/**
* 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.
