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
BigInt=64

module purge
module load nvhpc-nompi/22.9 
export BINARY=test_LU_f
export SOURCE=test_LU

rm -f ${SOURCE}.o ${BINARY}
if [ ${BigInt} -eq 64 ]
then
echo "compilation integer 64 bit"
nvfortran -c -DBIGINT -O3 -g -cpp -Minfo -mp=multicore ${SOURCE}.F90
