# Jean-Zay cheatsheet Jean Zay is the name of the new supercomputer converged platform acquired by the "French Ministry of Higher Education, Research and Innovation" through the intermediary of the French civil company, GENCI (Grand Equipement National De Calcul Intensif). Researchers, especially in AI, need powerful hardware to perform computational work, and they can access Jean Zay after following the required administrative procedures. ## Useful references - Connecting to Jean Zay from home ``` ssh authorized-machine ssh [email protected] ``` - [Check storage usage](http://www.idris.fr/jean-zay/cpu/jean-zay-cpu-calculateurs-disques.html): ``` idr_quota_user ``` - [Check computing hours accounting](http://www.idris.fr/jean-zay/cpu/jean-zay-cpu-doc_account.html): ``` idracct ``` - Loading a PyTorch environment ``` module load pytorch-gpu/py3/1.13.0 ``` - [Launch a slurm job](http://www.idris.fr/jean-zay/gpu/jean-zay-gpu-exec_mono_batch.html) ``` sbatch job.slurm ``` This puts your job in a queue and you can check its status with ``` squeue -u $USER ``` Once it's done, the output will be written to the output file. --- ## 📚 References - The official Jean Zay website <http://www.idris.fr/jean-zay/> - A community-made documentation <https://jean-zay-doc.readthedocs.io/en/latest/>
