Adding/removing nodes to PBS

To add a node to PBS, run as root the script ~davidg/bin/mk_pbsnode on the PBS server and pipe its output to qmgr.

Syntax of this script:

mk_pbsnode -np <number_of_processors> -p <node-type> -p <OS> -p xps<speed> <hostname>

For example:

root@tbn20# ~davidg/bin/mk_pbsnode -np 2 -p amdncf -p rhel3 -p xps2000 node16-66.farmnet.nikhef.nl
# creating node node16-66.farmnet.nikhef.nl
create node node16-66.farmnet.nikhef.nl
set node node16-66.farmnet.nikhef.nl properties += farm
set node node16-66.farmnet.nikhef.nl properties += amdncf
set node node16-66.farmnet.nikhef.nl properties += rhel3
set node node16-66.farmnet.nikhef.nl properties += xps2000
set node node16-66.farmnet.nikhef.nl ntype = cluster
set node node16-66.farmnet.nikhef.nl np = 2

To delete a node, run the script (as root on the PBS server) with the following syntax:

root@tbn20# ~davidg/bin/mk_pbsnode -d <hostname> | qmgr

NOTE: Deleting a node with the above commands kills pbs_server in torque 2.0.0. Taking a node offline can be done with

pbsnodes -o <hostname>

and bringing it back online via

pbsnodes -c <hostname>
