I am running a slurm client on a virtual machine. The virtual machine originally had a core count of 10. But I have now increased the cores to 16, but "slurmd -C" continues to show 10. I have increased the core count in the slurm.conf file. and that is being seen correctly. The state of the node is stuck in a Drain state because of this conflict. How do I get slurmd -C to see the new number of cores?
I'm running slurm 18.08. I have tried running "scontrol reconfigure" on the head node. I have restarted slurmd on all the client nodes, and I have restarted slurmctld on the master node. Where is the data about compute note CPUs stored? I can't seem to find a config or setting file on the compute node. The compute node that I am working on is "liverpool" *mtie@liverpool** ~ $* slurmd -C NodeName=liverpool CPUs=10 Boards=1 SocketsPerBoard=10 CoresPerSocket=1 ThreadsPerCore=1 RealMemory=64263 UpTime=1-21:55:36 *mtie@liverpool** ~ $* lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 16 On-line CPU(s) list: 0-15 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 4 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 15 Model: 6 Model name: Common KVM processor Stepping: 1 CPU MHz: 2600.028 BogoMIPS: 5200.05 Hypervisor vendor: KVM Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 4096K L3 cache: 16384K NUMA node0 CPU(s): 0-15 Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx lm constant_tsc nopl xtopology eagerfpu pni cx16 x2apic hypervisor lahf_lm *mtie@liverpool** ~ $* more /etc/slurm/slurm.conf | grep liverpool NodeName=*liverpool* NodeAddr=137.22.10.202 CPUs=16 State=UNKNOWN PartitionName=BioSlurm Nodes=*liverpool* Default=YES MaxTime=INFINITE State=UP *mtie@liverpool** ~ $* sinfo -n liverpool -o %c CPUS 16 *mtie@liverpool** ~ $* sinfo -n liverpool -o %E REASON Low socket*core*thread count, Low CPUs Any advice?
