Hi,

I have never done a HPC before, it is all new to me so I can be making "newbie errors".   The old HPC has been dumped on us so I am trying to build it "professionally" shall we say  ie documented, stable and I will train ppl to build it  (all this with no money at all). 

My understanding is a login as a normal user and run a job, and this worked for me last time. It is possible I have missed something,

[xxxjonesst@xxx.ac.nz@xxxunicoslurmd1 ~]$ cat testjob.sh
#!/bin/bash
#
#SBATCH --job-name=test
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=1
#SBATCH --mem=1G
#SBATCH --partition=debug
#SBATCH --time=00:10:00
#SBATCH --output=%x_%j.out
#SBATCH --error=%x_%j.err

echo "Hello World"
echo "Hello Error" 1>&2

This worked on a previous setup the outputs were in my home directory on the NFS server as expected.   

regards

Steven

Looking at the code that seems to come from this code:

         if (!_slurm_authorized_user(msg->auth_uid)) {
                 error("Security violation, batch launch RPC from uid %u",
                       msg->auth_uid);
                 rc = ESLURM_USER_ID_MISSING;  /* or bad in this case */
                 goto done;
         }


and what it is calling is:

/*
  *  Returns true if "uid" is a "slurm authorized user" - i.e. uid == 0
  *   or uid == slurm user id at this time.
  */
static bool
_slurm_authorized_user(uid_t uid)
{
         return ((uid == (uid_t) 0) || (uid == slurm_conf.slurm_user_id));
}


Is it possible you're trying to run Slurm as a user other than root or
the user designated as the "SlurmUser" in your config?

Also check that whoever you have set as the SlurmUser has the same UID
everywhere (in fact everyone should do).

All the best,
Chris
