    v11 v12  
    6060With our SLURM script complete, we’re ready to run our program on the cluster. To submit our script to SLURM, we invoke the “sbatch” command. Suppose we saved our script in the file helloworld.srun (the extension is not important). Then our submission would look like:
    6161
    62 [[Image(sbatch.png, 50%)]]
     62[[Image(sbatch.png, 50%, center)]]
    6363
    6464Our job was successfully submitted and was assigned the job number 6041. We can check the output of our job by examining the contents of our output and error files. Referring back to the helloworld.srun SLURM script, notice the lines
     
    7171These specify files in which to store the output written to standard out and standard error, respectively. If our code ran without issue, then the Hi.err file should be empty and the Hi.out file should contain our greeting.

    73 [[Image(Hi_output.png, 50%)]]
     73[[Image(Hi_output.png, 50%, center)]]

    7575There are two more commands we should familiarize ourselves with before we begin. The first is the “squeue” command. This shows us the list of jobs that have been submitted to SLURM that are either currently running or are in the queue waiting to run. The last is the “scancel” command. This allows us to terminate a job that is currently in the queue. So that we can see these commands in action, let’s extend our jobs run time by adding a sleep command to the end of our SLURM script.
