[slurm-users] Change primary alloc node

Hi, Is there a way to change/control the primary node (i.e. where the initial task starts) as part of a job's allocation. For eg, if a job requires 6 CPUs & its allocation is distributed over 3 hosts h1, h2 & h3 I find that it always starts the task in 1 particularnode (say h1) irrespective of h

Hello, Is there any DS in slurmctld which portrays the dynamic relative priority of pending jobs? We are trying to use slurm for developing a scheduling solution and 1 of the problems we face at the outset is how to determinethe order of scheduling for pending jobs. One option is to find schedul

[slurm-users] Job pre / post submit scripts

Hi, Is there an option in slurm to launch a custom script at the time of job submission through sbatchor salloc? The script should run with submit user permission in submit area. The idea is that we need to enquire something which characterises our job’s requirement like CPUslots, memory etc fro

[slurm-users] HOST CPUs not used by jobs

I have a SLURM configuration of 2 hosts with 6 + 4 CPUs. I am submitting jobs with sbatch -n . However, I see that even when I have exhausted all 10 CPU slots for the running jobs it's still allowing subsequent jobs to run ! The CPU slots availability is also show as full for the 2 hosts. No job

[slurm-users] Slurm Remote Task Launch

Hello, I have a slurm job which needs to launch multiple tasks across the allocated hosts for the job. My criteria is that most of the tasks need to be launched from within the main task launchedby slurm in the  launch compute node. So, if the allocated hosts are h1, h2 & h3 with h1 being the mai

Hi Daniel, Our jobs would have mutually exhaustive set of resources, though they may share hosts.Resources are mainly CPU cores on hosts.Private trackable resources can be defined according to needs & they would be exclusive to jobs too. Jobs, as I mentioned, can share hosts. Their resource gran

[slurm-users] Re: Custom Plugin Integration

Hi Daniel, Appreciate your response. I think you may be feeling that since we take the placement part of the scheduling to ourselves then Slurm has no other role to play! That's not quite true. Below in brief are other important roles which Slurm must perform which presently come to my mind(this

[slurm-users] Custom Plugin Integration

Hello, We wish to have a schedulingintegration with Slurm. Our own application has a backend system which willdecide the placement of jobs across hosts & CPU cores.  The backend takesits own time to come back with a placement (which may take a few seconds) & we expect slurm to update it regularl
