How to configure a TORQUE PBS resource

In order to configure a TORQUE/PBS cluster accessed through ssh protocol, you should follow the next steps:

1. Configure the meteo resource. If you do not have a [wiki:DRM4G#Resourcesection private_key] file, you can generate one by executing ssh-keygen. This command will generate a public key (~/.ssh/id_rsa.pub) that will be necessary later on.

[user@mycomputer~]$ drm4g resource edit
[meteo]
enable            = true
communicator      = ssh
username          = user
frontend          = mar.meteo.unican.es
private_key       = ~/.ssh/id_rsa
lrms              = pbs
queue             = short
max_jobs_running  = 2
max_jobs_in_queue = 6

2. List and check if resource has been created successfully :

[user@mycomputer~]$ drm4g resource list
RESOURCE            STATE               
meteo               enabled

3. Copy the public key (~/.ssh/id_rsa.pub) to authorized_keys file on the remote frond-end, and adds the private key to the agent for the ssh authorization:

[user@mycomputer~]$ drm4g id meteo init 
Starting ssh-agent ...
 WARNING: ssh-agent is already running
--> Add '/home/user/.ssh/id_rsa' into ssh-agent for 168 hours
 Lifetime set to 7 days, 0:00:00
--> Copy '/home/user/.ssh/id_rsa' to ~/.ssh/authorized_keys file on 'ui.macc.unican.es'

4. Show information about the identity:

[user@mycomputer~]$ drm4g id meteo info
--> Display '/home/user/.ssh/id_rsa' key
ssh-rsa AAAAB3NzaC1yc2EAAAADAQAABAQDcUYc9tDOYptqAWf7YzgN2NY9F+AtObtVvgh0PsIWZvDx1ml6j9n7zihiHFwnNIQh1q1EpIku/Jg8kyKOnbpm+2prnIhURoAWxO+rlzCF0Q4hHHW5svNNR6doCZ9mNNswi1uHaVpwhu8EKgfPyH+oNI/inSnJ/QQRHILyjUvaNbQPuXwVBpYjpvOAFOYA2VZqi+IfTq13lks7DCBfv3DK1w38aDQ9xFP/hYlQKwC/DwJo1q2CWxg5WZhgHFRG/1nyVH/nTbjOMTRZS61Gre58UUab/wSZQc6rTkrTitnCdAujIUx5eiOhM90JfDj+VUriLTnXCkwUC4+h

That's it! Now, you can summit jobs to meteo.
