 Installation of SPACK

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

...

1. Load GCC 7.3.0:

   Code Block
   module load gnu/7.3.0

   
   

2. Prepare directories:

   Code Block

   $: mkdir -p <ROOT_DIR>/{cache,libs,modules,spack,stage}-{<compiler_names>} $: mkdir -p <ROOT_DIR>/cache-{<compiler_names>}/{cache,var,test} $: tree <ROOT_DIR/ <ROOT_DIR>/ ├── cache-compiler_x │   ├── cache │   ├── test │   └── var ├── cache-compiler_y │   ├── cache │   ├── test │   └── var ├── libs-compiler_x ├── libs-compiler_y ├── modules-compiler_x ├── modules-compiler_y ├── spack-compiler_x ├── spack-compiler_y ├── stage-compiler_x └── stage-compiler_y

   
   

3. Clone spack repository to spack-gcc :

   Code Block
   git clone https://github.com/spack/spack.git spack-compiler_name

   
   

4. Go into spack-gcc directory:

   Code Block
   cd spack-compiler_name

   
   

5. Checkout desired version of spack :

   Code Block
   git checkout v0.19.0

   
   

6. Set-up spack configuration:

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

      Code Block
      cd etc/spack/defaults/

      
      

   2. Edit config.yaml :

      Code Block
      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 :

         Code Block
         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: <path_prefix>/<ROOT_DIR>/libs-compiler_name

         
         

      2. projections :

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

         
         

      3. build_stage :

         Code Block
         build_stage: - <path_prefix>/<ROOT_DIR>/stage-compiler_name

         
         

      4. test_stage :

         Code Block
         test_stage: <path_prefix>/<ROOT_DIR>/cache-compiler_name/test

         
         

      5. source_cache :

         Code Block
         source_cache: <path_prefix>/<ROOT_DIR>/cache-compiler_name/var/cache

         
         

      6. misc_cache :

         Code Block
         misc_cache: <path_prefix>/<ROOT_DIR>/cache-compiler_name/cache

         
         

   3. Edit modules.yaml :

      Code Block
      vim modules.yaml

      Change the roots for the tcl modules:

      1. Example: 

         Code Block
         # These are configurations for the module set named "default" default: # Where to install modules roots: tcl:    <path_prefix>/<ROOT_DIR>/modules-compiler_name

         
         

   4. Edit linux/modules.yaml :

      Code Block
      vim linux/modules.yaml

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

      
      

      Code Block
      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

      
      

7. 
   

   Change the directory to the top of the spack repository:

   Code Block
   cd ../../../

   
   

8. Source spack :

   Code Block
   source share/spack/setup-env.sh

   
   

9. Check the spack version - should be 0.19.0 :

   Code Block
   spack --version
