Ubuntu HPC Configure PBS job scheduler

Home > Ubuntu > HPC setup with openpbs and openmpi > Configure PBS job scheduler

1. Login to master node via root. Add nodes to PBS.

   qmgr  #Further on Qmgr: prompt use below
   
   create node <node1>
   create node <node2>

   This should be done for all compute nodes

2. Check PBS information. All three nodes should be visible

   pbsnodes -a

   To get only state information for all nodes, we can filter for state and node name via grep:

   pbsnodes -a | grep '^[^ ]\|state' | grep -v last

3. Create queue

   qmgr -c "create queue testq1 queue_type=execution"
   qmgr -c "set queue testq1 started=true"
   qmgr -c "set queue testq1 enabled=true"
   qmgr -c "set queue testq1 resources_default.nodes=1"
   qmgr -c "set queue testq1 resources_default.walltime=3600"

4. Set queue default values

   qmgr -c "set server default_queue = testq1"
   qmgr -c "set server scheduling=true"
   qmgr -c "set server job_history_enable=true"

5. Check server properties

   qmgr -c "print server"
