This README describes how to get the most basic working
|
|
torque service on a single host.
|
|
|
|
To setup a basic single-node localhost-only batch system, install the
|
|
torque-server, torque-mom, and torque-scheduler packages, and do something like
|
|
this:
|
|
|
|
0) If torque is built with munge support then this
|
|
must be enabled first on all nodes. The munge
|
|
package should allready be installed.
|
|
|
|
Create a munge key with
|
|
|
|
/usr/sbin/create-munge-key
|
|
|
|
Copy resulting key /etc/munge/munge.key to
|
|
all torque nodes in your cluster including
|
|
pbs_server, pbs_mom and client (qstat,qsub) nodes.
|
|
|
|
1) Get your full hostname with
|
|
|
|
# /bin/hostname --long
|
|
|
|
e.g myhost.example.org
|
|
|
|
2) Edit /etc/torque/server_name
|
|
to contain the single line
|
|
|
|
myhost.example.org
|
|
|
|
3) Edit /etc/torque/mom/config
|
|
to contain the single line
|
|
|
|
$pbsserver myhost.example.org
|
|
|
|
4) Create a torque serverdb file.
|
|
# /usr/sbin/pbs_server -D -t create
|
|
|
|
Warning this will remove any existing serverdb
|
|
file located at /var/lib/torque/server_priv/serverdb
|
|
|
|
You will have to Ctrl^C the pbs_server command, it will
|
|
only take a moment to create this file.
|
|
|
|
5) Start the pbs_server and configure it.
|
|
service pbs_server start
|
|
# qmgr -c "s s scheduling=true"
|
|
# qmgr -c "c q batch queue_type=execution"
|
|
# qmgr -c "s q batch started=true"
|
|
# qmgr -c "s q batch enabled=true"
|
|
# qmgr -c "s q batch resources_default.nodes=1"
|
|
# qmgr -c "s q batch resources_default.walltime=3600"
|
|
# qmgr -c "s s default_queue=batch"
|
|
|
|
6) Add one batch worker to your pbs_server.
|
|
|
|
# qmgr -c "c n myhost.example.org"
|
|
|
|
7) Start the pbs_mom and pbs_sched deamons.
|
|
|
|
# service pbs_mom start
|
|
# service pbs_sched start
|
|
|
|
8) Use chkconfig to start the services at boot time.
|
|
|
|
# /sbin/chkconfig pbs_mom on
|
|
# /sbin/chkconfig pbs_server on
|
|
# /sbin/chkconfig pbs_sched on
|
|
# /sbin/chkconfig munge on
|
|
|
|
9) Submit a test job.
|
|
As a user not as root run the following
|
|
|
|
$ qsub <<EOF
|
|
hostname
|
|
echo "Hi I am a batch job running in torque"
|
|
EOF
|
|
|
|
10 ) Monitor the state of that job with qstat.
|
|
|
|
In case of problems first of all look in /var/log/torque
|
|
|
|
