Chapter 3.2 : The job script

1

#!/bin/bash


Commençons par le prefix de notre programme (si on considère que nous lancerons nos jobs depuis les sources) : 
1

PREFIX=${PWD}


On affiche sur quelle machine on tourne : 
1

echo "Used machine is $(uname -a)"


On définit un dossier build unique pour que plusieurs jobs ne se marchent pas dessus : 
1
2
3
4
5
6
7

BUILD_DIR="${PREFIX}/build_cmake_$(uname -n)"

if [ -d ${BUILD_DIR} ]
then
    	echo "Remove existing directory $BUILD_DIR"
        rm -fr ${BUILD_DIR}
fi


Créons notre dossier de compilation : 
1
2

mkdir -p ${BUILD_DIR}
echo "BUILD_DIR = '${BUILD_DIR}'"


Définition notre image Apptainer : 
1

CONTAINER_IMAGE="./introduction_cpp_algorithms_alpine_light_latest.sif"


On appelle le script d'installation que nous définirons dans la section secApptainerInstallSingularity : 
1

apptainer run --bind $PREFIX:/source --bind ${BUILD_DIR}:/build ${CONTAINER_IMAGE} /source/compile_example.sh
