Hi Leon,<br>
<br>
depends on how the admins configured slurm. If they set
select/linear, you have no chance to get just a core, as slurm will
schedule only complete nodes.<br>
<br>
Nonetheless, you omitted to tell slurm, how much memory you need (at
least there is nothing in your script). Slurm will then also
schedule a complete node.<br>
Please try something like --mem=1024. This will restrict your job to
1 GB memory. If you need more, you'll have to specify more.<br>
<br>
<br>
Best<br>
