Have you defined the TmpDisk value for each node? As far as I know, local disk space is not a valid type for GRES.
https://slurm.schedmd.com/gres.html "Generic resource (GRES) scheduling is supported through a flexible plugin mechanism. Support is currently provided for Graphics Processing Units (GPUs), CUDA Multi-Process Service (MPS), and Intel® Many Integrated Core (MIC) processors." The only valid solution I've found for scratch is to: In slurm.conf, define the location of local scratch globally via TmpFS. And then the amount per host is defined via TmpDisk=xxx. Then the request for srun/sbatch via --tmp=X --- Erik Ellestad Wynton Cluster SysAdmin UCSF ________________________________ From: slurm-users <slurm-users-boun...@lists.schedmd.com> on behalf of navin srivastava <navin.alt...@gmail.com> Sent: Tuesday, April 14, 2020 7:32 AM To: Slurm User Community List <slurm-users@lists.schedmd.com> Subject: Re: [slurm-users] How to request for the allocation of scratch . Any suggestion on the above query.need help to understand it. Does TmpFS=/scratch and the request is #SBATCH --tmp=500GB then it will reserve the 500GB from scratch. let me know if my assumption is correct? Regards Navin.

Then i have opted the mechanism of gres.conf GresTypes=gpu,scratch and defined each node the scratch value and then requested using --gres=lscratch:10GB but in this scenario if requesting both gres resources gpu as well as scratch it show me only scratch in my Gres resource not gpu. does it using the gpu also as a gres resource? could anybody please advice which is the correct method to achieve the same? Also, is scratch will be able to calculate the actual usage value on the node. REgards Navin.
