Set up torque/PBS

This section describes how to set up torque PBS. If it's already set up, skip this section. First, we install the torque PSB system:

apt-get install torque-server torque-scheduler torque-mom torque-client

Then stop all the running torque processes:

/etc/init.d/torque-mom stop
/etc/init.d/torque-scheduler stop
/etc/init.d/torque-server stop

Create the PBS server (say "yes" when prompted):

pbs_server -t create

Then kill the PBS server process:

killall pbs_server

Set up the PBS server:

echo $(hostname -f) > /etc/torque/server_name
echo $(hostname -f) >  /var/spool/torque/server_priv/acl_svr/acl_hosts
echo $(hostname -f) > /var/spool/torque/mom_priv/config

echo root@$(hostname -f) > /var/spool/torque/server_priv/acl_svr/operators
echo root@$(hostname -f) > /var/spool/torque/server_priv/acl_svr/managers

echo "$(hostname -f) np=4" > /var/spool/torque/server_priv/nodes

If you have a line in your /etc/hosts file that resolves your hostname to 127.0.1.1, you have to comment it out, e.g.

#127.0.1.1  console.grid.orbit-lab.org  console

Once you've done that, start everything back up again:

/etc/init.d/torque-server start
/etc/init.d/torque-scheduler start
/etc/init.d/torque-mom start

Now we'll set up some configuration values:

qmgr -c "set server scheduling = True"
qmgr -c "set server acl_host_enable = True"
qmgr -c "set server acl_hosts = $(hostname -f)"
qmgr -c "set server allow_node_submit = True"

You'll have to run the commands above as root, since you've set up the root user as the only PBS operator and manager.
