== 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.
