Tutorial setup

If you have not done the prior sections, you’ll need to start the docker image:

docker run -it ghcr.io/spack/tutorial:isc23

and then set Spack up like this:

git clone --depth=100 --branch=releases/v0.20 https://github.com/spack/spack
. spack/share/spack/setup-env.sh
spack tutorial -y
spack bootstrap now
spack compiler find

See the Basic Installation Tutorial for full details on setup. For more help, join us in the #tutorial channel on Slack – get an invitation at slack.spack.io

Stacks Tutorial

So far, we’ve talked about Spack environments in the context of a unified user environment or development environment. But environments in Spack have much broader capabilities. In this tutorial we will consider how to use a specialized sort of Spack environment, that we call a Spack stack, to manage large deployments of software using Spack.

Spec matrices

In a typical Spack environment for a single user, a simple list of specs is sufficient. For software deployment, however, we often have a set of packages we want to install across a wide range of MPIs or compilers. In the following we’ll mimic the creation of a software stack using different libraries for LAPACK and MPI and a compiler for the software which is more recent than the one provided by the system.

Setup the compiler

Let’s create a new anonymous environment and setup the compiler we want to use to build our stack:

$ mkdir -p ~/stacks && cd ~/stacks
$ spack env create -d .
==> Created environment in /home/spack/stacks
==> You can activate this environment with:
==>   spack env activate /home/spack/stacks
$ spack env activate .
$ spack add gcc@12.1.0 %gcc@11.3.0
==> Adding gcc@12.1.0%gcc@11.3.0 to environment /home/spack/stacks
$ spack env view disable
$ spack config edit

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  # add package specs to the `specs` list
  specs:
  - gcc@=12.1.0%gcc@11.3.0
  view: false
  concretizer:
    unify: true

For now, we’ll avoid the view directive. We’ll come back to this later. Let’s concretize and install our compiler:

$ spack concretize -f
$ spack install

Finally, let’s register it as a new compiler in the environment:

$ spack location -i gcc
/home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx
$ spack compiler find "$(spack location -i gcc)"
==> Added 1 new compiler to /home/spack/stacks/spack.yaml
    gcc@=12.1.0
==> Compilers are defined in the following files:
    /home/spack/.spack/linux/compilers.yaml  /home/spack/stacks/spack.yaml

Asking Spack to list the compilers we have available should confirm the presence of gcc@12.1.0:

$ spack compiler list
==> Available compilers
-- clang ubuntu22.04-x86_64 -------------------------------------
clang@=14.0.0

-- gcc ubuntu22.04-x86_64 ---------------------------------------
gcc@=12.1.0  gcc@=11.3.0  gcc@=10.4.0

The manifest file at this point should look like:

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  # add package specs to the `specs` list
  specs:
  - gcc@12.1.0%gcc@11.3.0
  view: false
  concretizer:
    unify: true
  compilers:
  - compiler:
      spec: gcc@=12.1.0
      paths:
        cc: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gcc
        cxx: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/g++
        f77: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gfortran
        fc: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gfortran

      operating_system: ubuntu22.04
      target: x86_64
      modules: []
      environment: {}
      extra_rpaths: []

Note

Setting up a Spack installed compiler for reuse in the same environment is, currently, an iterative process. This requires either to install the compiler first - like done here, or to use more than one environment. An example of the latter approach can be found at this link.

Install software against different MPIs and LAPACKs

Let’s now try to install 4 different versions of netlib-scalapack, compiled with gcc@12.1.0 and linked against different LAPACK and MPI providers. The simplest way to express a cross-product like this in Spack is through a matrix:

$ spack config edit

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  # add package specs to the `specs` list
  specs:
  - gcc@12.1.0%gcc@11.3.0
  - matrix:
    - [netlib-scalapack]
    - [^openmpi, ^mpich]
    - [^openblas, ^netlib-lapack]
    - ["%gcc@12.1.0"]
  view: false
  concretizer:
    unify: false
  compilers:
  - compiler:
      spec: gcc@=12.1.0
      paths:
        cc: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gcc
        cxx: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/g++
        f77: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gfortran
        fc: /home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gfortran
      flags: {}
      operating_system: ubuntu22.04
      target: x86_64
      modules: []
      environment: {}
      extra_rpaths: []

Notice that we have to change the concretizer configuration here. By default, environments co-concretize all specs to be compatible, but that’s simply impossible in an environment with multiple specs for each package. We set the concretizer unification to false to allow all of these builds in one environment:

$ spack concretize
==> Starting concretization pool with 4 processes
==> Environment concretized in 18.35 seconds.
==> Concretized gcc@12.1.0%gcc@11.3.0

The matrix operation does exactly what it looks like it does. It performs the cross-product of the spec constraints appearing in the lists. This allows us to deploy software that will satisfy the expectations of HPC users.

Note

Depending on the use case, for software deployment we can set concretizer unification either to false or to when_possible. The latter option will cause Spack to allow deviations based on the specific abstract specs we requested, but otherwise minimize the proliferation of duplicate specs in the environment.

Finally, we can also exclude some values from a matrix:

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  # add package specs to the `specs` list

Here we constructed a list with both py-scipy ^netlib-lapack and py-scipy ^openblas, and excluded the former from the final output. This example might seem a bit silly right now, where we have a single spec, but it can be really useful to keep configuration file tidy in presence of multiple root specs or when reusing named lists (as we’ll see next).

Let’s concretize the environment and install the specs once again:

$ spack concretize -f
$ spack install

At this point the environment contains only py-scipy ^openblas. Let’s verify it:

$ spack find -l py-scipy

Named lists in spack environments

Spack also allows for named lists in environments. We can use these lists to clean up our example above. These named lists are defined in the definitions key of the spack.yaml file. Our lists today will be simple lists of packages or constraints, but in more complicated examples the named lists can include matrices as well. Let’s clean up our file a bit now:

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  definitions:
    - mpis: [openmpi, mpich]
    - lapacks: [^openblas, ^netlib-lapack]
    - compilers: ["%gcc@12.1.0"]
    - mpi_packages: [netlib-scalapack]
    - serial_packages: [py-scipy]

This syntax may take some time getting used to. Specifically, matrices and references to named lists are always “splatted” into their current position, rather than included as a list object in yaml. This may seem counterintuitive, but it becomes important when we look to combine lists.

Notice that the mpi constraints can be declared as packages and then applied as dependencies using the $^ syntax. The same is true for compilers (using $%), so we’re showing both syntaxes here.

Conditional definitions

Spec list definitions can also be conditioned on a when clause. The when clause is a python conditional that is evaluated in a restricted environment. The variables available in when clauses are:

variable name	value
platform	The spack platform name for this machine
os	The default spack os name and version string for this machine
target	The default spack target string for this machine
architecture	The default spack architecture string platform-os-target for this machine
arch	Alias for architecture
env	A dictionary representing the users environment variables
re	The python re module for regex
hostname	The hostname of this node

Let’s say we only want to limit to just use mpich, unless the SPACK_STACK_USE_OPENMPI environment variable is set. To do so we could write the following spack.yaml:

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  definitions:
    - mpis: [mpich]
    - mpis: [openmpi]

Named lists in the Spack stack are concatenated, so we can define our MPI list in one place unconditionally, and then conditionally append one or more values to it.

Let’s first check what happens when we concretize and don’t set any environment variable:

View descriptors

We told Spack not to create a view for this stack earlier because simple views won’t work with stacks. We’ve been concretizing multiple packages of the same name – they will conflict if linked into the same view.

To work around this, we will use a view descriptor. This allows us to define how each package is linked into the view, which packages are linked into the view, or both. Let’s edit our spack.yaml file again.

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.

The view descriptor also contains a link key, which is either “all” or “roots”. The default behavior, as we have seen, is to link all packages, including implicit dependencies, into the view. The “roots” option links only root packages into the view.

Now we see only the root libraries in the default view. The rest are hidden, but are still available in the full view.

Module files

Module files are another very popular way to let your end users profit from the software you installed. Here we’ll show how you can incorporate the configuration to generate LMod hierarchical module files within the same environment used to install the software.

Note

A more in-depth tutorial, focused only on module files, can be found at Module Files Tutorial. There we discuss the general architecture of module file generation in Spack and we highlight differences between environment-modules and lmod that won’t be covered in this section.

Let’s start by adding lmod to the software installed with the system compiler:

$ spack add lmod%gcc@11.3.0
$ spack concretize
$ spack install

Once that is done, let’s add the module command to our shell like this:

$ . $(spack location -i lmod)/lmod/lmod/init/bash

If everything worked out correctly you should now have the module command available in you shell:

$ module --version

Modules based on Lua: Version 8.7.24  2023-05-04 15:12 -05:00
    by Robert McLay mclay@tacc.utexas.edu

The next step is to add some basic configuration to our spack.yaml to generate module files:

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.

      lmod:
        hierarchy:
        - mpi
        - lapack

In these few lines of additional configuration we told Spack to generate lmod module files in a subdirectory named modules, using a hierarchy comprising both lapack and mpi.

We can generate the module files and use them with the following commands:

$ spack module lmod refresh -y
$ module use $PWD/modules/linux-ubuntu22.04-x86_64/Core

Now we should be able to see the module files that have been generated:

$ module av

If the avail list is too long consider trying:

"module --default avail" or "ml -d av" to just list the default modules.
"module overview" or "ml ov" to display the number of modules for each name.

Use "module spider" to find all possible modules and extensions.
Use "module keyword key1 key2 ..." to search for all possible modules matching any of the "keys".

The sets of modules is already usable, and the hierarchy already works. For instance we can load the gcc compiler and check that we have gcc in out path and we have a lot more modules available - all the ones compiled with gcc@12.1.0:

$ module load gcc
$ which gcc
/home/spack/spack/opt/spack/linux-ubuntu22.04-x86_64_v3/gcc-11.3.0/gcc-12.1.0-s5e5zwrzqozb5e6liaz3tjm6achptgzx/bin/gcc
$ gcc --version

$ module unload gcc

There are a few issues though. For once, we have a lot of modules generated from dependencies of gcc that are cluttering the view, and won’t likely be needed directly by users. Then, module names contain hashes, which go against users being able to reuse the same script in similar, but not equal, environments.

Also, some of the modules might need to set custom environment variables, which are specific to the deployment aspects that don’t enter the hash - for instance a policy at the deploying site.

To address all these needs we can complicate out modules configuration a bit more:

# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
  definitions:
    - mpis: [mpich]
    - mpis: [openmpi]

Let’s regenerate the modules once again:

$ spack module lmod refresh --delete-tree -y
==> Regenerating lmod module files

Now we have a set of module files without hashes, with a correct hierarchy, and with all our custom modifications:

$ module load gcc
$ module load openmpi openblas netlib-scalapack py-scipy
$ module av
