Hi Nicholas,
first of all, "Happy new Year".
I'm not sure, what you want to achieve. If you want to
a) schedule whole nodes all the time (e.g. also for serial jobs), your
config seems on first sight ok.
b) schedule multiple serial jobs on the same node, you will have to replace
SelectType=select/linear
with
SelectType=select/cons_res or SelectType=select/cons_tres
You will also have to select one of the SelectTypeParameters, depending
on your needs.
Best

Hi,
I am new to SLURM
I am experimenting with a small cluster, 1 head node (with GPU for
visualization, not for CUDA jobs yet) and 2 compute nodes
Each machine have quad core processors but no hyperthreading.
I have the following test job:
---------------------------------------------------------------------
#!/bin/bash
#SBATCH --job-name=producer # Job name
#SBATCH --output=producer.%j.log # Standard output and error log
#SBATCH --cpus-per-task=1
/mnt/nfs/projects/workflow-languages/build/producer
output.$SLURM_JOB_ID.txt
---------------------------------------------------------------------
My slurm.conf is this, is the configuration wrong ?
