Hello All, I'm facing some issues to use the HT on my compute nodes, I'm running slurm 17.02.7
SelectTypeParameters = CR_CORE_MEMORY cgroup.conf CgroupAutomount=yes CgroupReleaseAgentDir="/etc/slurm/cgroup" # cpuset subsystem ConstrainCores=yes TaskAffinity=no # memory subsystem ConstrainRAMSpace=yes ConstrainSwapSpace=yes # device subsystem ConstrainDevices=yes If I try to allocate the 80 CPUs it will not work, I couldn't find why this doesn't work. Do you guys have any ideas or could cause this issue? I've been playing with several different parameters on the node definition, also using --threads-per-core, etc.. but still I should be able to allocate the 80 cpus. Thanks in advance. srun --reservation=test_ht -p defq -n 80 sleep 100 srun: error: Unable to allocate resources: Requested node configuration is not available -------------- [root@csk007 ~]# slurmd -C NodeName=csk007 CPUs=80 Boards=1 SocketsPerBoard=2 CoresPerSocket=20 ThreadsPerCore=2 RealMemory=385630 TmpDisk=217043 UpTime=84-00:36:44 [root@csk007 ~]# scontrol show node csk007 NodeName=csk007 Arch=x86_64 CoresPerSocket=20 CPUAlloc=0 CPUErr=0 CPUTot=80 CPULoad=4.03 AvailableFeatures=(null) ActiveFeatures=(null) Gres=(null) NodeAddr=csk007 NodeHostName=csk007 Version=17.02 OS=Linux RealMemory=380000 AllocMem=0 FreeMem=338487 Sockets=2 Boards=1 State=RESERVED ThreadsPerCore=2 TmpDisk=0 Weight=1 Owner=N/A MCS_label=N/A Partitions=defq BootTime=2018-09-14T12:31:05 SlurmdStartTime=2018-11-29T15:25:03 CfgTRES=cpu=80,mem=380000M AllocTRES= CapWatts=n/a CurrentWatts=0 LowestJoules=0 ConsumedJoules=0 ExtSensorsJoules=n/s ExtSensorsWatts=0 ExtSensorsTemp=n/s ----------------------- -- Best Regards, Sidiney
