The PBS queue system allocates a set of nodes and processors to an individual job, either for the walltime specified in the job or the maximum walltime in the queue. It then provides a set of environmental variables to the shell in which the script runs, such as PBS_NODEFILE, the temporary node file describing allocated CPUs.
