Function	DNS	IP	Comments
User interface node	cluster.gcc.rug.nl	195.169.22.156	Login node to submit and inspect jobs. Relatively powerful machine. Users can run code outside the scheduler for debugging purposes.
scheduler VM	scheduler01	195.169.22.214	Runs Torque's pbs_server resource manager and the maui scheduler.
scheduler VM	scheduler02	195.169.22.190	Runs Torque's pbs_server resource manager and the maui scheduler.
Execution node	targetgcc01	192.168.211.191	Runs Torque's pbs_mom Dedicated test node: only the test-short and test-long queues run on this node. Crashing the test node shall not affect production!.
Execution node	targetgcc02	192.168.211.192	Runs Torque's pbs_mom Production node: only the default gcc and priority gaf queues run on this node.

PBS software / flavour

The current setup uses the resource manager Torque 2.5.12 combined with the scheduler Maui 3.3.1.

Maui

Runs only on the schedulers with config files in

/usr/local/maui/

Torque

Torque clients are available on all servers.
Torque's pbs_server deamon runs only on the schedulers.
Torque's pbs_mom daemon runs only on the execution nodes where the real work is done.
Torque config files are installed in

/var/spool/torque/

Dual scheduler setup
