It looks like you didn't install the RPM with Slurm plugins.
Quoting David Lin <[email protected]>:
Hello, I am having some issues with the select/cons_res mode of slurm. When I tried to execute a job such as srun -N 2 -n 2 hostname, I get this $ srun -N 2 -n 2 -q RHEL6 hostname srun: error: slurm_receive_msg: Zero Bytes were transmitted or received srun: error: Unable to allocate resources: Zero Bytes were transmitted or received and on the slurmctld log, I see this [2015-05-07T16:52:43.264] error: we don't have select plugin type 102 [2015-05-07T16:52:43.264] error: select_g_select_jobinfo_unpack: unpack error [2015-05-07T16:52:43.264] error: Malformed RPC of type REQUEST_RESOURCE_ALLOCATION(4001) received [2015-05-07T16:52:43.264] error: slurm_receive_msg: Header lengths are longer than data received [2015-05-07T16:52:43.274] error: slurm_receive_msg: Header lengths are longer than data received All of the nodes as well as the controller running slurmctld have the exact same slurm.conf, and I've included the relevant section below. # SCHEDULING #DefMemPerCPU=0 FastSchedule=0 #MaxMemPerCPU=0 #SchedulerRootFilter=1 #SchedulerTimeSlice=30 SchedulerType=sched/backfill SchedulerPort=7321 SelectType=select/cons_res SelectTypeParameters=CR_Core_Memory Is there some configuration I'm missing? Thank you! David
