The cluster used to be free for use. But the time has come (according to your representatives on the computer committee) to implement a queuing system. Our implementation uses the Torque (OpenPBS) queuing system. Most of the para machines are no longer directly accessible. In stead, you log in to paracluster and submit your job to one of the queues from there. More details on [[paracluster: | The cluster used to be free for use.
