Specification of PBS Jobs

So far we have used PBS in its simplest form relying on defaults. We never had to specify queues or other job parameters. Although some of the specifications may be superfluous on the AVIDD cluster right now, because there is only one queue there and the queue has no limits imposed on it, nevertheless, you need to learn how to describe PBS jobs more elaborately, in case you want to use other facilities, e.g., NCSA, or in case AVIDD gets used more heavily in future and its administrators will be forced to configure a richer queueing environment. Furthermore we are going to learn some other tricks in this section that will be useful for conditional execution of various jobs, i.e., jobs that may depend on other jobs to run correctly.
