Interactive jobs

Starting an interactive job

Using original slurm command

SSH
srun --partition=debug --pty --nodes=1 --ntasks-per-node=16 --cores-per-socket=4 \
     --threads-per-core=4 --sockets-per-node=1 --mem-per-cpu=1200 --gres=gpu:v100:1 \
     --time 01:30:00 --wait=0 --export=ALL /bin/bash

Using slurm wrapper suite command

SSH
swrun -p gpux1
Keeping interactive jobs alive

Interactive jobs cease when you disconnect from the login node either by choice or by internet connection problems. To keep an interactive job alive you can use a terminal multiplexer like tmux.

You start tmux on the login node before you get an interactive slurm session with srun and then do all the work in it. In case of a disconnect you simply reconnect to the login node and attach to the tmux session again by typing:

SSH
tmux attach

or in case you have multiple session running:

SSH
tmux list-session
tmux attach -t <session_id>

Batch jobs

submit job with

SSH
#!/bin/bash
#SBATCH --job-name="demo"
#SBATCH --output="demo.%j.%N.out"
#SBATCH --error="demo.%j.%N.err"
#SBATCH --partition=gpux1
#SBATCH --time=4
 
srun hostname
