I am new at PBS Pro and thank you in advance for your help.
I run Ubuntu 18.04 server version (no GUI) and I was able to install PBS Pro on the headnode following these instructions.
I also edited /etc/hosts file on both machine (headnode and node)
I also configured passwordless ssh connection between the headnode and the node.
All went well I am able to run PBS Pro command such as
$ qstat -B
Server Max Tot Que Run Hld Wat Trn Ext Status
eric9020-optiple 0 0 0 0 0 0 0 0 Idle
Now, I am trying to install PBS Pro on a client node (where the job will actually run) but I don’t seem to be able to find any information on Ubuntu 18.04. I understand that PBS Pro is very concentrated on CentOS but my cluster (12 nodes) are already been configured with Ubuntu 18.04 and OpenMPI.
I followed exactly the same steps for the headnode except for /etc/pbs.conf
I edited the pbs.conf file for the node as follow:
For the Headnode I edited the pbs.conf file as follow:
I edited the config for the PBS Pro client node to connect to the headnode (eric9020-optiplex)
I created a “nodes” file the on the headnode
/var/spool/pbs/server_priv# cat nodes
When I try to add a node with the following command
$ qmgr -c “create node knife11”
I have the following error:
qmgr obj=knife11 svr=default: Unauthorized Request
qmgr: Error (15007) returned from server
Thank you for your help
