Hi Leon,
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.
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.
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.
Best

Dear there,
I wrote an analytic program to analyze my data. The analysis costs
around twenty days to analyze all data for one species. When I submit
my job to the cluster, it always request one node instead of one CPU.
I am wondering how I can ONLY request one CPU using “sbatch” command?
Below is my batch file. Any comments and help would be highly
appreciated.
Appreciatively,
Leon

Where wcnqn.auto.pl is my program. 9625 denotes the species number.
