How to Submit Interactive jobs
There are different ways to submit interactive jobs.
Using sinteractive
You can use the custom tool sinteractive as:
[xwang@pitzer-login04 ~]$ sinteractive salloc: Pending job allocation 14269 salloc: job 14269 queued and waiting for resources salloc: job 14269 has been allocated resources salloc: Granted job allocation 14269 salloc: Waiting for resource configuration salloc: Nodes p0591 are ready for job ... ... [xwang@p0593 ~] $ # can now start executing commands interactively
Using salloc
It is a little complicated if you use salloc . Below is a simple example:
[user@pitzer-login04 ~] $ salloc -t 00:30:00 --ntasks-per-node=3 srun --pty /bin/bash salloc: Pending job allocation 2337639 salloc: job 2337639 queued and waiting for resources salloc: job 2337639 has been allocated resources salloc: Granted job allocation 2337639 salloc: Waiting for resource configuration salloc: Nodes p0002 are ready for job # normal login display [user@p0002 ~]$ # can now start executing commands interactively
How to Submit Non-interactive jobs
Submit Slurm job Script
A job can be submitted non-interactively via a Slurm job script. Below is a simple Slurm job script slurm_job.sh that calls for a parallel run:
#!/bin/bash
#SBATCH --time=1:00:00
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=40
#SBATCH --job-name=hello
#SBATCH --account=PZS0712
cd $SLURM_SUBMIT_DIR
module load intel
mpicc -O2 hello.c -o hello
srun ./hello > hello_results
Submit this script using the command sbatch slurm_job.sh , and this job is scheduled successfully as shown below:
[xwang@cardinal-login04 slurm]$ sbatch slurm_job.sh
Submitted batch job 421618
Check the Job
You can use the jobscript command to check the job information:
[xwang@cardinal-login04 slurm]$ jobscript 421618
----- BEGIN jobid=421618 workdir=/users/oscgen/xwang/slurm -----
#!/bin/bash
#SBATCH --time=1:00:00
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=40
#SBATCH --job-name=hello
#SBATCH --account=PZS0712
cd $SLURM_SUBMIT_DIR
module load intel
mpicc -O2 hello.c -o hello
srun ./hello > hello_results
----- END jobid=421618 workdir=/users/oscgen/xwang/slurm -----
