/**
 * Acquires nodes provided by an existing PBS cluster
 * <p>
 * The point of this Infrastructure is to interface with
 * an existing installation of a PBS (ie Torque) Scheduler:
 * node acquisition will be achieved by running
 * runtimes as Torque jobs: submitting a job acquires a node,
 * killing it stops it.
 * <p>
 * PBS jobs will be submitted through SSH from the RM to the PBS server;
 * make sure the RM and the nodes will be able to communicate once
 * the node is up.
 * <p>
 * If you need more control over you deployment, you may consider
 * using {@code GCMInfrastructure} instead, which contains the
 * functionalities of this Infrastructure, but requires more configuration.
