 # ICON
 ICON (Icosahedral Nonhydrostatic Weather and Climate Model) is a global model suitable for climate and weather prediction at regional and global domains.
 It is a joint project of [DWD :material-open-in-new:](https://www.dwd.de/DE/Home/home_node.html){:target="_blank"}, [MPI-M :material-open-in-new:](https://mpimet.mpg.de/startseite){:target="_blank"} and [KIT :material-open-in-new:](https://www.kit.edu/){:target="_blank"}.

+### Temporary Tödi
+
+!!! warning "These are only temporary guidelines during the acceptance phase of Alps"
+
+    - Santis will be the official W&C vcluster but Tödi has to be deployed on the entire Alps system for the acceptance phase. These guidelines are for the ones who have access to Tödi.
+    - The resulting executable is not tested.
+    - Anything can go wrong
+
+- Install latest `uenv` tool
+    ```shell
+    git clone [email protected]:eth-cscs/uenv.git && ./uenv/install --local
+    ```
+
+- Get `spack-c2sm` on the `uenv_ci` branch
+    ```shell
+    git clone --depth 1 --recurse-submodules --shallow-submodules -b uenv_ci https://github.com/C2SM/spack-c2sm.git
+    ```
+
+- Start user environment
+    ```shell
+    uenv start /capstor/scratch/cscs/leclairm/uenvs/images/icon_c2sm_v1_rc3.sqfs
+    ```
+
+- Setup `spack-c2sm`
+    ```shell
+    source spack-c2sm/setup-env.sh /user-environment
+    ```
+
+- Adapt your spack environment following `/capstor/scratch/cscs/leclairm/icon-nwp/config/cscs/spack/uenv/mch_gpu_double/spack.yaml`  and activate it as usual with `spack env activate`.
+
+- Build as usual from your icon root dir
+    ```shell
+    spack install
+    ```
+
+- Submit job with uenv
+    ```shell
+    sbatch --uenv /capstor/scratch/cscs/leclairm/uenvs/images/icon_c2sm_v1_rc3.sqfs my_run_script
+    ```
+
 ## Run test case with ICON
 In the *run* folder, you find many prepared test cases, which you can convert into run scripts. To generate the runscript of one of the experiment files, e.g. *mch_ch_lowres*, you can use the `make_runscripts` function.
