lapack

Comment utiliser la librairie lapack sous l'environnement nvhpc ? Voici un exemple script.slurm (BigInt=32, BigInt=64)

#!/bin/bash
#SBATCH -J script_art63
#SBATCH -N 1
#SBATCH -n 1
#SBATCH -c 80
#SBATCH --time=00:40:00
#SBATCH -w turpancomp1

#reprsentation digitale des entiers : 32 ou 64 bits
