Hi all, Long time Torque user, first time SLURM user. I'm running version 15.08 from APT on Ubuntu Xenial. (running on an 18 core CPU E5-2697 v4)
I'm trying to figure out the proper slurm.conf configuration, and script parameters to run a job array on a single node/server workstation, with more than one concurrent task of the job running at the time. e.g. #!/bin/bash #SBATCH -o slurm_example-%A_%a.out #SBATCH --array=1-21%3 #SBATCH --mem-per-cpu=2000 f srun sleep 15 and submitting with $sbatch exmaple.sh, should run 21 total instances of sleep, 3 at a time, correct? I can never get more than 1 concurrent process going.... My slurm.conf file looks like; ControlMachine=localhost AuthType=auth/munge CacheGroups=0 CryptoType=crypto/munge MaxTasksPerNode=32 MpiDefault=none ProctrackType=proctrack/pgid ReturnToService=1 SlurmctldPidFile=/var/run/slurmctld.pid SlurmctldPort=6817 SlurmdPidFile=/var/run/slurmd.pid SlurmdPort=6818 SlurmdSpoolDir=/var/spool/slurmd SlurmUser=root StateSaveLocation=/var/spool SwitchType=switch/none TaskPlugin=task/none InactiveLimit=0 KillWait=30 MinJobAge=300 SlurmctldTimeout=120 SlurmdTimeout=300 Waittime=0 FastSchedule=1 SchedulerType=sched/backfill SchedulerPort=7321 SelectType=select/cons_res SelectTypeParameters=CR_CPU AccountingStorageType=accounting_storage/none AccountingStoreJobComment=YES ClusterName=cluster JobCompType=jobcomp/none JobAcctGatherFrequency=30 JobAcctGatherType=jobacct_gather/none SlurmctldDebug=3 SlurmdDebug=3 # COMPUTE NODES NodeName=localhost CPUs=1 RealMemory=120000 Sockets=1 CoresPerSocket=18 ThreadsPerCore=2 State=UNKNOWN PartitionName=debug Nodes=localhost Shared=YES DefMemPerCPU=3000 Default=YES MaxTime=INFINITE State=UP I've tried both; SelectType=select/cons_res SelectTypeParameters=CR_CPU and SelectType=select/linear but both return; sinfo -o %C CPUS(A/I/O/T) 0/0/1/1 which didnt seem right, because I thought if I sent SelectType=select/cons_res & SelectTypeParameters=CR_CPU, the threads should be seen as the CPUS I've tried to piece it together with the slurm and ubuntu mailing list, but two days later am ready to hide in a corner.... any info appreciated! ashton
