+Welcome to the jungle, a set of machines with no imposed rules that are fully
+controlled and maintained by their users.
+
+The configuration of all the machines is written in a centralized [git
+repository][config] using the Nix language for NixOS. Changes in the
+configuration of the machines are introduced by merge requests and pass a review
+step before being deployed.
+
+[config]: https://pm.bsc.es/gitlab/rarias/jungle
+
+The machines have access to the large list of packages available in
+[Nixpkgs][nixpkgs] and a custom set of packages named [bscpkgs][bscpkgs],
+specifically tailored to our needs for HPC machines. Users can install their own
+packages and made them system-wide available by opening a merge request.
+
+[nixpkgs]: https://github.com/NixOS/nixpkgs
+[bscpkgs]: https://pm.bsc.es/gitlab/rarias/bscpkgs
+
+We have put a lot of effort to guarantee very good reproducibility properties in
+the configuration of the machines and the software they use.
+
+To enter the jungle machines follow the [instructions](access) to submit a
+request.

+1. Your user name (make sure it matches the one you use for the BSC intranet)
+1. Your real name and surname (for identification purposes)

+title: "Quick start"

+
+This documentation will guide you on how to build custom packages of software
+and use them in the jungle machines. It has been designed to reduce the friction
+from users coming from module systems.
+
+You should be able to access the jungle machines, otherwise [request
+access](/access).
+
+## Changes from other HPC machines
+
+Users of other machines have been using the Lmod tool (module load ...) to add
+or remove programs from their environment, as well as manually building their
+own software for too many years.
+
+While we cannot prevent users from continuing to use this tedious mechanism, we
+have designed the jungle machines to be much easier to operate by using the nix
+package manager.
+
+### Freedom to install packages
+
+When a user wanted to install a package, it was forced to either do it on its
+own directory, or request a system administrator to install it in a shared
+directory, so other users can also use that package.
+
+This situation is gone, each user can install any package of software by
+themselves, without requiring any other authorization. When two users request
+the same package, the same copy will be provided.
+
+A new package will be downloaded if it is available (someone already built it)
+or will be built from source on demand.
+
+### No changes over time
+
+All users retain the same versions of the packages they request until they
+decide to update them.
+
+## Using nix to manage packages
+
+In this chapter we show how to install packages and enter a development shell to
+build new programs from source. The examples are done from the hut machine,
+read [this page](/access) to request access.
+
+### Installing binaries
+
+To temporarily install new packages, use:
+
+```text
+hut% nix shell jungle#gcc jungle#cowsay jungle#ovni
+```
+
+Notice that the packages are described as two parts divided by the `#` symbol.
+The first part defines where to take the package from and the second part is
+the name of the package. For now we will use `jungle#<package>`. You can find
+many more packages here:
+
+<https://search.nixos.org/packages>
+
+You will now enter a new shell, where those requested package **binaries are
+available in $PATH**:
+
+```text
+hut% cowsay hello world
+ _____________
+< hello world >
+ -------------
+        \   ^__^
+         \  (oo)\_______
+            (__)\       )\/\
+                ||----w |
+                ||     ||
+
+hut% ovniver
+LD_LIBRARY_PATH not set
+libovni: build v1.11.0 (a7103f8), dynamic v1.11.0 (a7103f8)
+
+hut% gcc --version
+gcc (GCC) 13.3.0
+Copyright (C) 2023 Free Software Foundation, Inc.
+This is free software; see the source for copying conditions.  There is NO
+warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
+```
+
+### Building programs
+
+The above method only loads new binaries in the `$PATH`. If we try to build a
+program that includes headers or links with a library, it will fail to find
+them:
+
+```text
+hut$ cat test.c
+#include <ovni.h>
+
+int main()
+{
+        ovni_version_check();
+        return 0;
+}
+hut% gcc test.c -lovni -o test
+test.c:1:10: fatal error: ovni.h: No such file or directory
+    1 | #include <ovni.h>
+      |          ^~~~~~~~
+compilation terminated.
+```
+
+We could manually add the full path to the ovni include directory with `-I` and
+the libraries with `-L`, but there is a tool that already perform these steps
+automatically for us, `nix develop`.
+
+Let's go back to our original shell first, where those packages are not
+available anymore:
+
+```
+hut% ps
+    PID TTY          TIME CMD
+2356260 pts/1    00:00:01 zsh
+2457268 pts/1    00:00:00 zsh
+2457297 pts/1    00:00:00 ps
+hut% exit
+hut% ovniver
+ovniver: command not found
+```
+
+### Creating a flake.nix
+
+To define which packages we want, we will write a small file that list them, a
+flake.nix file.
+
+First, we will create a new directory where we are going to be working:
+
+```
+hut% mkdir example
+hut% cd exmple
+```
+
+Then place this flake.nix file:
+
+```nix
+{
+  inputs.jungle.url = "jungle";
+  outputs = { self, jungle }:  
+  let
+    pkgs = jungle.outputs.packages.x86_64-linux;
+  in {
+    devShells.x86_64-linux.default = pkgs.mkShell {
+      pname = "devshell";
+      buildInputs = with pkgs; [
+        ovni gcc cowsay # more packages here...
+      ];
+    };
+  };
+}
+```
+
+
+Now enter the shell with:
+

+
+Notice that long list of messages is Nix creating a new flake.lock file with the
+current state of the packages. Next invocations will use the same packages as
+described by the lock file.
+
+### Building a program from nix develop
+
+Now let's try again building our test program:
+
+```text
+hut$ cat test.c
+#include <ovni.h>
+
+int main()
+{
+        ovni_version_check();
+        return 0;
+}
+hut$ gcc test.c -o test -lovni
+hut$ ldd test
+        linux-vdso.so.1 (0x00007ffff7fc4000)
+        libovni.so.1 => /nix/store/sqk972akjv0q8dchn8ccjln2llzyyfd0-ovni-1.11.0/lib/libovni.so.1 (0x00007ffff7fab000)
+        libc.so.6 => /nix/store/nqb2ns2d1lahnd5ncwmn6k84qfd7vx2k-glibc-2.40-36/lib/libc.so.6 (0x00007ffff7db2000)
+        /nix/store/nqb2ns2d1lahnd5ncwmn6k84qfd7vx2k-glibc-2.40-36/lib/ld-linux-x86-64.so.2 => /nix/store/nqb2ns2d1lahnd5ncwmn6k84qfd7vx2k-glibc-2.40-36/lib64/ld-linux-x86-64.so.2 (0x00007ffff7fc6000)
+hut$ ./test
+```
+
+Now the ovni.h header and the libovni library are found and the program is
+successfully built, linked and executed.
+
+You can add more packages as needed in your flake.nix:
+
+```nix
+  buildInputs = with pkgs; [
+    ovni gcc cowsay # more packages here...
+  ];
+```
+
+Make sure you exit the develop shell first, and then enter again with `nix
+develop`.
+
+## Remember
+
+- `nix shell` places binaries in the `$PATH`.
+- `nix develop` enters a development shell where both binaries and the libraries
+  and includes are available so you can build new programs.

+[CC0](http://creativecommons.org/publicdomain/zero/1.0/deed.en).
+
+The *fox* machine is a big GPU server that is configured to run heavy workloads.
+It has two fast AMD CPUs with large cache and 2 reasonable NVIDIA GPUs. Here are
+the detailed specifications:
+
+- 2x AMD GENOA X 9684X DP/UP 96C/192T 2.55G 1,150M 400W SP5 3D V-cach
+- 24x 32GB DDR5-4800 ECC RDIMM (total 768 GiB of RAM)

+- 2x 2.5" KIOXIA CM7-R 1.92TB NVMe GEN5 PCIe 5x4
+- 2x NVIDIA RTX4000 ADA Gen 20GB GDDR6 PCIe 4.0
+
+## Access
+
+To access the machine, request a SLURM session from [hut](/hut) using the `fox`
+partition:
+
+    hut% salloc -p fox
+
+Then connect via ssh:
+
+    hut% ssh fox
+    fox%
+
+Follow [these steps](/access) if you don't have access to hut or fox.
+
+## CUDA
+
+To use CUDA, you can use the following `flake.nix` placed in a new directory to
+load all the required dependencies:
+
+```nix
+{
+  inputs.jungle.url = "jungle";
+
+  outputs = { jungle, ... }: {
+    devShell.x86_64-linux = let
+      pkgs = jungle.nixosConfigurations.fox.pkgs;
+    in pkgs.mkShell {
+      name = "cuda-env-shell";
+      buildInputs = with pkgs; [
+        git gitRepo gnupg autoconf curl
+        procps gnumake util-linux m4 gperf unzip
+
+        # Cuda packages (more at https://search.nixos.org/packages)
+        cudatoolkit linuxPackages.nvidia_x11
+        cudaPackages.cuda_cudart.static
+        cudaPackages.libcusparse
+
+        libGLU libGL
+        xorg.libXi xorg.libXmu freeglut
+        xorg.libXext xorg.libX11 xorg.libXv xorg.libXrandr zlib
+        ncurses5 stdenv.cc binutils
+      ];
+      shellHook = ''
+        export CUDA_PATH=${pkgs.cudatoolkit}
+        export LD_LIBRARY_PATH=/var/run/opengl-driver/lib
+        export SMS=50
+      '';
+    };
+  };
+}
+```
+
+Then just run `nix develop` from the same directory:
+
+    % mkdir cuda
+    % cd cuda
+    % vim flake.nix
+    [...]
+    % nix develop
+    $ nvcc -V
+    nvcc: NVIDIA (R) Cuda compiler driver
+    Copyright (c) 2005-2024 NVIDIA Corporation
+    Built on Tue_Feb_27_16:19:38_PST_2024
+    Cuda compilation tools, release 12.4, V12.4.99
+    Build cuda_12.4.r12.4/compiler.33961263_0
+
+## Filesystems
+
+The machine has several file systems available.
+
+- `$HOME`: Mounted via NFS across all nodes. It is slow and has low capacity.
+  Don't abuse.
+- `/ceph/home/$USER`: Shared Ceph file system across jungle nodes. Slow but high
+  capacity. Stores three redundant copies of every file.
+- `/nvme{0,1}/$USER`: The two local NVME disks, very fast and large capacity.
+- `/tmp`: tmpfs, fast but not backed by a disk. Will be erased on reboot.

+![Hut](hut.jpg)
+
+From the hut we monitor and control other nodes. It consist of one node only,
+which is available at `hut` or `xeon07`. It runs the following services:
+
+- Prometheus: to store the monitoring data.
+- Grafana: to plot the data in the web browser.
+- Slurmctld: to manage the SLURM nodes.
+- Gitlab runner: to run CI jobs from Gitlab.
+- Nix binary cache: to serve cached nix builds
+
+This node is prone to interruptions from all the services it runs, so it is not
+a good candidate for low noise executions.
+
+# Binary cache
+
+We provide a binary cache in `hut`, with the aim of avoiding unnecessary
+recompilation of packages.
+
+The cache should contain common packages from bscpkgs, but we don't provide
+any guarantee that of what will be available in the cache, or for how long.
+We recommend following the latest version of the `jungle` flake to avoid cache
+misses.
+
+## Usage
+
+### From NixOS
+
+In NixOS, we can add the cache through the `nix.settings` option, which will
+enable it for all builds in the system.
+
+```nix
+{ ... }: {
+  nix.settings = {
+    extra-substituters = [ "https://jungle.bsc.es/cache" ];
+    extra-trusted-public-keys = [ "jungle.bsc.es:pEc7MlAT0HEwLQYPtpkPLwRsGf80ZI26aj29zMw/HH0=" ];
+  };
+}
+```
+
+### Interactively
+
+The cache can also be specified in a per-command basis through the flags
+`--substituters` and `--trusted-public-keys`:
+
+```sh
+nix build --substituters "https://jungle.bsc.es/cache" --trusted-public-keys "jungle.bsc.es:pEc7MlAT0HEwLQYPtpkPLwRsGf80ZI26aj29zMw/HH0=" <...>
+```
+
+Note: you'll have to be a trusted user.
+
+### Nix configuration file (non-nixos)
+
+If using nix outside of NixOS, you'll have to update `/etc/nix/nix.conf`
+
+```
+# echo "extra-substituters = https://jungle.bsc.es/cache" >> /etc/nix/nix.conf
+# echo "extra-trusted-public-keys = jungle.bsc.es:pEc7MlAT0HEwLQYPtpkPLwRsGf80ZI26aj29zMw/HH0=" >> /etc/nix/nix.conf
+```
+
+### Hint in flakes
+
+By adding the configuration below to a `flake.nix`, when someone uses the flake,
+`nix` will interactively ask to trust and use the provided binary cache:
+
+```nix
+{
+  nixConfig = {
+    extra-substituters = [
+      "https://jungle.bsc.es/cache"
+    ];
+    extra-trusted-public-keys = [
+      "jungle.bsc.es:pEc7MlAT0HEwLQYPtpkPLwRsGf80ZI26aj29zMw/HH0="
+    ];
+  };
+  outputs = { ... }: {
+    ...
+  };
+}
+```
+
+### Querying the cache
+
+Check if the cache is available:
+```sh
+$ curl https://jungle.bsc.es/cache/nix-cache-info
+StoreDir: /nix/store
+WantMassQuery: 1
+Priority: 30
+```
+
+Prevent nix from building locally:
+```bash
+nix build --max-jobs 0 <...>
+```
+
+Check if a package is in cache:
+```bash
+# Do a raw eval on the <package>.outPath (this should not build the package)
+$ nix eval --raw jungle#openmp.outPath
+/nix/store/dwnn4dgm1m4184l4xbi0qfrprji9wjmi-openmp-2024.11
+# Take the hash (everything from / to - in the basename) and curl <hash>.narinfo
+# if it exists in the cache, it will return HTTP 200 and some information
+# if not, it will return 404
+$ curl https://jungle.bsc.es/cache/dwnn4dgm1m4184l4xbi0qfrprji9wjmi.narinfo

+
+Much like the silent flight of an owl at night, these nodes are configured to
+minimize the system noise and let programs run undisturbed. The list of nodes is
+`owl[1-2]` and are available for jobs with SLURM.
+
+The contents of the nix store of the hut node is made available in the owl nodes
+when a job is running. This allows jobs to access the same paths that are on hut
+to load dependencies.
+
+For now, only the hut node can be used to build new derivations so that they
+appear in the compute nodes. This applies to the `nix build`, `nix develop` and
+`nix shell` commands.
