This is my scontrol show node: NodeName=pez015 Arch=x86_64 CoresPerSocket=6 CPUAlloc=12 CPUErr=0 CPUTot=12 Features=(null) Gres=(null) NodeAddr=pez015 NodeHostName=pez015 OS=Linux RealMemory=48128 Sockets=2 State=ALLOCATED ThreadsPerCore=1 TmpDisk=61440 Weight=1 BootTime=2013-03-01T16:40:23 SlurmdStartTime=2013-03-01T16:41:04
Neither in sview I can find this information. Something may be missing in my slurm.conf? Slurm 2.4.3 2013/4/26 Danny Auble <d...@schedmd.com> > sview should also work.
