To setup OpenPBS master on HPC master node use following steps:

  1. Install postgresql 
    apt install postgresql postgresql-server-dev-all postgresql-contrib
  2. Download and install PBS using: 
    cd /export/apps/temp
wget https://github.com/openpbs/openpbs/releases/download/v20.0.1/openpbs_20.0.1.ubuntu_1804.zip
unzip openpbs_20.0.1.ubuntu_1804.zip
cd /export/apps/temp/openpbs_20.0.1.ubuntu_1804/
dpkg -i openpbs-server_20.0.1-1_amd64.deb
  3. Edit '/etc/pbs.conf' file should be look like below: 
    PBS_EXEC=/opt/pbs
PBS_SERVER=<master-hostname>
PBS_START_SERVER=1
PBS_START_SCHED=1
PBS_START_COMM=1
PBS_START_MOM=0
PBS_HOME=/var/spool/pbs
PBS_CORE_LIMIT=unlimited
PBS_SCP=/bin/scp
PBS_LEAF_NAME=<master-hostname>
    Here 'PBS_START_MOM=0' and not having master in nodes list (Point below) ensures that jobs execute only on compute nodes. If we want jobs to execute on master node then we should have 'PBS_START_MOM=1' and also master should be part of node list '/var/spool/pbs/server_priv/nodes'.
  4. Set the environment 
    source /etc/profile.d/pbs.sh
    

    source /etc/pbs.conf
  5. Enter master hostname in /var/spool/pbs/mom_priv/config file 
    $clienthost <rocks-master-hostname>      //Ex: master
  6. In pbs server, needs to specify all the compute/gpu nodes in /var/spool/pbs/server_priv/nodes 
    node1
    

    node2
  7. Start and enable pbs 
    systemctl start pbs
    

    systemctl enable pbs
