1. Profile should be established this umask  will be required later in the stack install as will the ulimit  settings
   

   Code Block
   language shell
   # .bash_profile umask 0022 ulimit -S -s unlimited if [[ ~/.bashrc ]]; then . ~/.bashrc fi cd ~

   
   
2. Follow the instructions for Prerequisites for Ubuntu (one-off): 
   1. apt install -y gcc-13 g++-13 gfortran-13 gdb
   1. gcc –version
   2. https://spack-stack.readthedocs.io/en/latest/NewSiteConfigs.html#prerequisites-ubuntu-one-off
   3. When installing the gcc compilers, make sure you install version 13
   4. Check that you have the links for the gcc compilers installed, and that the version is 13.x
3. Follow the instructions for creating a new environment:   https://spack-stack.readthedocs.io/en/latest/NewSiteConfigs.html#newsiteconfigs-linux-createenv 
   1. Step 1: For now use the 1.9.0 release branch when cloning spack-stack (Place the spack-stack clone in you home directory
    git clone -b release/
   2. .)
      

      Code Block
      language shell
      git clone -b release/1.9.0 --recurse-submodules https://github.com/jcsda/spack-stack.git

   3. cd spack

   stack create env --site linux.default --template unified-dev --name

   4. -stack # Sources Spack from submodule and sets ${SPACK_STACK_DIR} source setup.sh

   5. Step 2: Create a unified-dev environment - complete step following newsiteconfigs 
      

      Code Block
      language shell
      spack stack create env --site linux.default --template unified-dev --name unified-env.gcc --compiler=

   gcc
   1. In the section where you are adding the compiler and mpi to the config, use (example is based on “gcc –version” returning 13.3.0)
   1. spack config add "packages:all:compiler:[gcc@13.3.0]"
   2. spack config add "packages:all:providers:mpi:[openmpi@5.0.5]"
1. https://spack-stack.readthedocs.io/en/latest/NewSiteConfigs.html#newsiteconfigs-linux-createenv
2. Step 1: For now use the 1.9.0 release branch when cloning spack-stack
3. Step 2: Create a unified-dev environment
4. Step 5: Check that “spack compiler find --scope system” reports version 13.x
5. Step 7: Use openmpi 5.0.5 instead of mpich
6. Step 9: Leave the module configuration as is (tcl), so skip this step

4. 1. gcccd envs/unified-env.gcc/ spack env activate [-p] .

   2. Step 3: follow newsiteconfigs 
   3. Step 4: follow newsiteconfigs 
   4. Step 5: Check that “spack compiler find --scope system” reports version 13.x)
   5. Step 6: follow newsiteconfigs 
   6. Step 7:  Use openmpi 5.0.5, can skip  add of mpich.  

      1. 1. Code Block
            language shell
            gcc --version#presume gcc v13.3.0 herespack config add "packages:all:compiler:[gcc@13.3.0]"

         2. Code Block
            language shell
            # openmpi v5.0.5 skip mpich install spack config add "packages:all:providers:mpi:[openmpi@5.0.5]"

   7. Step 8: follow newsiteconfigs 
   8. Step 9: skip - if new Orbstack 
   9. Step 10: skip - if new Orbstack
   10. Step 11: concretize and install: follow newsiteconfigs
