Launch script for matlab with GPU

shell_matlab.sh

#!/bin/sh
#
# stdout/stderr redirection
#PBS -N NAME_OF_JOB1
#PBS -o $PBS_JOBNAME.$PBS_JOBID.out
#PBS -e $PBS_JOBNAME.$PBS_JOBID.err
#PBS -l nodes=1:gpus=1
# Execute the job from  the  current  working  directory
cd $PBS_O_WORKDIR

ML_GPUDEVICE=`sed 's/^.*gpu//' $PBS_GPUFILE`
export ML_GPUDEVICE

echo -n gpu${ML_GPUDEVICE}@
/bin/hostname

matlab -nodisplay -logfile test.out -r "gpuDevice(str2num(getenv('ML_GPUDEVICE')) + 1); myscript" 

You need to run the script through the dtu server system

For debugging GPU code you can run matlab in desktop mode by:

1. From the terminal request a GPU

  gpush -l nodes=1:gpus=1 -v DISPLAY -q hpc

2. Run the following shell script

#!/bin/sh
#
ML_GPUDEVICE=`sed 's/^.*gpu//' $PBS_GPUFILE`
export ML_GPUDEVICE
echo -n gpu${ML_GPUDEVICE}@/bin/hostname
matlab -r "gpuDevice(str2num(getenv('ML_GPUDEVICE')) + 1); desktop"

3. In matlab test that you have a GPU

a = gpuArray.zeros(10,10);
gpuDevice()
