[slurm-users] Serial jobs on multi-core nodes using whole compute node

[Nicholas Yue]

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 ?
