Ubuntu HPC Setup PBS master on master node

Home > Ubuntu > HPC setup with openpbs and openmpi > Setup PBS master on master node

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
