Usage

torque::default

Default recipe installs the torque commons and create a user. Torque head and compute node recipe includes the default one so it should not be used alone.

torque::head_node

Head_node recipe installs the torque server and client packages and configures the job queue. It generates a key pair for the torque user and publishes the public key. It collects the compute nodes in the same environment and joins them to the cluster. Importan: If a compute node appears or leaves, the chef-client sould be issued again.

torque::compute_node

Compute_node recipe installs the torque mom package, prepare connection to the torque cluster and set up the torque user. Important: It requires a head node in the same environment.
