+```
+
+**Then, go SLURM**
+```
+17:01:47 [ctchiling@pollux ~]# cd view/HPC/SLURM
+
+**Then, create a file name's running**
+#mkdir running
+#./sequential/sequential.slurm ./sleep.slurm
+#nano sleep.slurm
+```
+In this text you write:
+```
+" GNU nano 2.3.1                                          File: sleep.slurm                                                                                            
+
+#!/usr/bin/env bash
+#SBATCH --job-name=waste
+#SBATCH --partition=seq
+#SBATCH --time=0:20:0

+#SBATCH --error  %x.%j.err
+
+echo "This job was launch from $SLURM_SUBMIT_HOST in $SLURM_SUBMIT_DIR"
+
+sleep 300
+"
+```
+Your commande sleeps while 5 minutes.
+
+**Then** 
+
+```
+#[ctchiling@pollux running]# sbatch sleep.slurm 
+
+Submitted batch job 33691086
+
+
+[ctchiling@pollux running]# squeue -u ctchiling

+
+```
+
+Now you can enter in the x011 node:
+```
+#[ctchiling@x011 ~]$ ssh x011
+#Last login: Thu Feb 18 17:25:49 2021 from pollux
