This is a training tutorial to lean how to use the cluster Meso@LR.
* [Meso@LR](https://meso-lr.umontpellier.fr/) - Landing page for getting started with Meso@LR cluster.
* [CheatSheet Slurm](https://nextcloud.inrae.fr/s/qs97RCJGF5tkMeK) - TLDR for slurm commands.
* [Meso@LR user documentation](https://meso-lr.umontpellier.fr/documentation-utilisateurs/) - Documentation made by the admins of Meso@LR
* [Meso@LR admin mail](mailto:meso-tech-calcul@umontpellier.fr) - Where to ask if you need help.
* [CNRS HPC related mailing-list](https://calcul.math.cnrs.fr/) - Where to ask if you need MORE help. Big mailing list of developpers, engineers and everything centered about HPC.
## How to open an acount on Meso@LR
Return both forms filled and signed to [Meso@LR Mail](mailto:isdm-calcul@umontpellier.fr)
1. [Application form](https://meso-lr.umontpellier.fr/wp-content/uploads/2021/03/1-Meso_dde_Calcul_nomprojets.doc)
2. [IT Charter](https://meso-lr.umontpellier.fr/wp-content/uploads/2021/03/20210319-MESO-CALCUL-CharteInformatique.pdf)
You should first clone the repository when you login to Meso@LR by executing this command =>
```bash
git clone https://forgemia.inra.fr/formationcalcul2022/formation-slurm.git
```
Cloning the repo will just copy all the contents you see on your screen to folders on Meso@LR. If you don't know how to connect to Meso@LR, please do [Exercise 1](./Exercise1-Connect_to_MesoLR) first.
Multiple folders are available each one containing a different exercice. You can do all of them or you can pick the ones you think you need the most.
**IMPORTANT**: *You should run your jobs out of the folder named "scratch" on your account (which is a link to /lustre/$USER). The filesystem is a very fast one and provide vast amounts of storage. Do not run jobs out of your home, mainly because it won't work (when running a job on the cluster, everything expect "scratch" is mounted as read-only). These filesystems are slow and should only be used for backing-up the files that you produce on "scratch". Your /home directory on the cluster should only be used for storing source code, executables, Conda environments, singularity images and small data sets*.
``` bash
jobs # A job is a program launched via SLURM.
nodes # A compute server
login-nodes # A server used to login on Meso@LR
```
