Submissão de Jobs em Paralelo

Crie um arquivo chamado, por exemplo, submit_paral_jobs.sh.

#!/bin/bash
#SBATCH -t 24:00:00 -n 4

export INPUT="run.sh openfoam-airfoil.zip"
export OUTPUT="results.zip"

job-nanny ./run.sh

em que o script run.sh tem o seguinte conteúdo:

#!/bin/bash
module load openfoam/2012

unzip openfoam-airfoil.zip
decomposePar
mpirun -np 4 simpleFoam -parallel
reconstructPar
zip -r results.zip [0-9]*

Antes de submeter o job, deve-se tornar o script executável pelo comando

chmod +x run.sh

Para submeter o processo, basta usar o comando:

sbatch submit_paral_jobs.sh

Submissão de Jobs Seriais

Crie um arquivo chamado, por exemplo, submit_serial_jobs.sh.

#!/bin/bash
#SBATCH -t 24:00:00

export INPUT="run.sh openfoam-cavity.zip"
export OUTPUT="cavity.zip"

job-nanny ./run.sh

em que o script run.sh tem o seguinte conteúdo:

#!/bin/bash
module load openfoam/2012

# unpack input file
unzip openfoam-cavity.zip

blockMesh
icoFoam

#pack all results
zip cavity.zip *

Antes de submeter o job, deve-se tornar o script executável pelo comando

chmod +x run.sh

Para submeter o processo, basta usar o comando:

sbatch submit_serial_jobs.sh
