#! Example SLURM job script for Wilkes2 (Broadwell, ConnectX-4, P100)

#!#############################################################
#!#### Modify the options in this section as appropriate ######
#!#############################################################

#! sbatch directives begin here ###############################
#! Name of the job:
#SBATCH -J run-meld
#! Which project should be charged (NB Wilkes2 projects end in '-GPU'):
#SBATCH -A CORE-WCHN-MELD-SL2-GPU   # CORE-WCHN-MELD-SL2-GPU  # use CORE-WCHN-MELD-SL2-CPU for CPU only run
#! How many whole nodes should be allocated?
#SBATCH --nodes=1
#SBATCH --gres=gpu:1
#! How many (MPI) tasks will there be in total?
#! Note probably this should not exceed the total number of GPUs in use.
#SBATCH --ntasks=1
#! How much wallclock time will be required?
#SBATCH --time=04:00:00  #TODO change back to 1hour
#! What types of email messages do you wish to receive?
#SBATCH --mail-type=FAIL
#! Uncomment this to prevent the job from being requeued (e.g. if
#! interrupted by node failure or system downtime):
##SBATCH --no-requeue
#! Submit a job array with index values between 0 and 31
#! NOTE: This must be a range, not a single number (i.e. specifying '32' here would only run one job, with index 32)
#! In our case, this is controlled by an explicit command line argument when calling the script (--array 0-1)
#SBATCH --array=0-49

#! Do not change:
#SBATCH -p pascal

#! sbatch directives end here (put any additional directives above this line)

#! Notes:
#! Charging is determined by GPU number*walltime. 

#! Number of nodes and tasks per node allocated by SLURM (do not change):
numnodes=$SLURM_JOB_NUM_NODES
numtasks=$SLURM_NTASKS
mpi_tasks_per_node=$(echo "$SLURM_TASKS_PER_NODE" | sed -e  's/^\([0-9][0-9]*\).*$/\1/')
#! ############################################################
#! Modify the settings below to specify the application's environment, location 
#! and launch method:

#! Optionally modify the environment seen by the application
#! (note that SLURM reproduces the environment at submission irrespective of ~/.bashrc):
. /etc/profile.d/modules.sh                # Leave this line (enables the module command)
module purge                               # Removes all modules still loaded
module load rhel7/default-gpu              # REQUIRED - loads the basic environment

#! Insert additional module load commands after this line if needed:
module load miniconda/3

#! Full path to application executable:
CONDA_PATH="$HOME/.conda/envs/meld"
MELD_PATH="$HOME/software/meld_classifier"
application="source activate $CONDA_PATH; $CONDA_PATH/bin/python $MELD_PATH/scripts/classifier/test_and_stats.py --split $SLURM_ARRAY_TASK_ID --n-splits $n_splits --experiment-folder $experiment_folder --experiment-name $experiment_name --fold $fold $plot_images $saliency $save_per_split_files --test-mode $test_mode"

#! Run options for the application:
options=""

#! Work directory (i.e. where the job will run):
workdir="$SLURM_SUBMIT_DIR"  # The value of SLURM_SUBMIT_DIR sets workdir to the directory
                             # in which sbatch is run.

#! Are you using OpenMP (NB this is unrelated to OpenMPI)? If so increase this
#! safe value to no more than 12:
export OMP_NUM_THREADS=1

#! Number of MPI tasks to be started by the application per node and in total (do not change):
np=$[${numnodes}*${mpi_tasks_per_node}]

#! Choose this for a pure shared-memory OpenMP parallel program on a single node:
#! (OMP_NUM_THREADS threads will be created):
CMD="$application $options"

#! Choose this for a MPI code using OpenMPI:
#CMD="mpirun -npernode $mpi_tasks_per_node -np $np $application $options"
