I have access to a cluster, which contains several nodes, node01,node02, etc. The administrator has configured the Slurm profile of the cluster. When I run a script, it seems Slurm randomly assign a node for me.
Now, I want to run my program on a specific node, e.g. node01. As I do not have the admin privilege, I can only edit the profile of my own, under the menu Parallel->Manage cluster profile->edit. The only option that maybe related to node selecttion is the last one, i.e. cmd line arg.
Can I add cmd line arg to run my job on a specific node? Or is there any other configuration that non-admin user can edit?

Based on this stackexchange answer https://unix.stackexchange.com/questions/443438/how-to-submit-a-job-to-a-specific-node-using-slurms-sbatch-command what you need to do is set the SubmitArguments in the Cluster Profile Manager to
--nodelist=node01
This is mentioned in the SLURM documentation for srun: https://slurm.schedmd.com/srun.html .
