[slurm-users] heterogeneous jobs using packjob

[Jing Gong]

Hi,

I can submit heterogeneous jobs  using packjob likes

....
#SBATCH -p high_mem
#SBATCH -N 1
#SBATCH --exclusive
#SBATCH packjob
#SBATCH -p log_mem
#SBATCH  -N 2
#SBATCH --exclusive
....
i.e. specify 1 fat node and two thin nodes for one jobs. 

If I use "squeue/scontrol" to check the job, it indeed distribute 3 nodes, However, if set SLURM environment variables in the job script, I always get the information of the first partition "high_mem".

echo $SLURM_NNODES               # 1
echo $SLURM_JOB_NODELIST   # p01k30

How can I obtain the information of the two type nodes in a job script to run different applications on different nodes?

Thanks a lot. /Jing
