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 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.
