[Zainul Abiddin]

Hi All,

Please help me to submit a simple job on master and compute nodes.
Here is the my commands

[root at smaster ~]# sinfo -Nl

NODELIST   NODES PARTITION       STATE CPUS    S:C:T MEMORY TMP_DISK WEIGHT
AVAIL_FE REASON
smaster        1      hpc*        idle 4       4:1:1   1024        0      1
  (null) none
snode          1     debug        idle 4       4:1:1   1024        0      1
  (null) none

[root at smaster ~]# cat /etc/slurm/slurm.conf

NodeName=smaster NodeAddr=192.168.1.195 CPUs=4 RealMemory=1024 State=UNKNOWN
NodeName=snode NodeAddr=192.168.1.196 CPUs=4 RealMemory=1024 State=UNKNOWN
PartitionName=debug Nodes=snode Default=YES MaxTime=INFINITE State=UP
PartitionName=hpc Nodes=smaster Default=YES MaxTime=INFINITE State=UP

[root at smaster ~]#

and how do I configure a single partition for two nodes.
