Basic Installation Tutorial¶
This tutorial will guide you through the process of installing
software using Spack. We will first cover the spack install
command,
focusing on the power of the spec syntax and the flexibility it gives
to users. We will also cover the spack find
command for viewing
installed packages and the spack uninstall
command for uninstalling
them. Finally, we will touch on how Spack manages compilers,
especially as it relates to using Spack-built compilers within Spack.
We will include full output from all of the commands demonstrated,
although we will frequently call attention to only small portions of
that output (or merely to the fact that it succeeded). The provided
output is all from an AWS instance running Ubuntu 18.04.
Installing Spack¶
Spack works out of the box. Simply clone Spack to get going. We will clone Spack and immediately check out the most recent release, v0.18.
$ git clone -c feature.manyFiles=true https://github.com/spack/spack.git ~/spack
Cloning into '/home/spack/spack'...

$ cd ~/spack
$ git checkout releases/v0.18
Branch 'releases/v0.18' set up to track remote branch 'releases/v0.18' from 'origin'.
Switched to a new branch 'releases/v0.18'
Next, add Spack to your path. Spack has some nice command-line
integration tools, so instead of simply appending to your PATH
variable, source the Spack setup script.
$ . share/spack/setup-env.sh
You’re good to go!
What is in Spack?¶
The spack list
command shows available packages.
$ spack list
==> 6416 packages.
3dtk ip2 podman py-pygtrie r-packrat
3proxy ipcalc poke py-pyh5md r-pacman
abacus iperf2 polymake py-pyheadtail r-paleotree
abduco iperf3 poplddecay py-pyinstrument r-pamr
The spack list
command can also take a query string. Spack
automatically adds wildcards to both ends of the string, or you
can add your own wildcards. For example, we can view all available
Python packages.
$ spack list 'py-*'
==> 1821 packages.
py-3to2 py-cinema-lib py-google-auth py-msgpack-numpy py-pyke py-sierrapy
py-4suite-xml py-cinemasci py-google-auth-httplib2 py-msrest py-pykml py-simplegeneric

py-abipy py-clean-text py-google-cloud-core py-multi-key-dict py-pykwalify py-simplekml
Installing Packages¶
Installing a package with Spack is very simple. To install a piece of
software, simply type spack install <package_name>
.

Spack can install software either from source or from a binary cache. Packages in the binary cache are signed with GPG for security. For the tutorial we have prepared a binary cache so you don’t have to wait on slow compilation from source. To be able to install from the binary cache, we will need to configure Spack with the location of the binary cache and trust the GPG key that the binary cache was signed with.
$ spack mirror add tutorial /mirror
$ spack buildcache keys --install --trust
gpg: key A8E0CA3C1C2ADA2F: 7 signatures not checked due to missing keys
gpg: key A8E0CA3C1C2ADA2F: public key "Spack Project Official Binaries <maintainers@spack.io>" imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: no ultimately trusted keys found
gpg: inserting ownertrust of 6
You’ll learn more about configuring Spack later in the tutorial, but
for now you will be able to install the rest of the packages in the
tutorial from a binary cache using the same spack install
command. By default this will install the binary cached version if it
exists and fall back on installing from source if it does not.
Spack’s spec syntax is the interface by which we can request specific
configurations of the package. The %
sigil is used to specify
compilers.

Note that this installation is located separately from the previous one. We will discuss this in more detail later, but this is part of what allows Spack to support arbitrarily versioned software.
You can check for particular versions before requesting them. We will
use the spack versions
command to see the available versions, and then
install a different version of zlib
.

The spec syntax also includes compiler flags. Spack accepts
cppflags
, cflags
, cxxflags
, fflags
, ldflags
, and
ldlibs
parameters. The values of these fields must be quoted on
the command line if they include spaces. These values are injected
into the compile line automatically by the Spack compiler wrappers.

The spack find
command is used to query installed packages. Note that
some packages appear identical with the default output. The -l
flag
shows the hash of each package, and the -f
flag shows any non-empty
compiler flags of those packages.

Spack generates a hash for each spec. This hash is a function of the full provenance of the package, so any change to the spec affects the hash. Spack uses this value to compare specs and to generate unique installation directories for every combinatorial version. As we move into more complicated packages with software dependencies, we can see that Spack reuses existing packages to satisfy a dependency. By default, Spack tries hard to reuse existing installations as dependencies, either from a local store or from configured remote buildcaches. This minimizes unwanted rebuilds of common dependencies, in particular if you update Spack frequently.

Dependencies can be explicitly requested using the ^
sigil. Note that
the spec syntax is recursive. Anything we could specify about the
top-level package, we can also specify about a dependency using ^
.

Packages can also be referred to from the command line by their package
hash. Using the spack find -lf
command earlier we saw that the hash
of our optimized installation of zlib (cppflags="-O3"
) began with
2f2
. We can now explicitly build with that package without typing
the entire spec, by using the /
sigil to refer to it by hash. As with
other tools like Git, you do not need to specify an entire hash on the
command line. You can specify just enough digits to identify a hash
uniquely. If a hash prefix is ambiguous (i.e., two or more installed
packages share the prefix) then Spack will report an error.

Spack packages can also have build options, called variants. Boolean
variants can be specified using the +
(enable) and ~
or -
(disable) sigils. There are two sigils for “disable” to avoid conflicts
with shell parsing in different situations. Variants (boolean or
otherwise) can also be specified using the same syntax as compiler flags.
Here we can install HDF5 without MPI support.

We might also want to install HDF5 with a different MPI
implementation. While MPI is not a package itself, packages can depend on
abstract interfaces like MPI. Spack handles these through “virtual
dependencies.” A package, such as HDF5, can depend on the MPI
interface. Other packages (openmpi
, mpich
, mvapich2
, etc.)
provide the MPI interface. Any of these providers can be requested for
an MPI dependency. For example, we can build HDF5 with MPI support
provided by MPICH by specifying a dependency on mpich
. Spack also
supports versioning of virtual dependencies. A package can depend on the
MPI interface at version 3, and provider packages specify what version of
the interface they provide. The partial spec ^mpi@3
can be satisfied
by any of several providers.

Spack models the dependencies of packages as a directed acyclic graph
(DAG). The spack find -d
command shows the tree representation of
that graph. We can also use the spack graph
command to view the entire
DAG as a graph.

You may also have noticed that there are some packages shown in the
spack find -d
output that we didn’t install explicitly. These are
dependencies that were installed implicitly. A few packages installed
implicitly are not shown as dependencies in the spack find -d
output. These are build dependencies. For example, hdf5
requires
cmake
to build. Spack will build cmake
as part of the
installation of hdf5
, but it does not become a part of the DAG
because it is not linked in at run time. Spack handles build
dependencies differently because of their different (less strict)
consistency requirements. It is entirely possible to have two packages
using different versions of a dependency to build, which obviously cannot
be done with linked dependencies.
HDF5 is more complicated than our basic example of zlib and Tcl, but it’s still within the realm of software that an experienced HPC user could reasonably expect to manually install given a bit of time. Now let’s look at an even more complicated package.
$ spack install trilinos

Now we’re starting to see the power of Spack. Trilinos in its default configuration has 23 top level dependencies, many of which have dependencies of their own. Installing more complex packages can take days or weeks even for an experienced user. Although we’ve done a binary installation for the tutorial, a source installation of Trilinos using Spack takes about 3 hours (depending on the system), but only 20 seconds of programmer time.
Spack manages consistency of the entire DAG. Every MPI dependency will be satisfied by the same configuration of MPI, etc. If we install Trilinos again specifying a dependency on our previous HDF5 built with MPICH:
$ spack install trilinos +hdf5 ^hdf5+hl+mpi ^mpich

As we discussed before, the spack find -d
command shows the
dependency information as a tree. While that is often sufficient, many
complicated packages, including Trilinos, have dependencies that
cannot be fully represented as a tree. Again, the spack graph
command shows the full DAG of the dependency information.

You can control how the output is displayed with a number of options.
The ASCII output from spack graph
can be difficult to parse for
complicated packages. The output can be changed to the Graphviz
.dot
format using the --dot
flag.
$ spack graph --dot trilinos | dot -Tpdf > trilinos_graph.pdf
Uninstalling Packages¶
Earlier we installed many configurations each of zlib and Tcl. Now we will go through and uninstall some of those packages that we didn’t really need.
$ spack find -d tcl
==> 3 installed packages
-- linux-ubuntu18.04-x86_64 / clang@7.0.0 -----------------------
tcl@8.6.12
zlib@1.2.8
-- linux-ubuntu18.04-x86_64 / gcc@7.5.0 -------------------------
tcl@8.6.12
zlib@1.2.8
tcl@8.6.12
zlib@1.2.12
$ spack find zlib
==> 6 installed packages
-- linux-ubuntu18.04-x86_64 / clang@7.0.0 -----------------------

-- linux-ubuntu18.04-x86_64 / gcc@7.5.0 -------------------------
zlib@1.2.8 zlib@1.2.8 zlib@1.2.12
We can uninstall packages by spec using the same syntax as install.
$ spack uninstall zlib %gcc@6.5.0
==> The following packages will be uninstalled:
-- linux-ubuntu18.04-x86_64 / gcc@6.5.0 -------------------------
g4z6hjr zlib@1.2.12
==> Do you want to proceed? [y/N] y
==> Successfully uninstalled zlib@1.2.12%gcc@6.5.0+optimize+pic+shared patches=0d38234 arch=linux-ubuntu18.04-x86_64/g4z6hjr
$ spack find -lf zlib
==> 5 installed packages
-- linux-ubuntu18.04-x86_64 / clang@7.0.0 -----------------------
3en3ddq zlib@1.2.8%clang 3svypja zlib@1.2.12%clang

gueun6g zlib@1.2.8%gcc 2f23wbx zlib@1.2.8%gcc cppflags="-O3" fntvsj6 zlib@1.2.12%gcc
We can also uninstall packages by referring only to their hash.
We can use either -f
(force) or -R
(remove dependents as well) to
remove packages that are required by another installed package.
$ spack uninstall zlib/3en
==> Will not uninstall zlib@1.2.8%clang@7.0.0/3en3ddq
The following packages depend on it:
-- linux-ubuntu18.04-x86_64 / clang@7.0.0 -----------------------
zeszs45 tcl@8.6.12
==> Error: There are still dependents.
use `spack uninstall --dependents` to remove dependents too
$ spack uninstall -R zlib/3en
==> The following packages will be uninstalled:
-- linux-ubuntu18.04-x86_64 / clang@7.0.0 -----------------------
zeszs45 tcl@8.6.12
3en3ddq zlib@1.2.8
==> Do you want to proceed? [y/N] y
==> Successfully uninstalled tcl@8.6.12%clang@7.0.0 arch=linux-ubuntu18.04-x86_64/zeszs45
==> Successfully uninstalled zlib@1.2.8%clang@7.0.0+optimize+pic+shared arch=linux-ubuntu18.04-x86_64/3en3ddq
Spack will not uninstall packages that are not sufficiently
specified. The -a
(all) flag can be used to uninstall multiple
packages at once.
$ spack uninstall trilinos
==> Error: trilinos matches multiple packages:
-- linux-ubuntu18.04-x86_64 / gcc@7.5.0 -------------------------
6t2acz7 trilinos@13.0.1 nk6x6g4 trilinos@13.0.1
==> Error: You can either:
a) use a more specific spec, or
b) specify the spec by its hash (e.g. `spack uninstall /hash`), or
c) use `spack uninstall --all` to uninstall ALL matching specs.
$ spack uninstall /6t2
==> The following packages will be uninstalled:

Advanced spack find
Usage¶
We will go over some additional uses for the spack find
command not
already covered in the Installing Spack and
Uninstalling Packages sections.
The spack find
command can accept what we call “anonymous specs.”
These are expressions in spec syntax that do not contain a package
name. For example, spack find ^mpich
will return every installed
package that depends on MPICH, and spack find cppflags="-O3"
will
return every package which was built with cppflags="-O3"
.
$ spack find ^mpich
==> 2 installed packages
-- linux-ubuntu18.04-x86_64 / gcc@7.5.0 -------------------------
hdf5@1.12.2 trilinos@13.0.1
$ spack find cppflags=-O3
==> 1 installed package
-- linux-ubuntu18.04-x86_64 / gcc@7.5.0 -------------------------
zlib@1.2.8
The find
command can also show which packages were installed
explicitly (rather than pulled in as a dependency) using the -x
flag. The -X
flag shows implicit installs only. The find
command can
also show the path to which a Spack package was installed using the -p
flag.
$ spack find -px
==> 10 installed packages

Customizing Compilers¶
Spack manages a list of available compilers on the system, detected
automatically from from the user’s PATH
variable. The spack
compilers
command is an alias for the command spack compiler list
.
$ spack compilers
==> Available compilers
-- clang ubuntu18.04-x86_64 -------------------------------------
clang@7.0.0
-- gcc ubuntu18.04-x86_64 ---------------------------------------
gcc@7.5.0 gcc@6.5.0
The compilers are maintained in a YAML file. Later in the tutorial you will learn how to configure compilers by hand for special cases. Spack also has tools to add compilers, and compilers built with Spack can be added to the configuration.
$ spack install gcc@8.4.0

We can add GCC to Spack as an available compiler using the spack
compiler add
command. This will allow future packages to build with
gcc@8.4.0
. To avoid having to copy and paste GCC’s path, we can use
spack location -i
to get the installation prefix.
$ spack compiler add $(spack location -i gcc@8.4.0)
==> Added 1 new compiler to /home/spack/.spack/linux/compilers.yaml
gcc@8.4.0
==> Compilers are defined in the following files:
/home/spack/.spack/linux/compilers.yaml
We can also remove compilers from our configuration using spack compiler remove <compiler_spec>
$ spack compiler remove gcc@8.4.0
==> Removed compiler gcc@8.4.0
