[slurm-users] Specify number of cores only?

ntasks=N as an argument to sbatch or srun? Should work as long as you don’t have exclusive node settings. From our setup:

[renfro at login ~]$ hpcshell --ntasks=16 # hpcshell is a shell function for 'srun --partition=interactive $@ --pty bash -i'
[renfro at gpunode001(job 202002) ~]$ srun hostname | sort | uniq -c
     12 gpunode001
      4 gpunode002
[renfro at gpunode001(job 202002) ~]$
