I saw you got some good answers, but a quick note on mpi. For some of
them, you are compiling it yourself, they can be "slurm-aware" (eg:
openmpi). Then when you do 'mpirun' it automatically knows your
inherited hostlist and you need do nothing extra when running.

Hi,
Is there any slurm variable to read the node names of a partition?
There is an MPI option --hostfile which we can write the node names.
I want to use something like this in the sbatch script:
#SBATCH --partition=MYPART
... --hostfile $SLURM_NODES_IN_PARTITION ....
I can manually manipulate the output of scontrol to extract node
names. Like this:
[mahmood@rocks7 ~]$ scontrol show partition MYPART | grep -w Nodes |
cut -d '=' -f 2
compute-0-[4-6]
But that basically is not
compute-0-4
compute-0-5
compute-0-6
Which I have to post process more. Any better idea?
