Install PBSPRo on a single node

Users/Site Administrators
#1

Dear All,

I am new in using PBS system. I followed the steps to compile from the source code and started the PBS without seemingly any problem from this link.

I want to install the PBSPro in only one node (one single desktop computer), i.e. compute node, execute node and head node become in one node. Is that possible?

OS: OpenSUSE 42.3

sudo /etc/init.d/pbs start

/opt/pbs/sbin/pbs_comm ready (pid=5292), Proxy Name:hostname:17001, Threads:4
PBS comm
PBS mom
Creating usage database for fairshare.
PBS sched
Connecting to PBS dataservice…connected to PBS dataservice@hostname
Licenses valid for 10000000 Floating hosts
PBS server

but there is some problem

pbsnodes -a
pbsnodes: Server has no node list

qmgr -c “create node hostname”
qmgr obj=hostname svr=default: Unauthorized Request
qmgr: Error (15007) returned from server

sudo qmgr -c “create node hostname”
sudo: qmgr: command not found

qsub scriptfile.sh
qsub: No default queue specified

the hostname is pingable and the firewall has been turned off

/etc/pbs.conf

PBS_START_COMM=1
PBS_START_MOM=1

PBS_CORE_LIMIT=unlimited
PBS_SCP=/usr/bin/scp

Please let me know whether I have wrong configuration file or I have some mistakes or I skip some installation steps. I greatly appreciate anyone help

Please run these commands:
#source /etc/profile.d/pbs.sh
#qmgr -c "create node "
< Hostname of the Compute Node > is actually the output of the hostname command on the compute node

hostname - - should be replaced with output of the hostname command on that compute node

Please share the contents of the scriptfile.sh and output of this below command qstat -Bf and qmgr -c ‘p s’

The PATH variable to the /opt/pbs/bin is not set , hence the issue. Please set it  or use as below
   
 #source /etc/profile.d/pbs.sh
    #qmgr 

    or 
    use   /opt/pbs/bin/qmgr     
    similarly, use  /opt/pbs/bin/qstat

Thank you

Thanks, now it is hopefully working

Creating a queue. qmgr: cannot connect
#4

Perfect ! Nice one !

To create a queue:

qmgr -c “create queue workq queue_type=e,started=t,enabled=t”

To set default queue, if no queue is requested in the job request, it will directly go to this queue:

qmgr -c “set server default_queue=workq”

These additional attributes would be helpful

qmgr -c  "set server job_history_enable = true"
qmgr -c "set server flatuid=true"

How to request a queue while submitting a job?

qsub -q workq

or in the script using the directive

#!/bin/sh
#PBS -q workq
echo “Working directory is $PWD”
