### e.g. request 4 nodes with 1 gpu each, totally 4 gpus (WORLD_SIZE==4)
### Note: --gres=gpu:x should equal to ntasks-per-node
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=1
#SBATCH --gres=gpu:a100:1

#SBATCH --output=/mnt/lustre/mladm/mfa252/%x-%j.out

### change 5-digit MASTER_PORT as you wish, slurm will raise Error if duplicated with others
### change WORLD_SIZE as gpus/node * num_nodes
export MASTER_PORT=18120
export WORLD_SIZE=2

### get the first node name as master address - customized for vgg slurm
### e.g. master(gnodee[2-5],gnoded1) == gnodee2
echo "NODELIST="${SLURM_NODELIST}
master_addr=$(scontrol show hostnames "$SLURM_JOB_NODELIST" | head -n 1)
export MASTER_ADDR=$master_addr
