Blas :

    spack install -j 1 netlib-xblas %gcc@7.3.0 cflags="-fPIC" cxxflags="-fPIC" cppflags="-fPIC"

13. Install Python with tkinter support:

    spack install python@3.9.15 +tkinter %gcc@7.3.0 cflags="-fPIC" cxxflags="-fPIC" cppflags="-fPIC"

14. Install py-scipy :

    spack install --fail-fast py-scipy %gcc@7.3.0 cflags="-fPIC" cxxflags="-fPIC" cppflags="-fPIC"

15. Install
