Description Kapil Sawate 2023-03-02 05:21:35 MST 
Hi 
We have a cluster of around 50k cores in which almost every job is an array jobs whose time of execution varies from 30s to max 24 hrs (80 % of jobs are 5-10 min jobs), slurm responsiveness get slows (squeue, sacct, sinfo sbatch)when there are too many no. of slurm calls like burst of job submission, cancellation, preemption etc. Can u please help us in fine tuning our cluster.

The slurmctld and slurmdbd are on the same linux server, the server configuration is 64 cores, 256gb of ram, all the slurm communications are over mellanox high speed ethernet (25Gb/s)
We have seen slurm sched threads 256, and slurm db queue length too high when the slurm operation slows down

The munge auth service is running with 10 threads
