Spack Extension

Extension of spack command in spack-stack

This section describes the spack stack extension of the spack command, which simplifies the installation process. The spack stack extension is automatically registered with Spack when sourcing spack-stack's setup.sh script. As for any other spack command, help is available with spack stack -h. The spack stack extension has two subcommands, explained in the following.

spack stack [create|setup-meta-modules]

The spack stack create command creates a new environment or a new container.

spack stack create [env|ctr]

The full list of options for creating environments is available by running

spack stack create env --help

Note. At the time of writing the container creation is not supported. Do not use spack stack create ctr.

Following a successful creation of an environment (not a container), and the generation of the spack lmod/tcl module files via spack module [lmod|tcl] refresh, the meta modules for the compiler and MPI library are generated with

spack stack setup-meta-modules

This command takes no arguments; it completes the environment generation and creates a Core directory that must be added to the module path (module use .../Core) as shown in numerous other places in the documentation.
