You need to install the UTM virtual machine manager In your browser, go to mac.getutm.app, and click on the Download button.
Mount the downloaded UTM.dmg disk-image and drag the UTM app to the Applications folder. Next, launch the UTM app from your Mac’s local Applications folder. (Depending on your Mac’s security settings, you may get a confirmation dialog when you launch UTM for the first time. If such a dialog appears, choose Open.)
Install a linux distribution compatible to the M2 machine: ARM
You can find rockylinux iso image at this address: https://rockylinux.org/download.
Or use Ubuntu Server for ARM available here: https://ubuntu.com/download/server/arm
(des informatiojn complementaire sont disponible ici https://guix.gnu.org/fr/manual/devel/fr/html_node/Installation-binaire.html)
Open terminal and become root:
sudo su -
download and install guix:
wget https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh
chmod +x guix-install.sh
./guix-install.sh
You can check where guix has been installed
type -P guix
At this point the guix daemon can be not yet working
guix pull
guix pull: erreur : impossible de se connecter à « /var/guix/daemon-socket/socket » : Connexion refusée
Running with systmclt did not work neither
systemctl start guix-daemon.service
So we visualise the service system
cat /etc/systemd/system/guix-daemon.service
and manually execute what is present in the ExecStart paragraph:
/var/guix/profiles/per-user/root/current-guix/bin/guix-daemon --build-users-group=guixbuild --discover=yes
Then it works and you can test that everything is working fine;
guix shell hello -- hello
Todo: Find a way to make the daemon working smoothly

Install a tool
guix install nano
If you call nano it might not work out of the box you would need to set the env properly doing.
GUIX_PROFILE="/home/jdainat/.guix-profile"
. "$GUIX_PROFILE/etc/profile"
Then you can call the tool. To see where the tool is install you can do
type -P nano
readlink -f $(type -P emacs)
guix package --list-installed # list what is installed
guix package --list-generations # list all generation. A generation is a layer of installation...
guix package --rollback # to go back to a rpevious generation
doing
guix shell gcc-toolchain openmpi
will create a subshell with gcc and openmpi installed in it. ([env])
To quit this env run exit.
The env is still leaving aroud. No need to think about disk usage (space is made automatically when needed by the computer using garbage collector) but if needed, run the following command:
guix gc # garbage collector to clean what is no longerneeded.
To not extend an existing shell it is possible to run a command to run programm in a container using -C and --container is the same
e.g.:
guix -C gcc-toolchain openmpi
This time only gcc and openmpi is avialable even ls command does not exist anymore. To use ls or grep we need to add coreutils among the packages to install in the env.
The container option is not only doing a env for the tool but also load only the working directory as an isolated container.
ls / you do not see the /userit re-recreate a full clean working env.
To load specific file or direcotry in the container use --expose=...path... this will be read/write. Another option exists to access read only.
/!\ Do not never mix package from guix / module / spack. It is why it is important when using guix to use it with container option.
So package should be fully guixor spack or module.
-C is not usable on a HPC because rely to something not avaiblable. Instead you need to use --pure? instead.
When you need lot of packages it becomes important to use manifiest files.
guix shell python python-numpy python-scipy --export-manifest > manifest.scm
To use an existing manifest
guix shell -m manifesst.scm
By adding new channels e.g. guix-hpc guix-sci
There is only one version of each tool at every guix version. Top keep track of the exact version:
guix describe -f channels > channels.scm
For reproducibility we need the channels.scm and manifest.scm
