[slurm-users] Using "Nodes" on script - file ????

[Matthias Krawutschke]

Hello together,

I have a special question regarding the variables:

 

#SBATCH -nodes = 2     or SRUN -N
.

 

Some users of the HPC set these WORTH very high and allocate the
ComputeNode, although with that they do not require this at all.

 

My question is the following now:

Is it really necessary that this value must be put in the script,
command-line or this can be left out?

In which case is it necessary to limit these? at OpenMPI possible?

 

Best regards
.
