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:hpcic25
and then set Spack up like this:
git clone --depth=2 --branch=releases/v1.0 https://github.com/spack/spack
. spack/share/spack/setup-env.sh
spack repo update builtin --tag v2025.07.0
spack mirror add --unsigned tutorial /mirror
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
Warning
The spack tutorial -y command is intended for use in a container or VM.
Use with care in other environments since it replaces some configuration files in order to establish suitable settings for the tutorial.
Stacks Tutorial¶
We’ve talked about Spack environments in the context of a unified user environment. But environments in Spack have much broader capabilities. In this tutorial we will consider how to use Spack environments to manage large deployments of software.
What usually differs between a typical environment for a single user, and an environment used to manage large deployments, is that in the latter case we often have a set of packages we want to install across a wide range of MPIs, LAPACKs or compilers.
Below, we’ll mimic the creation of a software stack built onto a cross-product of different LAPACK and MPI libraries, with a compiler that is more recent than the one provided by the host system.
First, we’ll focus on how to properly configure and install the software we want. We’ll learn how to pin certain requirements, and how to write a cross product of specs in a compact, and expressive, way.
We’ll consider how the software we install might be consumed by our users, and see the two main mechanisms that Spack provides for that: views and module files.
Note
Before we start this hands-on, make sure the EDITOR environment variable is set to your
preferred editor, for instance:
$ export EDITOR='emacs -nw'
Setup the compiler¶
The first step to build our stack is to setup the compiler we want to use later. This is currently an iterative process that can be done in two ways:
Install the compiler first, then install the rest of the environment
Install the compiler outside the environment (either in another environment or standalone)
Below, we’ll use the first approach. For people interested, an example of composing a compiler from another environment can be found at this link.
Let’s start by creating an environment in a directory of our choice:
$ spack env activate --create ~/stacks
$ spack env status
==> In environment /home/spack/stacks
We can add from the command line a new compiler. We’ll also disable the generation of views for the time being, as we’ll come back to this topic later in the tutorial:
$ spack add gcc@12 %gcc@11
==> Adding gcc@12 %gcc@11 to environment /home/spack/stacks
$ spack env view disable
$ spack config edit
What you should see on screen now is the following spack.yaml file:
# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
specs:
- gcc@12%gcc@11
view: false
concretizer:
unify: true
The next step is to concretize and install our compiler:
$ spack concretize
==> Concretized 1 spec:

We are ready to build more software with our newly installed GCC!
Install a software stack¶
Now that we have a compiler ready, the next objective is to build software with it.
We’ll start by trying to add different versions of netlib-scalapack, linked against different MPI implementations:
$ spack add netlib-scalapack %gcc@12 ^openblas ^openmpi
==> Adding netlib-scalapack %gcc@12 ^openblas ^openmpi to environment /home/spack/stacks
$ spack add netlib-scalapack %gcc@12 ^openblas ^mpich
==> Adding netlib-scalapack %gcc@12 ^mpich ^openblas to environment /home/spack/stacks
If we try to concretize the environment, we’ll get an error. We cannot unify an environment with two different configurations of the same package.
Tuning concretizer options for a stack¶
Whenever we concretize an environment with more than one root spec, we can configure Spack to be more or less strict with duplicate nodes in the sub-DAG obtained by following link and run edges starting from the roots. We usually call this sub-DAG the root unification set.
A diagram might help visualize the concept:
The image above represents the current environment, with our three root specs highlighted by a thicker dashed line. Any node that could be reached following a link or run edge is part of the root unification set. Pure build dependencies might fall outside of it.
The config option determining which nodes are allowed to be in the root unification set is concretizer:unify.
Let’s check its value:
$ spack config get concretizer | grep unify
unify: true
concretizer:unify:true means that only a single configuration for each package can be present.
This value is good for single project environments, since it ensures we can construct a view of all the software, with the usual structure expected on a Unix-ish system, and without risks of collisions between installations.
We can’t respect this requirement, as our roots already contain two different configurations of netlib-scalapack.
Set the value to false, and try to re-concretize:
$ spack config add concretizer:unify:false
$ spack concretize
==> Starting concretization pool with 2 processes
==> Concretized 2 specs:

This time concretization succeeded.
Setting concretizer:unify:false is effectively concretizing each root spec on its own, and then merging the results into the environment.
This allows us to have the duplicates we need.
Note
If the environment is expected to have only a few duplicate nodes, then there’s another value we might consider:
$ spack config add concretizer:unify:when_possible
With this option Spack will try to unify the environment in an eager way, solving it in multiple rounds.
The concretization at round n will contain all the specs that could not be unified at round n-1, and will consider all the specs from previous rounds for reuse.
Spec matrices¶
Let’s further expand our stack and consider also linking against different LAPACK providers. We could, of course, add new specs explicitly:
$ spack add netlib-scalapack %gcc@12 ^netlib-lapack ^openmpi
==> Adding netlib-scalapack %gcc@12 ^netlib-lapack ^openmpi to environment /home/spack/stacks
$ spack add netlib-scalapack %gcc@12 ^netlib-lapack ^mpich
==> Adding netlib-scalapack %gcc@12 ^mpich ^netlib-lapack to environment /home/spack/stacks
This way of proceeding, though, will become very tedious once more software is requested. The best way to express a cross-product like this in Spack is instead through a matrix:
# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.
spack:
specs:
- gcc@12%gcc@11
- matrix:
- [netlib-scalapack]
- [^openmpi, ^mpich]
- [^openblas, ^netlib-lapack]
- ["%gcc@12"]
view: false
concretizer:
unify: false
Matrices will expand to the cross-product of their rows, so this matrix:
- matrix:
- ["netlib-scalapack"]
- ["^openmpi", "^mpich"]
- ["^openblas", "^netlib-lapack"]
- ["%gcc@12"]
is equivalent to this list of specs:
- "netlib-scalapack %gcc@12 ^openblas ^openmpi"
- "netlib-scalapack %gcc@12 ^openblas ^mpich"
- "netlib-scalapack %gcc@12 ^netlib-lapack ^openmpi"
- "netlib-scalapack %gcc@12 ^netlib-lapack ^mpich"
We are now ready to concretize and install the environment:

As we can see we have our four variations of netlib-scalapack installed.
Reusable definitions¶
So far, we have seen how we can use spec matrices to generate cross-product specs from rows containing a list of constraints. A common situation you will encounter with large deployments is the necessity to add multiple matrices to the list of specs, that possibly share some of those rows.
To reduce the amount of duplication needed in the manifest file, and thus the maintenance burden for people maintaining it, Spack allows to define lists of constraints under the definitions attribute, and expand them later when needed.
Let’s rewrite our manifest accordingly:
# 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" ]
- mpi_packages: [ netlib-scalapack ]
specs:
- gcc@12%gcc@11
- matrix:
- [$mpi_packages]
- [$^mpis]
- [$^lapacks]
- [$%compilers]
view: false
concretizer:
unify: false
Check that re-concretizing won’t change the environment:
$ spack concretize
==> No new specs to concretize.
$ spack find -l
==> In environment /home/spack/stacks
==> 5 root specs

Now we can use those definitions to add e.g. serial packages built against the LAPACK libraries.
Let’s try to do that by using py-scipy as an example:
Another useful ability is excluding specific entries from a cross-product matrix.
We can do that with the exclude keyword, in the same item as the matrix.
Try to remove py-scipy ^netlib-lapack from our matrix:
# This is a Spack Environment file.
#
# It describes a set of packages to be installed, along with
# configuration settings.

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 |
|---|---|
|
The spack platform name for this machine |
|
The default spack os name and version string for this machine |
|
The default spack target string for this machine |
|
The default spack architecture string platform-os-target for this machine |
|
Alias for |
|
A dictionary representing the users environment variables |
|
The python |
|
The hostname of this node |
Suppose we want to limit usage to only 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]
when: 'env.get("SPACK_STACK_USE_OPENMPI", "") == "1"'
- lapacks: [ openblas, netlib-lapack ]
- compilers: [ "gcc@12" ]
- mpi_packages: [ netlib-scalapack ]
- serial_packages: [py-scipy]
specs:
- gcc@12%gcc@11
- matrix:
- [$mpi_packages]
- [$^mpis]
- [$^lapacks]
- [$%compilers]
- matrix:
- [$serial_packages]
- [$^lapacks]
- [$%compilers]
exclude:
- "py-scipy ^netlib-lapack"
view: false
concretizer:
unify: false
Different definitions of lists with the same name are concatenated, so we can define our MPI list in one place unconditionally, and then conditionally append one or more values to it.
First, check what happens when we concretize and don’t set any environment variable:
$ spack concretize
==> No new specs to concretize.
$ spack find -cl netlib-scalapack
==> In environment /home/spack/stacks
==> 4 root specs
-- no arch / no compilers ---------------------------------------
[+] fmxnit5 gcc@12 [+] tl5f6ke netlib-scalapack
[+] igwbxq4 netlib-scalapack [+] qbiffx7 py-scipy
-- linux-ubuntu22.04-x86_64_v3 / %c,fortran=gcc@12.5.0 ----------
[+] igwbxq4 netlib-scalapack@2.2.2 [+] tl5f6ke netlib-scalapack@2.2.2
==> 2 installed packages
==> 0 concretized packages to be installed
As we expected we are only using mpich as an MPI provider.
To get openmpi back we need to set the appropriate environment variable:
$ export SPACK_STACK_USE_OPENMPI=1
$ spack concretize
$ spack find -cl netlib-scalapack
==> In environment /home/spack/stacks
==> 6 root specs
-- no arch / no compilers ---------------------------------------
[+] fmxnit5 gcc@12 [+] tl5f6ke netlib-scalapack [+] nimjflq netlib-scalapack
[+] igwbxq4 netlib-scalapack [+] hk7ftpc netlib-scalapack [+] qbiffx7 py-scipy
-- linux-ubuntu22.04-x86_64_v3 / %c,fortran=gcc@12.5.0 ----------
[+] igwbxq4 netlib-scalapack@2.2.2 [+] hk7ftpc netlib-scalapack@2.2.2
[+] tl5f6ke netlib-scalapack@2.2.2 [+] nimjflq netlib-scalapack@2.2.2
==> 4 installed packages
==> 0 concretized packages to be installed
There is no need to install this time, since all the specs were still in the store.
Other useful features¶
Sometimes it might be useful to create a local source mirror for the specs installed in an environment. If the environment is active, this is as simple as:
$ spack mirror create --all -d ./stacks-mirror
This command fetches all the tarballs for the packages in the spack.lock file, and puts them in the directory passed as argument.
Later you can move this mirror to e.g. an air-gapped machine and:
$ spack mirror add <name> <stacks-mirror>
to be able to re-build the specs from sources. Alternatively, to create a buildcache you can:
$ spack gpg create <name> <e-mail>
$ spack buildcache push ./mirror
Don’t forget to set an appropriate value for the padding of the install tree, see how to setup relocation in our documentation.
By default, Spack installs one package at a time, using the -j option where it can.
The spack install command has an optional -p option for the number of packages to build in parallel.
Note that each parallel package may consume the number of threads of the -j option.
You can use node resources more optimally by creating a depfile, when the environment is active:
$ spack env depfile -o Makefile
The result is a makefile that starts multiple Spack instances, and the resources are shared through the GNU jobserver. More information of this feature can be found in our documentation. This might cut down your build time by a fair amount, if you build frequently from sources. Expect this feature to be streamlined in future versions of Spack.
Make the software stack easy to use¶
Now that the software stack has been installed, we need to focus on how it can be used by our customers. We’ll first see how we can configure views to project a subset of the specs we installed onto a filesystem folder with the usual Unix structure. Then we’ll have a similar discussion for module files. Which of the two approaches is better depends strongly on the use case at hand.
View descriptors¶
At the beginning, we configured Spack not to create a view for this stack because simple views won’t work with stacks. We’ve been concretizing multiple packages of the same name, and they would conflict if linked into the same view.
What we can do is create multiple views, using view descriptors.
This would allows us to define which packages are linked into the view, and how.
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.
spack:
definitions:
- mpis: [mpich]
- mpis: [openmpi]
when: 'env.get("SPACK_STACK_USE_OPENMPI", "") == "1"'
- lapacks: [ openblas, netlib-lapack ]
- compilers: [ "gcc@12" ]
- mpi_packages: [ netlib-scalapack ]
- serial_packages: [py-scipy]
specs:
- gcc@12%gcc@11
- matrix:
- [$mpi_packages]
- [$^mpis]
- [$^lapacks]
- [$%compilers]
- matrix:
- [$serial_packages]
- [$^lapacks]
- [$%compilers]
exclude:
- "py-scipy ^netlib-lapack"
concretizer:
unify: false
view:
default:
root: views/default
select: ['%gcc@12']
exclude: [^mpich, ^netlib-lapack]
full:
root: views/full
projections:
^mpi^lapack: '{name}/{name}-{version}-{^c.name}-{^c.version}-{^mpi.name}-{^mpi.version}-{^lapack.name}-{^lapack.version}'
^lapack: '{name}/{name}-{version}-{^c.name}-{^c.version}-{^lapack.name}-{^lapack.version}'
'%c': '{name}/{name}-{version}-{^c.name}-{^c.version}'
'%cxx': '{name}/{name}-{version}-{^cxx.name}-{^cxx.version}'
'%fortran': '{name}/{name}-{version}-{^fortran.name}-{^fortran.version}'
all: '{name}/{name}-{version}'
In the configuration above we created two views, named default and full.
The default view consists of all the packages that are compiled with gcc@12, but do not depend on either mpich or netlib-lapack.
As we can see, we can both include and exclude specs using constraints.
The full view contains a more complex projection, so to put each spec into an appropriate subdirectory, according to the first constraint that the spec matches. all is the default projection, and has always the lowest priority, independent of the order in which it appears.
To avoid confusion, we advise always keeping it last in projections.
Concretize to regenerate the views, and check their structure:

Now we see only the root libraries in the default view. The rest are hidden, but are still available in the full view. The complete documentation on views can be found here.
Module files¶
Module files are another very popular way to use software on HPC systems.
In this section we’ll show how to configure and generate a hierarchical module structure, suitable for lmod.
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
$ 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 have the module command available in your shell:
$ module --version
Modules based on Lua: Version 8.7.18 2023-01-14 07:33 -06:00
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.
spack:
definitions:
- mpis: [mpich]
- mpis: [openmpi]
when: 'env.get("SPACK_STACK_USE_OPENMPI", "") == "1"'
- lapacks: [ openblas, netlib-lapack ]
- compilers: [ "gcc@12" ]
- mpi_packages: [ netlib-scalapack ]
- serial_packages: [py-scipy]
specs:
- gcc@12%gcc@11
- matrix:
- [$mpi_packages]
- [$^mpis]
- [$^lapacks]
- [$%compilers]
- matrix:
- [$serial_packages]
- [$^lapacks]
- [$%compilers]
exclude:
- "py-scipy ^netlib-lapack"
view: false
concretizer:
unify: false
modules:
default:
enable:
- lmod
roots:
lmod: modules
lmod:
hierarchy:
- mpi
- lapack
core_specs:
- '%gcc@11'
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’ve also configured it to place all specs built with our system compiler into the Core designation in the lmod hierarchy.
We can generate the module files and use them with the following commands:
$ spack module lmod refresh -y
$ module use $PWD/stacks/modules/linux-ubuntu22.04-x86_64/Core
Now we should be able to see the module files that have been generated:
$ module av

D: Default Module
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 set 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 of modules available - all the ones compiled with gcc@12:
$ module load gcc
$ which gcc
/home/spack/spack/opt/spack/linux-x86_64_v3/gcc-12.5.0-fmxnit5ggu45byub6wlsuienth2dkboh/bin/gcc
$ gcc --version
gcc (Spack GCC) 12.5.0

$ module unload gcc
There are a few issues though.
For instance, 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 prevent users from 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 are not part of the hash - for instance a policy at the deploying site.
To address all these needs we can complicate our 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]
when: 'env.get("SPACK_STACK_USE_OPENMPI", "") == "1"'
- lapacks: [ openblas, netlib-lapack ]
- compilers: [ "gcc@12" ]
- mpi_packages: [ netlib-scalapack ]
- serial_packages: [py-scipy]
specs:
- gcc@12%gcc@11
- matrix:
- [$mpi_packages]
- [$^mpis]
- [$^lapacks]
- [$%compilers]
- matrix:
- [$serial_packages]
- [$^lapacks]
- [$%compilers]
exclude:
- "py-scipy ^netlib-lapack"
view: false
concretizer:
unify: false
modules:
default:
enable:
- lmod
roots:
lmod: modules
lmod:
hierarchy:
- mpi
- lapack
core_specs:
- '%gcc@11'
hash_length: 0
include:
- gcc
exclude:
- '%gcc@11.4.0'
all:
environment:
set:
'{name}_ROOT': '{prefix}'
openmpi:
environment:
set:
SLURM_MPI_TYPE: pmi2
OMPI_MCA_btl_openib_warn_default_gid_prefix: '0'
projections:
all: '{name}/{version}'
Regenerate the modules 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

This concludes the quick tour of module file generation, and the tutorial on stacks.
Summary¶
In this tutorial, we configured Spack to install a stack of software built on a cross-product of different MPI and LAPACK libraries. We used the spec matrix syntax to express in a compact way the specs to be installed, and spec list definitions to reuse the same matrix rows in different places. Then, we discussed how to make the software easy to use, leveraging either filesystem views or module files.
